5. Advanced Traveler Information System for Indian Cities

Advanced Traveler Information Systems (ATIS) is defined as systems that acquire, analyze, and present information to assist surface transportation travellers in moving from a starting location (origin) to their desired destination. ATIS may operate through information supplied entirely within the vehicle (autonomous system) or it can also use data supplied by the traffic management centres. Autonomous systems utilize vehicle position determination and stored map data. The use of data from the traffic control centre assists the driver in knowing the current status of the traffic in real time, and to make intelligent decisions. The information will include locations of incidents, weather and road conditions, optimal routes, recommended speeds, and lane restrictions.

Through the applications of advanced information and communication technologies, Advanced Traveler Information Systems (ATIS) offer the potential and ability to provide better solutions for urban traffic. The potential benefits to travelers include: reduced congestion, air-pollution, and energy consumption, and increased safety, efficiency and management of capacity.

The project focuses on the Personal Traveler Information Systems and Variable Message Signs which are likely to be most relevant to urban traffic scenarios in India. The Advanced Traveller Information System for Indian Cities was developed by IIT Madras with the support of C-DAC Thiruvananthapuram.
