Traffic Signal Preemption (TSP) system for ordinary vehicles in case of emergency based on Internet of Things ecosystem

The development of internet-of-things and mobile application development taking in consideration the increase in number of smart phone users has opened a new horizon for solving one of the significant issues of saving life in case of emergencies. We present a novel intelligent Traffic preemption systems that allows the vehicles to preempt and operate the traffic intersections with the help of mobile devices, in case of emergencies on the way to hospitals in order to reduce the delay and improve the response time. In this paper we discuss the design and implementation of a non-obtrusive, cost efficient and a reliable system that helps in traversing the vehicle easily through a congested traffic intersection via a smooth and fluent path. An Internet of Things ecosystem is developed that can be preempt traffic signals using a mobile application via internet. The web server has to be configured to accept such connections and store the metadata in a database. Authentication measures have been taken in account so that the system is less vulnerable to get misused. The theory, design procedures, and discussions of the system are presented.
