Computer-aided Systems in Public Transport

This proceedings volume consists of selected papers presented at the Ninth Int- national Conference on Computer-Aided Scheduling of Public Transport (CASPT 2004), which was held at the Hilton San Diego Resort and Conference Center in San Diego, California, USA, from August 9-11, 2004. The CASPT 2004 conference is the continuation of a series of international workshops and conferences prese- ing recent research and progress in computer-aided scheduling in public transport. Previous workshops and conferences were held in: • Chicago (1975) • Leeds (1980) • Montreal (1983 and 1990) • Hamburg (1987) • Lisbon (1993) • Cambridge, Mass. (1997) 1 • Berlin (2000) 1 While there were no formal proceedings for the ?rst workshop (only pre-prints were d- tributedtoparticipants),thesubsequentworkshopsandconferenceswerewelldocumented: Wren, A.
