When timed properly they maximize the traffic handling capacity at an intersection. They also improve the safety for both vehicle and pedestrian traffic. Following the traffic study a decision is made to install or not install the signal. The Opticom system allows Fire and EMS vehicles to control the green light in order to speed response and protect the driving public. There are currently 35 intersections using the system and by the end of 2001 there will be 100 signal lights in the system.
Traffic signals are a very costly investment.
At this cost, careful consideration is necessary before installing new signals. At a flashing red light you must stop, yield to oncoming traffic or pedestrians, and proceed when the way is clear. At a flashing yellow light slow down and proceed with caution. When a signal is completely dark, due to power loss, the light serves to function the same way as a 4-way stop controlled intersection and drivers must stop before entering the intersection. Yes, there are many changes coming to our system.
