Controlled Speed Limiting System for Congestion Mitigation for Smart City Design

Intelligent transport system is the new aspect of smart city design under the purview of digital India. Conventional approaches like rerouting from congested paths, predictive control methods are impractical for Indian scenarios due to excessive growth of urbanization, unorganized and heterogeneous traffic nature. A novel framework is required to ensure smooth traffic, less congestion and avoiding accidents. This paper contributes towards the Intelligent Transport System (ITS) that provides a controlled speed limit to the cluster of vehicles according to present roadside conditions. Smart RSUs (Road Side Unit) are responsible for analyzing and controlling the road network. Several traffic metrics like travel time, vehicle speed and the effect of signal spacing on vehicular speed are analyzed with the designed system model and have compared them with the conventional uncontrolled scenario. This paper is mainly focused on Kolkata, the newbie smart city of India. It is observed that with the proposed design model for ITS, significant improvement of vehicle movement is achieved in a very congested hour avoiding stagnant conditions more often we face in Kolkata.
