| 摘要： | This paper presents the results of the evaluation of the CAPITAL ITS Operational Test and Demonstration Project. Focus of the project was assessing the viability of using cellular-based traffic probes as a wide area vehicular traffic surveillance technique in the Washington D.C. metropolitan area. Specifically, the project had three objectives: 1) to determine if cellular telephones provide a cost effective means of wide area traffic surveillance; 2) to determine if this type of information can be effectively integrated into a real- time area-wide traffic system management system; and, 3) to determine if packet data transmission over a cellular telephone communications network provides an effective means of disseminating real-time area- wide traffic information. Results were promising, however, the project did not produce the level of accuracy as hoped for due to several factors, including: geolocation accuracy, speed estimation algorithm, and incident detection algorithm. |
