A somewhat common issue at many facilities seems to be that traffic is unable to pass through a traffic light without several iterations of green during peak hours. This leads to lengthy idle times and constant stop and go that are unnecessary as well as detrimental to the environment and the vehicle itself.
A simple solution would be to increase the time a light stays green during times of high traffic flow. Allowing more cars to pass through a single green light (hopefully all cars if the wait time were reasonable) would be better for the environment and shave precious minutes off the commute to and from the workplace. Implementing this could be as simple as adding X amount of time, performing a traffic study to determine the appropriate amount to add or installing traffic cameras to sense if there are still vehicles at the light.
