What are the common problems with Traffic Signal Preemption System and how to solve them

1. 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. Uncertainty:- Emergency vehicles coming to an intersection with a green light might need to find out whether the signal has actually been preempted or not. Stop Times:- Sometimes preempted signals stop motorists for too long, which can “provoke disrespect for the red signal.” So, ensuring that the signal returns to normal operation as quickly as possible after an emergency vehicle has passed through it is important. Congestion: Researchers have noticed that once a signal is preempted, the coordinated systems can recover to normal operation from 30 seconds to seven minutes, depending

2. on the location. But during high traffic hours, these interruptions can lead to major delays for all the transport at the intersection and nearby roads. Reporting:- Many traffic signal preemption systems don’t have any reporting. These are important to make sure of an effective response. While emergency vehicles might record their response times, combining information and analyzing it to find ways to improve it over time becomes difficult. Smart City Solutions:- Smart city solutions help make preemption systems safer and more efficient by bringing in next-generation technologies, such as GPS and cellular modems.
