Realization of ITS applications through mapping technologies: A survey of advanced traveler information systems

ITS applications throughout the United States use a variety of mapping technologies to efficiently relay traffic information to both traffic agents and the general public. This paper describes the findings of a nationwide survey of the mapping approaches taken by traveler information websites. The technologies used within the Oklahoma ITS architecture are also presented within the context of this survey. The mapping technologies discussed include ArcGIS, MapServer, HTML-based techniques, Google Maps, Bing Maps, and OpenLayers. The tradeoffs that would be considered when evaluating the use of mapping technologies in new or existing ITS applications are presented for comparison.
