Abstract

In France, Germany and Spain, the availability of computer-generated itineraries to travellers in the street is still very limited, though growing slowly. Although many French towns have an effective passenger information system via Minitel, which will calculate itineraries, this is available only from the home. The vast majority of decisions about routes for journeys by urban public transport are still made using the traditional forms of spatial information abundantly displayed at bus stops and in vehicles: usually a map of the network and diagrammatic maps of individual bus or underground lines. Unfortunately a map of the whole network is often too complicated to yield the desired information easily. Alternatively the traveller may have the difficult task of comparing several diagrammatic maps of the individual lines departing from that bus stop, none of which alone can answer his spatial query: which bus lines, if any, go to my destination? The priority for the application of the computer should be the use of a geographic information system to generate automatically two types of less-complicated map. The 'stop-specific route map' shows on one piece of paper the routes of all buses from that stop, excluding of course the portions before the stop. The 'zone map' shows only the bus lines which serve a specific limited zone of the city, including at a reduced scale the portions extending out to their various destinations beyond the limits of the zone itself.
