A Traffic Signal Preemption system is an automated system that allows normal operation of traffic lights at automated signalized intersections to be preempted. Preemption of signals is generally done to assist emergency vehicles, such as ambulances, so that response times are reduced and right-of-way is provided in a smooth and controlled manner. This paper proposes an innovative and cost-effective server-centric model to facilitate preemption using a simple mobile phone app which uses Global Positioning System (GPS) and a microcontroller which controls traffic signals.
