Sustainability Topic: Waste (in terms of efficiency), Energy
I like this article because it gets down to the basic principle of a ‘smart city’ – you use the measurable data of a city to identify where to make improvements, and you go out and make those improvements. You don’t need to improve the ridership of the MTA with some sort of cloud-based ridership benefits app that uses IoT technology to make your blender give you compliments each time you make a smoothie: you can simply fit more people on a subway by making more space. And to make more space you can remove seats. Summary below.
- E trains had delay troubles, because of overcrowding on their trains. This manifested primarily in longer loading and unloading times at stations.
- They determined they could ease the issue of overcrowding by removing some seats from certain E train cars.
- The seats were removed from the door areas, so more people could fit as well as more easily enter and exit.
- Each modified train has an increased capacity of around 100 riders.
- Additional changes to the E line such as equipment replacements are also being accelerated to address the efficiency issues with the service.
- A result of these changes is: the riders experience less delays, and more are served by the train.
- Since time can be measured in terms of the opportunity cost of productivity, both of these changes should help the economy.
- Since the train cars are moving more people per trip, they are increasing their energy efficiency.

Three Next Steps:
1 – Evaluate the impact of the changes. Is the issue of delays being addressed?
2 – Conduct an analysis of other train lines that have similar issues.
3 – Expand the seat removal pilot to these other lines.
Comment on another blog: “Larvae convert food waste”
A very neat idea – another impact the article discusses is that much of conventional fish feed comes from trawling the ocean, a habit that contributes to overfishing. These larvae would help mitigate that effect as well as the food waste.
