An account is given of Munich's electronic timetable information system (EFA) developed to help passengers decide on the optimum route between locations in a dense transport network. Using data stored for timetable production, a three-dimensional route search procedure is carried out and a response provided in 5 seconds. For each journey the system provides departure time and point, number and direction of line, any changes, amount of walking involved, destination point, arrival time and fares for adults and children. The timetable system is available on videotext, by telephone and at a number of public information terminals. The system has a number of advantages for disabled people including its availability in the home. Further use can be made by specifying a route with least changes, no stairs or no roads to be crossed. It is also possible to analyse which routes the disabled want to use and improve them.
