Review of Emergency Vehicle Priority Systems

Abstract

Urban cities all around the world are suffering from increasing vehicular traffic density, increasing population density, narrow roads, and overburdened public infrastructure. As traffic jams become a common sight in urban cities, the average transit time for vehicles has increased. These trends have grave consequences for emergency vehicles like ambulances which need to reach their destinations in the shortest time possible. Taking advantage of miniature processing units, communication networks, many systems have been designed to address this problem. The systems which aim to reduce the transit time of emergency vehicles are called Emergency Vehicle Priority (EVP) systems. EVP systems are systems that control the flow of traffic efficiently to let emergency vehicles travel faster. In this paper, we present a review of different EVP systems.
