Chennai is the largest industrial and commercial center of south India and a major cultural, educational, and economic center. It is well known for its developed automobile industry and a rapidly growing number of financial services and information technology companies. Industrial developments and increased economic activities have attracted people for better livelihood and employment opportunities. According to the Chennai Master Plan 2026, the population is expected to reach 12.5 million by 2026. Existing public transport is incapable of meeting the current and future growing travel demands. Consequent to the lack of efficient public transport systems, the city is witnessing a steep rise in private vehicles on roads, leading to traffic congestion and pollution. To improve urban connectivity in the Chennai Metropolitan Area (CMA), GoTN has decided to put in place a metro rail system, implemented in phases. Phase I (Corridor 1 and Corridor 2) is already operational, and Phase II is currently under construction.
