In this project, an information system is designed for commuters of Brihanmumbai Electric Supply and Transport undertaking (BEST) which provides bus service in Mumbai city. In the process, the current information system of BEST was studied. Also, information system of bus services of different cities was studied to understand new transit technologies. Several regular and non-regular commuters were observed and interviewed and hours of observations were done at different bus stops and in buses to identify their needs and problems. Also, a new pattern of commuting amongst the commuters in the city is identified. On the basis of these background studies, a mobile phone based information system along with indicators at bus stops and inside buses, a telephone helpline service and a website is proposed. Using this solution, users could plan their journey by knowing information of the nearest bus stops or any bus stop; bus routes, fares, arrival time and crowd in the buses arriving at any bus stop. Users could get this dynamic information; anywhere and at any time during the journey. This information would equip the users to get all the needed information, before beginning the journey, enabling them to arrive at the bus stop just in time to catch the bus. The design would cater, both regular as well non-regular commuters, by providing the necessary real time data at every stage of the journey.
