Intelligent Vehicle and Highway Systems (IVHS) and Advanced Transport Telematics are the names which have been used in America and Europe, respectively, to describe the application of information, communications, data acquisition, and control system technologies in surface transportation. This paper discusses efforts to define the vision and future of these technologies. IVHS will help support more sustainable transportation system development only if it is redefined as part of a broader vision. US DOTS progress in moving the IVHS program towards a broader ITS framework and in placing greater emphasis on the environmental and societal impacts of these and other transportation technologies and policies is encouraging. |
