With the development of the information and communication technology, a probe car system that collects traffic information from the vehicles cruising on the road network is attracting attention. Particularly, probe-vehicle system has many advantages ; e.g. the system can collect traffic information from all road sections where the probe-vehicle cruises, obtain various information such as vehicular acceleration and cruising route, and so on. However, it is necessary for implementation of wide-area probe-vehicle system to solve a lot of problems ; presentation of usability as traffic information and establishment of method for utilization and for effectively gathering information and provision of information. This research developed and investigated several technologies in response to above problems.First, to present a usability of probe-vehicle data as traffic intonation, the route guide system using the probe-vehicle data was developed. The result of competitive experiment with the nav … More igation systems in the market showed the superiority of utilization of probe-vehicle data. In addition, the effect of route guidance of the developed system was shown from the route guidance experiment in commuting situation. Second, various methods for effective utilization of probe-vehicle data were established. Especially, this research showed that probe-vehicle data enables us to analyze drivers' route dots behavior to the last detail, to vent/ the effects of coordinated signal control, to identify the common site of traffic accidents and the probe-vehicle data can be utilized for updating dynamic O-D matrices. Furthermore, this research examined that the efficiency improvement of the data collection. After clarifying that the probe data collection frequency has a significant influence on the implementation of the large scale probe system, several techniques for using infrequent probe-vehicle data were developed and the optimal location .problem of probe-vehicle was studied. A lot of problem for the implementation of a wide-area probe-vehicle system were solved by executing this research. Less

随着信息和通信技术的开发，从公路网络上巡游的车辆收集交通信息的探测器系统引起了人们的关注。特别是，探针系统具有许多优势。例如该系统可以从探测器巡航的所有路段收集交通信息，获取各种信息，例如车辆加速和巡航路线等。但是，有必要实施大区域探针系统来解决许多问题。呈现可用性作为流量信息，并建立利用方法以及有效收集信息和提供信息。这项研究开发并研究了几种针对上述问题的技术。首先，为了呈现探针 - 车辆数据作为交通语调的可用性，开发了使用探针 - 车辆数据的路线指南系统。与NAV的竞争性实验的结果…更多的市场中的ITAD系统表明了探针 - 车辆数据的优势。此外，从犯罪情况的路线指导实验中显示了开发系统的路线指导的效果。其次，建立了各种有效利用探针数据数据的方法。尤其是，这项研究表明，探针 - 车辆数据使我们能够将驱动程序的路线点行为分析到最后一个细节，发泄/对协调的信号控制的影响，以识别交通事故的常见部位，并且可以利用探针车辆数据来更新动态o-d材料。此外，这项研究研究了数据收集的效率提高。在澄清探针数据收集频率对大规模探针系统的实现具有重大影响后，开发了几种用于使用不频繁的探针 - 车辆数据的技术，并且研究了最佳位置。通过执行这项研究解决了实施大区域探针系统的许多问题。较少的
