Design of Indian Navigation Satellite System-Based Traffic Management for Entire City

Indian Space Research Organization (ISRO)’s satellite technology has emerged on the global scale with its own IRNSS (Indian Regional Navigation Satellite System)—NavIC (Navigation with Indian Constellation) in outer space, and this paper aims to exploit one of its applications in traffic management for the complete city with inter-connected squares. This paper projects a novel design towards using NavIC to determine position of the vehicles, and as per their directional motion, number of vehicles moving towards particular road of any designated traffic square is determined. Suitable state machine and flow diagram are designed considering the real-time data. “Hand-over” mechanism is proposed to reduce the design complexity in terms of software implementation. Accordingly, the counter is made adaptive and dynamic. The finite-state machine (FSM) consists of 50 states, and very high-speed integrated circuit hardware description language (VHDL) coding and simulation are done using Libero SoC v11.9, Xilinx ISE 14.7 and ModelSim Microsemi 10.5c.
