What are the common problems with Traffic Signal Preemption System and how to solve them?
Preemption systems can greatly decrease response times for emergency vehicles. Different studies have calculated that a 15 to 50 percent reduction in response times and a 70 percent lessens in emergency vehicle crashes. These changes significantly affect the results of medical emergencies and have improved traffic safety considerably. Let’s take a look at some common problems with traffic signal preemption systems and some solutions to improve response times:- Line of Sight: Some preemption systems use infrared, optical, or radio technologies, which need a line of sight. As they do not pass between buildings, over hills, or around corners, which means emergency vehicles can be made to stop and wait for traffic to clear out before going forward. Traffic Jams: since preemption systems are only activated when an emergency vehicle is close enough to the intersection, therefore, they often can’t clear traffic in advance.
