§Some of the environmental apps being researched include:
§Eco Approach and Departure at Signalized Intersections: Presents information
to drivers about traffic signal timing, allowing drivers to adapt their speed to pass
the signal on green or decrease speed to a stop in the most eco-friendly way possible.
Signal Priority: Gives signal priority to transit vehicles approaching a signalized intersection, considering the vehicle's location, speed, type, schedule,
and number of passengers--to produce the fewest emissions at signalized intersections.
Signal Timing: Traffic signals collect data such as vehicle type, location, speed and emissions from vehicles to optimize traffic signal timing.
