This document provides an overview of intelligent transportation systems (ITS) in India and Nagpur City. It discusses ITS developments in other countries like the US, Japan, and Europe. The objectives are to study overall ITS development globally and compare it to Nagpur's ITS. Components of ITS like advanced traffic management systems and advanced traveler information systems are described. Literature on ITS projects in various Indian cities is reviewed. Finally, the document analyzes fuel consumption and emissions reductions from implementing automatic signal synchronization on a corridor in Nagpur. Results show 1.5-2% reduced fuel use and decreases in CO and NOx emissions compared to the current system. In conclusion, ITS can help optimize Nagpur's transportation
