Feasibilities and Challenges of Probe Technologies for Real-Time Traffic Data Collection
Probe vehicles are playing an increasingly important role in the field of ITS, and showing high value for various applications over the last decade. Recent advances of probe vehicle technologies in Japan are explored by reviewing the existing studies in both academic fields and ITS practice projects. The methods of data collection and data processing are summarized, which is followed by a brief review of recent attentions and the possible solutions. In order to enhance the feasibility of probe vehicles for real-time traffic surveillance through the entire road network, this paper tries to identify some unresolved issues that may have impacts on the reliability of obtained real-time traffic data and the efficiency of data collection. Four addressed issues include: error propagation of map matching, the bias in link travel time estimation, lower accuracy of link travel time measurement through infrequent observations, and the efficiency in area coverage.
