Vehicle-To-Grid

1. Problem: Unidirectional Grid-To-Vehicle Charging   

Fossil fuels from internal combustion engine vehicles as well as electricity generation from coal and natural gas emit greenhouse gases that cause global warming. To decarbonize transportation and electricity, renewable energy sources are needed. Since the sun and wind are not always present, energy must be used immediately or stored. Upgrading residential and commercial buildings with battery storage is expensive and time-consuming. The batteries inside electric vehicles (EVs) provide an opportunity for power without resorting to fossil fuel sources. However, traditional grid-to-vehicle (G2V) charging stations are unidirectional. 


2. Solution: Bidirectional Vehicle-To-Grid Charging

Vehicle-to-grid (V2G) technology provides bidirectional charging for plug-in EVs, battery EVs, plug-in hybrids, and hydrogen fuel cell EVs. V2G provides drivers demand response services with the ability to send electricity into an EV battery as well as sell this energy back to the grid. EV batteries are the most cost-efficient energy storage solution since no new hardware investment is needed. With broad deployment, V2G could improve grid stability and reduce stress to meet peak demand from renewable sources. This will ultimately reduce carbon emissions on the journey to net-zero. Key features include:

— V2G EV charging equipment enables the flexible two way flow of electricity. 
— EV drivers select charging or selling electricity to the grid with a mobile application. 
— Drivers set minimum charge levels, plus view charging updates and history. 
— The charge management system enables and monitors V2G charging features. 
— Drivers save money via credits to reduce the total cost of ownership in participating markets.
— Using EVs for grid storage may impact battery life based on a finite number of charges.

Vehicle-to-everything (V2X) expands use cases to include vehicle-to-home (V2H), vehicle-to-building (V2B) and vehicle-to-grid (V2G). The V2X ecosystem at scale can reduce the need for new power plants by tapping into EV batteries as distributed energy sources.


3. Stakeholders

The stakeholders in the V2G ecosystem include: 

— Charging Station Hardware Manufacturers: Dcbel and Coritech Services manufacture and sell residential fast chargers with V2G features.
— Charging Software Integrators: Virta provides V2G charging integration services for businesses. The mobile app allows an EV battery to remain 70-90% charged. 
— Car Manufacturers: Nissan is the only major manufacturer making V2G compatible cars with the Leaf and e-NV200. Other manufacturers are conducting V2G research and development. 
— Consumers: Drivers must buy EVs with V2G charging capabilities and enable these features. 
— Real Estate: Public and private site owners must approve V2G charging deployment. 
— Utilities: EDF is a Britain utility company that provides V2G charging energy bill savings. Other utility companies globally must develop and implement V2G programs.
— Policymakers: V2G incentives must be developed to spur adoption by market participants. 


4. Implementation

Significant market development is required before V2G can be deployed at scale to meet peak energy demand. Key challenges for V2G include:

1. The adoption of V2G standards by the majority of car manufacturers for future car models.
2. Utility network upgrade costs and standards for widespread bidirectional energy distribution. 
3. Policies that incentivize V2G public private partnerships. 

For car and utility companies that are currently V2G ready, the implementation steps include: 

1. Residential or business customers confirm V2G site feasibility with the utility company. 
2. Customers complete any utility grid interconnection requirements. 
3. Once approved, customers purchase and install a V2G ready EV charging station.
4. Customers signup for a V2G digital service accessed by mobile app and dashboard. 
5. Customers receive credit for energy sold back to the grid.

Electric Vehicle Wireless Charging

1. Problem: Electronic Vehicle Wired Charging   

The lack of public charging options creates range anxiety that prevents internal combustion engine car drivers from buying an electric car. Electric vehicle charging with a cable generates friction when outdoors in cold or wet weather. Although the J1772 electric vehicle charging standard is gaining widespread adoption, driver must still make sure each charging station works with their car. Public charging stations increase street furniture in communities. Traditional public charging stations deployment can create trip hazards for pedestrians. 

2. Solution: Electronic Vehicle Wireless Charging

Wireless Electric Vehicle Charging Systems (WEVCS) reduce friction for drivers by preventing the need to plug in. Wireless charging also reduces street clutter and the hazard of tripping over cables. Once a driver parks above a charging pad, the car starts charging via resonant magnetic induction. Automakers and suppliers have agreed on a wireless power transfer (WPT) standard to charge electric and plug-in hybrid vehicles. SAE International develops and promotes standards for the aerospace, commercial vehicle and automotive industries. In November 2020, the SAE J2954 inductive charging standard was accepted by car manufacturers. Key features include:

— Wireless signals sent between the car and charging system to initiate and stop charging.
— A charging pad that is about one square meter and receiving pad integrated under the car. 
— Enabling increased interoperability between hardware and software across manufacturers.
— Achieving 94% efficiency compared to wired connections ranging from 3.3 to 20 kilowatts.
— The potential to enable autonomous cars to charge themselves without human interaction.

Wireless Charging Companies:

— Witricity provides 3.6kW to 11kW wireless charging from in-ground placements in asphalt and cement with foreign object detection, live object detection, and position detection.
— Plugless Power provides 3.3kW and 7.2kW wireless EV charging stations. Purchase of the charger includes hardware and installation to upgrade an EV for wireless charging.
— Wave provides fast wireless EV charging for buses with deployments up to 250kW.  

Dynamic WEVCS is a potential future technology to charge electric vehicles while driving by embedding roads, such as highway sections, with charging transmitters.

3. Stakeholders

The stakeholders in the wireless charging ecosystem include: 

Wireless Charging Providers: Witricity, Plugless Power, Wave and other providers. 
Car Manufacturers: BMW, Honda, GM, and Nissan are all Witricity development partners.
Consumers: Drivers must buy future cars with EV wireless charging capabilities. 
Real Estate Owners: Public and private site owners must approve wireless charging sites. 
Utility Companies: Energy distributors must support standards and interconnection to the grid. 
Policymakers: Politicians must generate policy that allows wireless charging deployment. 

4. Implementation

It  remains questionable if wireless charging will be implemented and deployed at scale. Cost and deployment hurdles must be solved in order for wireless charging to gain traction. Wireless charging requires: 

1. Refinement of wireless charging systems to provide auto manufacturers confidence to deploy this technology. 
2. Wireless charging pilots with public and private partners to get support for widespread deployment. 
3. Assuming barriers are overcome, each site will require approval from public and private real estate owners. 
4. Once a site is confirmed, ground pads will require utility companies to confirm interconnection requirements. 
5. Upon gaining utility approval, ground pads will require permitting, leasing, provisioning, and construction. 
6. The wireless charging system can then be installed. 
7. Drivers can then gain the benefits of wireless charging. 
8. The wireless charging system will then require operating and maintenance by the provider.

Micromobility Charging

1. Problem: Dockless Micromobility Charging  

Micromobility companies have traditionally relied on dockless parking and charging. This results in cluttered sidewalks with increased risk of fire from charging multiple e-scooters and e-bikes at residential locations. Micromobility service providers face challenges charging and maintaining fleets. Companies rely on gig economy workers to scour cities and charge depleted e-vehicles at home overnight. As companies scale, they pile e-scooters and e-bikes in internal combustion engine vehicles to recharge in warehouses. This limits environmental benefits, availability, and potential revenue. This charging ecosystem is expensive so new charging solutions are needed. 


2. Solution: Universal Micromobility Charging Stations

Companies are working to solve these challenges by developing universal micromobility charging stations. GetCharged, Inc. (Charge) provides micromobility stations for riders and service operators to charge e-scooters and e-bikes. Charge is dedicated to building the largest network of electric charging, storage, and service stations for e-vehicles. These stations remove clutter on city sidewalks and reduce hazards for pedestrians. The first Charge docking station was launched in August, 2019 on Broadway between 24th and 25th street. Key features:

— Charge’s docking charging stations are compatible with most e-scooter and e-bike brands. 
— Universal charging stations connected to the grid can fully charge a battery in 3 to 6 hours.
— In addition to charging, docks provide adaptable micromobility vehicle parking and locking.
— Docking charging stations are installed in private garages, lots, and spaces.
— Charge is deploying over 400 locations in NYC and 6,000 across the US and Europe.

Other Micromobility Charging Station Providers: 

— PBSC organizes, secures, and charges e-bikes and e-scooters while reducing operating costs.
— Swiftmile has a solar-powered charging station with digital display for transit details and ads.
— Kuhmute is a modular and universal charging station for micromobility providers and cities. 
— Duckt combines a dockless and docked approach with a unique locking system. 

Universal Battery Swapping 

Universal battery swapping is an alternative approach for micromobility charging. This solution reduces waiting time since batteries can be swapped in a few minutes. The battery swap can be done anywhere with battery swap cabinets taking up less space than public charging. However, universal batteries face challenges for e-mobility company adoption. When battery technology is upgraded, the charging network requires upgrading so this solution prohibitively expensive.  

3. Stakeholders

The stakeholders in the micromobility ecosystem include: 

Charging Service Providers: Companies including Charge, PBSC, Swiftmile, Kuhmute, and Duckt provide innovation micromobility charging solutions. 
Micromobility Service Providers: Companies including Lime, Bolt, Bird, Revel provide e-scooters in various markets that require charging.   
Consumers: City residents become members to micromobility service providers to efficiently travel around neighborhoods. 
Real Estate Owners: Private parking owners and the Department of Transportation in cities become stakeholders to provide sites for micromobility charging stations. 
Utilities: ConEdison in New York and PG&E in California are examples of utilities that must manage the deployment of micromobility charging stations.
Policymakers: City politicians are shaping micromobility charging policy and regulation.


4. Implementation

The micromobility charging service providers take the following key steps to deploy:

1. Meet with public or private real estate owner to gain approval for charging station project.
2. Once interest is confirmed, meet with utility to confirm project feasibility at the location. 
3. Gain approval for charging station installation construction, trenching, and permitting. 
4. Install the micromobility charging station at the desired location. 
5. Operate and maintain the charging station once up and running.

Micromobility charging stations

Student: Jessica Yu (Uni: JY3076)

Sustainability Problem:

Solar Power stations and infrastructures have been increasing in many places thus bringing down the cost in many homes. However, there are still many areas where the grid does not reach the areas and it is hard to gain energy access on the go.

Summary:

In order to make energy / charging stations available, standardize and universal charging station needs to be made available, DUCKT is a company that helps create this, gives access and creates a new stream of energy towards public transportation. DUCKT can charge any micromobility vehicle including scooters regardless of model in one infrastructure solution.

  • This company helps create a infrastructure that is suitable for many vehicles in the market. For example, in Paris, they deployed new charging infrastructure that can be plugged into advertising boards or streetlights.
  • DUCKT ( https://medium.com/startup-grind/startup-q-a-duckt-6306b15e3288) says its charging docks can be plugged into advertising boards, bus stations and street lighting to provide a power source, meaning scooters for example can stay in use for longer without the need to have batteries replaced.
  • The city of Paris has begun a pilot project to install 150 dock, lock and charge points for micromobility vehicles across the “Paris Rive Gauche” (13th Arrondissement) area of the French capital. The project aims to demonstrate how universal charging infrastructure can accelerate micromobility use and it’s hoped reduce climate impact in the city.
  • Scooters are very popular in the cities, so providing sufficient infrastructure will no doubt become crucial for authorities in the capital going forward. Time will tell whether projects such as this will be rolled out more widely in Paris and other cities where scooter usage is increasing.

Stakeholders

  • Public Space Owners (Key Stakeholders): While service operators are visitors of the city, people and the local authority are the hosts, and the hosts of the city are the one who will be impacted in their daily life
  • Sharing Operators (Primary Stakeholders): Firms are spending almost 60% of their income for operations and charging. Operators can cut from their extra operation times, especially to charge during the day anytime, anywhere. DUCKT Station provide safety against vandalism both during the day and night
  • 3rd party Business (Secondary Stakeholders): Parking operators, energy suppliers, coffee chains, EV stations, Shopping centers, holiday resorts, gas stations get to become mobility service hotspots.

Deploying this technology

Work with cities local authorities and scooters operators to present this solution to implement as a standard that benefits all. Furthermore, they also can work with scooter manufacturers because they have internationally patented the plug works in how it’s designed, they can have these adapters as a spec ready into these vehicles so they will already have a infrastructure solution that is already existing in the cities.

Open Charge Point Protocol

1. Problem: Electric Vehicle Charging Fragmentation
Sustainability Category: Energy Management, Mobility

29% of total greenhouse gas emissions in the United States are from transportation with internal combustion engine vehicles being the highest source. With only about 1% of cars on the road being electric today, range anxiety from the lack of widespread charging infrastructure is a primary adoption barrier.

As the electric vehicle (EV) charging technology sector develops, closed charging infrastructure networks generate friction for hardware manufacturers, software developers, and drivers. Electric vehicle infrastructure developed by private network operators create silos that limit value for stakeholders. Industry fragmentation forces EV drivers to join multiple networks with varying accounts to access public chargers. The lack of standards leads to duplicative development effort to integrate charging stations and backend networks with energy systems. This limits providers from offering additional features across all providers.


2. Solution: Open Charge Point Protocol (OCPP)


The Open Charge Point Protocol (OCPP) is a charging infrastructure standard for EV charging station, Electric Vehicle Supply Equipment (EVSE), and back end software communication. OCPP reduces friction and fragmentation by increasing flexibility across the electric vehicle infrastructure industry for organizations and drivers.

— OCPP is an open-source, free standard published by Open Charge Alliance (OCA) that enables interoperability between charging infrastructure hardware and software networks.
— This neutral, open standard enables charging station vendors to access, share, and collect data with backend charge management operators so the widest amount of products can work together.
— On the charging station, OCPP enables charging station discovery, reservations, session authorization, billing information collection, and real-time charging data.
— On the backend software, OCPP enables real-time status of charging stations, remote charging session control, firmware management, and error notification.
— OCPP 1.6 is a JSON protocol that was released in 2015 and is the most widely used version in market today. OCPP 2.0 was launched in 2018 and provides major data encryption security updates. OCPP 2.0.1 is the latest version and was launched on March 31, 2020.

3. Stakeholders

OCPP is primarily utilized by charging station product, design, and engineering teams. Key organizations that are stakeholders in the OCPP ecosystem include:

— Open Charge Alliance (OCA):An international consortium of private and public EV infrastructure organizations that leads OCPP development, adoption, and certification.
— Network Management System Providers: GreenLots and ChargeLab are two EV charging network software providers that manage charging stations across manufacturers via OCPP.
— Charging Station Manufacturers: Blink and EVBox are two EV charging station manufacturers that use to connect devices to OCPP supported backend systems.
— EV Drivers:Mobile applications across providers initiate and manage charging sessions.
— EV OEMs: Manufacturers integrate OCPP on the in-car display to manage charging sessions.


4. Implementation

Once a hardware or software company decides to use OCPP, the following steps are taken:
1. The product management team will integrate OCPP in the roadmap and define requirements.
2. The design team will incorporate the OCPP functionality into hardware or software features.
3. Once approved, the engineering team will develop, test, and deploy OCPP features.

Smart Urban Growth Tackles Mobility and Electricity Distribution Concurrently

Cities can get smart taking control of their electrical grid and electric vehicle (EV) charging infrastructure as a means of addressing urban growth.  Boulder, Colorado is making a run at it but few outside Germany have taken a serious move in this direction for it requires a long-term vision.  Seeking this urban planning route is not always initiated for economical reasons.  Boulder, for instance, is driven to engage as a means of increasing renewable energy sources in their electricity generation fuel mix.  Here’s the catch, this approach may not a scalable or sustainable solution for all cities  Mega cities; no way anytime soon.  Rural environments; not likely ever needed.  So, Boulder just happens to sit in the Goldilocks Zone but even with it being “just right” the increasing digitalization of the electric grid and new sources of distributed energy will make this endeavor a tenuous pursuit.

Years ago I was involved in dozens of negotiations with municipalities throughout the United States, Canada, and Mexico.  Many desired to “take control” of and then offer, as a public service, wireless Internet services for their citizens.  The complexities in equipment management and selection, maintenance, and budgeting were often solely regarded in the context of whether to make the WiFi a free or a for a fee amenity to subscribers.  Thing is, that’s not where the root challenge existed.  Even a little bit of education in these matters achieved a stakeholder stalemate for trying to figure out how to convert a privatized service into a public good without causing bias to an ongoing free market was no simple matter.  The concept of a public-private partnership was alien.

Dealing with increasing urbanization today requires a systemic stakeholder analysis and just the right sitting of pilot efforts in advance of any at-scale execution plans.  To date few cities have taken this approach but Toronto, Canada is on the way.

“...We are designing a district in Toronto’s Eastern Waterfront to tackle the challenges of urban growth…Sidewalk Toronto will combine forward-thinking urban design and new digital technology to create people-centered neighborhoods that achieve precedent-setting levels of sustainability, affordability, mobility, and economic opportunities” – Sidewalk Labs

To do as Sidewalk Labs proposes there must be an integration of technologies, policies, and financial mechanisms that allow for private and public implementation plans to surface, ones in service of many stakeholders.

  • SAMPLE TECHNOLOGIES AT PLAY
  • IMPLEMENTATION APPROACHES
    • Analyze long-tailpipe electricity generation fuel mixes
    • Promote EVs and pilots ONLY in cities that have clean fuel sources
    • Establish population growth and transport demand metrics
    • Conduct customer interviews to fit future needs
    • Create intelligent city policies to cater to DER and EV microgrids
    • Engage private-sector electric mobility companies
    • Educate citizens on mobility and clean energy options
    • Build neighborhood based pilots
    • Engage citizens via engagement workshops for updates
    • Prepared to pivot for at-scale execution
  • STAKEHOLDERS TO ENGAGE
    • City Planners & Urban Designers
    • Public Entities and Administrators
    • Private Technology Providers
    • EV Manufacturers & Infrastructure Providers
    • Load Balancing Software Solution Providers
    • Private and/or Public Electric Utilities
    • Citizens

 

JMB2408 COMMENT TO ANOTHER BLOG POST (Leaf Plates):

This is an excellent solution to consumption and in turn waste. If this was a compostable solution that can be put to use in the local houseplant or compost pile then we’re talking about a dream conversion in consumption to waste. The other thing that would be amazing is to see this scale to shipping boxes or other high consumption transport items. Awesome find, thanks for sharing.

Smart Fabrics – no wires or batteries

 

Sustainability Problem: Real time data on workers, reduce injuries

For first responders information on victims and types of injuries are vital in order to determine the necessary procedures to perform.  As a result, speed is vital and decisions are made in seconds.  Information is not always readily available to first reconsiders  when they arrive to an emergency scene. Every year, thousand of people are misdiagnoses and/or treated incorrectly due to lack of information on the injury and/or the victim’s medical history.

Most smart fabrics are not sustainable because they require electronics and  batteries.

 

Sustainable Technology: Smart fabric

  • Researchers at the University of Washington developed a smart fabrics that holds magnetize text that can store small amounts of data readable by a magnetometer.
  • The fabric can interact with storage devices without the need for onboard electronics or batteries.
  • Individual’s emergency medical history can be stored on the fabric.
  • First responders can scan a victim’s clothing to gather vital statistics – e.g., blood pressure, heart rate, allergies, etc.
  • This fabric is more sustainable since it doesn’t require any electronics and / or batteries.
  • Fabric maintains magnetic field after washing, drying, and ironing.
  • Fabric can be encoded with security information to access secure locations (e.g., home, office building, etc.. )

https://www.technologyreview.com/s/609264/your-next-password-may-be-stored-in-your-shirt-cuff/

Organizational Stakeholders that Will Use the Technology:

  • Researchers at U. of Washington (Justin Chan, graduate student)
  • Prof. Shyam Gollakota, U. of Washington
  • U. of Washington Networks and Mobile System Lab

First 3 Steps in Deploying the Technology:

  • Continue testing fabric and weather proof
  • Increase longevity of magnetic field (declines over the course of a week)
  • Increase data storage capacity.

 

Comments:

The technology mentioned below can be used in natural gas / oil pipelines to monitor leaks. Every year, there are thousand of leaks in gas / oil pipelines. The majority of the leaks go undiscovered for days and/or weeks before discovered.

Cities Get Smart by Prioritizing Mobility

By 2030, 60 percent of the world’s population will live in cities, up from about 50 percent today.  Planners and designers swiftly get transportation logistics, congestion, and air pollution, but when pushed to make urban life better for their citizens they often fail to deliver.  Some urban areas already rank above average and offer integrated multi-model mobility options but these complex offerings to deploy.  Mobility technologies exist (see below) that ease the pain when prioritizing mobility but this is not merely a “tech fix” situation for it requires collaborative stakeholder engagement and implementation planning as well.

Copenhagen has for a long time now housed parking lots full of bikes, their transport lanes throughout the city prefer pedal pushers, and when I was recently there nearly everyone told me they bike more than they use an automobile.  London is building “cycle superhighways” and New York expects to have 1,800 miles of bike lanes by 2030.  Thus, the challenge of bringing smart mobility solutions to urban dwellers doesn’t require fancy new technologies but instead lies in the requirement to establish collaborative planning processes that educate, iterate, and ultimately are built with flexibility in mind.  When driven by the urban subculture it’s apparent.  I just returned from Boulder, Colorado and when there I saw municipal bicycle storage options integrated with public transportation lines; a natural extension of the daily commuters lifestyle.  Don’t think this is something we’re going to see in Atlanta, Georgia anytime soon!

Don’t get me wrong, municipalities are working hard to solve these mobility issues, this isn’t just about meeting citizen’s demands pushed at planners and designers.  Heterogeneous trends in urban mobility have been slowly coming online and one of the most touted “technology” solutions is the high occupancy vehicle (HOV) lane.  The start of smart planning to better manage congestion but then that was taken the next step through innovative laws in states like California that now allow HOV access for electric or hydrogen vehicles too.  Right on the heels of HOV lanes came congestion parking in major metros like New York City and the concept of peak demand parking sits at the bleeding edge of urban mobility, despite nobody having worked out the math just yet.  In fact, new business models are continually trying to deal with the needs for increased data collection and logistical management analysis.  This is clearly the direction smart cities are going but in my research this isn’t as far as it will go in the coming decades.  What comes next will seem extreme but population growth and the demands of urbanization on cities will require ultra efficiency.

For a hint into the future just look at Singapore.  Albeit they’re an island, but because of this they’ve been pushed to their mobility limits ahead of other major metros.  They’ve opted to set aside cars all together and this isn’t solely because they can’t build more suburbs for their commuters and cars.  They’re aware of the laden energy in costs in vehicle manufacturing and the significant potential to reduce CO2 by switching from gas powered automobiles to walking, biking, and electrified forms of mass transit.  In fact, as the Singaporean government lowers their transport and mobility energy profile, they’re guaranteeing the citizens will be able to live healthier lifestyles.  This effort paves the way for systemic shifts and opens the door for a sustainable mobility future; one inclusive of drone package delivery drops, self-service mail centers, automated vehicles (passenger, bus, tram, freight, and corporate fleet solutions), and allows for mobility as a service to flourish as well.

Cities wanting to establish integrated mobility plans and capture the full range of transportation and mobility solutions must take assessment of technology options, perform collaborative stakeholder analysis, and comprehensively implementation plans with a citizen centric approach.  Here are a few places to start:

  • SAMPLES OF URBAN MOBILITY “TECHNOLOGIES”
    • Congestion Pricing – HOV driving lanes, street, & parking
    • Urban Redesign – mobility optimization, curb, & intersection plans
    • Coordinated Actions – private & public sector collaboration
    • “Cycle Superhighways” – extra wide lanes dedicated to bicycles
  • ABBREVIATED IMPLEMENTATION STEPS
    • Establish population growth and transport demand metrics
    • Conduct customer interviews to fit future needs
    • Define the city and citizen archetypes
    • Create intelligent city policies
    • Engage private-sector mobility companies
    • Educate citizens on multi-mode mobility values
    • Leverage academic and startup incubators or accelerators
    • Build neighborhood partnership test pilots
    • Schedule citizen updates via engagement workshops
    • Act boldly and prepared for agile adjustments
  • KEY STAKEHOLDERS
    • City Planners & Urban Designers
    • Public Entities and Administrators
    • Academic Institutions
    • Accelerators and Incubators
    • Technology Mobility Solution Providers
    • Citizens

JMB2408 COMMENT TO ANOTHER BLOG POST (Fast-Charging Busses):

This is conceptually really “smart” but I wonder about what they claim to be able to do vs. what can actually be done. It’s logical to see this sort of quick charging take hold on the public transport lines and it really improves the efficiency of energy use but it’s not a straight forward fossil-fuel free solution until the energy comes from that source. Perhaps in France, with all the nuclear, it makes this ring true but if you put this in Wisconsin it won’t for all you’re doing is displacing the fossil-fuel from the source point at the vehicle to the power generation location. In my analysis there are many instances where the electrification of the transport sector makes things worse for CO2 emissions. Then again, local air quality will always go up so it depends on the objective of the smart city – local solution, regional, or global.

Thanks for sharing, cool tech and more to come I’m sure.

Surtrac – AI enabled traffic signals

1) Sustainability problem: Vehicular idling and congestion in traffic stops. Area: Civic Engagement, Mobility. 

  • Idling in rush-hour traffic  costs the U.S. economy $121 billion a year, mostly due to lost productivity
  • It also produces about 25 billion kilograms of carbon dioxide emissions.
  •  In many urban areas, drivers spend 40 percent of their time idling in traffic.

2)  Technology

  • The Surtrac or Scalable Urban Traffic Control system relies on computerized traffic lights coordinating closely with each other. Radar sensors and cameras at each light detect traffic. Sophisticated AI algorithms use that data to build a timing plan that moves all the vehicles it knows about through the intersection in the most efficient way possible.
  • Each signal then sends the data to traffic intersections downstream so they can plan ahead and can avoid congestion.
  • Surtrac system is interoperable and can use DSRC technology for Vehicle to infrastructure communication, where street signals “talk” and rely data to smart vehicles in real time.

  • Road transport commuters.

4) Deployment 

  • Research cities with highest intersection traffic congestion
  • Partner with the DOT and local governments to install the SURTRAC system in those areas
  • Reach production at scale so as to being down cost of installation of each SURTRAC unit.

JV2610  COMMENT TO ANOTHER BLOG POST (Bacteriophages improve food safety and animal health issues) :

“Antibiotic resistance is one of the major challenges facing the global health community and better alternatives are needed in order to prevent mass causalities from anti-biotic resistant bacteria. The Bacteriophages used in BAFASAL are viruses that need a bacterial cell to replicate. Once they infect a bacterial cell, they quickly replicate using the host cells RNA and other vital proteins and then “lys” or kill the bacteria when the new phages emerge from it. Proteon’s phage technology doesn’t affect the animal’s immune system.”

Transit Signal Priority (TSP)

Sustainability Issues

A well-functioning transit system is a essential component of any major city. However, in cities with narrow streets and high level of traffic volume like NYC, buses or other transit vehicles often trapped in busy intersections, resulting in traffic congestion and excessive air pollution emitted by standstill vehicles. According to a mobility report issued by NYC government, in n central business districts like Midtown Manhattan, Downtown Brooklyn, and Jamaica Queens average travel speed for buses are often 4 mph or less. Prioritizing traffic signal at busy intersection for buses could lead to higher travel speed of buses and therefore improve overall efficiency and service quality of the transit system.

Technology: Transit Signal Priority 

  • Transit Signal Priority (TSP) is a set of operational improvements for traffic lights that use technology to reduce dwell time at traffic signals for transit vehicles
  • Such a technology includes a detection system and a priority request generator aboard transit vehicles (or in centralized location)
  • As TSP equipped transit vehicles approach corridors, a signal will be sent by the priority request generator wirelessly to the traffic light control system
  • As the system receives the priority signal from transit vehicles, a set of pre-set strategies will be utilized to either hold green lights longer or shorten red lights until the transit vehicle pass the intersection
  • The same system could also be utilized to prioritize traffic signal for emergency vehicles like ambulances and fire trucks

Stakeholders 

  • Department of Transportation
  • Metropolitan Transportation Authority
  • Municipal government
  • Traffic signal providers

Deployment 

  • Identify intersections and corridors with highest traffic volume
  • Launched a pilot program to upgrade traffic signal system and install priority request generator in some transit vehicles (especially BRTs)
  • Evaluate effectiveness of the system and improve shortcomings
  • Employ the system in all transit vehicles and corridors to improve transit efficiency
