Advanced Traveler [r~format~on Systems (ATIS) under the intelligent Vehicle Highway Systems (IVHS) context require efficient information retrieval and updating in a dynamic environment and at different geographical scales. Some problems in ATIS can be solved based on the functionalities provided by GIS systems. However, extra requirements such as realtime response are not readily met in existing GIS systems. We investigate the use of GIS-based systems for applications in ATIS and we propose a
