ASSESSMENT OF EXISTING METHODS OF "TRAVEL TIME" ACQUISITION AND MEASUREMENT

Many techniques, devices, systems, and services involved in intelligent transportation systems deployment are based on obtaining reliable traffic data coping with real time or travel time estimations. This paper: 1) defines and quantifies the type of data needed to have good coverage of a network and obtain accurate travel times for at least 90 percent of the trips; 2) assesses the technologies in use or in a development phase to achieve the results of collecting real-time travel times information; and 3) outlines the most promising results from a cost-effectiveness perspective. The paper will consider also the push and pull factors involved in the industrial development of technologies and systems to collect and calibrate real-time travel times acquisition. France will remain the focus for the evaluation of technical and business implementation, but the scientific aspects of this implementation will remain on a global level, with applications for any geographic context.
