A smart traffic solution for High Priority Vehicles

Abstract

Traffic lights are designed to ensure smooth traffic in the cities. The current traffic system is running same over the past few years. As number of vehicles on the roads is increasing constantly, this system is failing to serve traffic congestion problems especially on the intersections. Due to traffic congestion High Priority Vehicles (HPV) also get stuck in traffic which results delay in their services. HPV like ambulances, fire brigade etc. have to serve various causalities. It is very important for HPV to reach on time. There is a need of system that aims to provide path to HPV to reach as quickly as possible. The proposed work provides priority based approach. It aims at building a user interactive system for HPV in which an HPV driver can send request to the system to which the system responds smartly. Priority of Road Segments (RS) at an intersection is calculated and traffic light turns green for the RS with highest priority. The algorithm is tested on SUMO (Simulation of Urban Mobility) and it has shown positive results by saving more than 50% time in various traffic intensities (low, moderate, high).
