It points out how difficult it is for a person to make a decision to travel by transit under lack of information, citing typical scenarios of transit trips. It also defines the functions and elements of an Intelligent Transit Mobility System (ITMS). ITMS requires four main elements. They are: information collection, central processor, software for decision aid algorithms, and communications and information dissemination medium. The study further discusses the issues which are non-technical but important for planning and implementation. The issues include coordination of participating agencies, roles of different parties, financial responsibility, and implications to the life style and general travel habits in urban areas.95
