Traffic Congestion is a big issue. Time taken for traveling will be increased because of this congestion problem; a solution was looked into with the help of wireless technology with some specific development sensors and boards. An algorithm was also designed to ensure that many vehicles can go through a signal. Priorities would be given to some categories of vehicles. For example, emergency vehicles like fire trucks, ambulances, etc. would be prioritized. So, a good Traffic Signal Monitoring System plays a vital role in managing traffic, mainly in highly congested urban regions.
