Lesson

Install detection sensors overhead on existing signal mast heads when possible, instead of using in-ground sensors to reduce both initial costs and maintenance costs.

The experience of Midtown in Motion project by NYC DOT with advanced signal control systems.

Lesson Learned

Installing detection sensors for their 100+ block advanced signal control system overhead on existing signal mast heads saved construction and maintenance costs. Installing above ground sensors on signal mast heads was cheaper than installing new poles or gantries. NYC DOT opted to remove the sensors from the roadways because "'[it] was extremely difficult, if not impossible, to maintain them at a level that you needed to, due to utility cuts and just regular wear and tear,' [NYC DOT director of Systems Engineering John] Tipaldo comments. 'So everything we're using is non-intrusive.'" By removing the necessary sensors from the roadway, they reduced the likelihood that the sensors would need to be replaced due to construction or damage.
