浮动车交通信息采集系统

Traffic Data Collection based on Probe Vehicle

浮动车交通信息系统是伴随着ITS新技术的应用而在近几年发展起来的新型交通流信息采集技术,它可以直接和方便地测得可靠、准确的车辆行驶速度、路段行程时间等参数。该系统作为一种重要的交通信息采集方法,可以弥补现有传统交通信息采集技术存在的数据不完全、数据量不足、数据质量差等问题,对我国交通信息采集工作具有很好的现实意义。

The floating vehicle traffic data collecting system is a new kind of traffic data collecting technology which has been developed with the application of ITS new technology in the recent years. It could directly and conveniently detect reliable and accurate parameters, including vehicle travel velocity and path trip time. This system, an important method for collecting traffic data, can complement the deficiencies existing in the traditional traffic data collecting methods, which involve the insufficient data quantity, the low data capacity and the poor data quality. As a result, this system is very significant for the traffic data management field in our country.
