The working report presents a study of the travel to work in the South Corridor of the Oslo region in June 1996. The aim of the project has been to reveal effects of the land use and transport planning upon the use of public transport to work. The travel behaviour in the South Corridor is a result of both accessibility by public transport and accessibility by car. A location policy and a development of the public transport system according to the principals of the Dutch ABC-system, will contribute to a growth in work trips by public transport. The working report presents a proposal for an ABC-system for the South Corridor.
