| 摘 要： | 交通道路的单向限行状态识别可以为社会公众提供及时准确的路网限行信息，提高公众出行效率，提升动态交通信息服务水平。提出了一种基于浮动车数据的道路单向限行状态动态识别算法。该算法首先获取地图线要素信息，并进行空间信息网格对交通道路的投影匹配预处理，实现海量浮动车数据的快速匹配；然后分析各道路的浮动车数据方向信息的统计特性，对其进行双阈值信息过滤和方向信息过滤处理，以动态提取交通道路的单向限行状态信息。经实际路网测试验证，该算法可有效识别道路的单向限行状态信息。 |

| Abstract: | The identification of one-way road state can provide relevant information of road network to the public timely and accurately, improve the efficiency of public travel, and enhance the service level of dynamic traffic information. This paper presented a dynamic identification algorithm of one-way road state based on Floating Car Data (FCD). Firstly the line feature information of maps was got, and the matching of spatial information grid with the traffic roads was pretreated to achieve fast matching for massive FCD; Then statistical characteristics of FCD direction information was analyzed to filter dual-threshold information and direction information; Finally one-way road state information was got dynamically. The actual road network tests show the algorithm can identify one-way road state information effectively. |
| Keywords: | Floating Car Data (FCD) one-way road identification spatial grid dual-threshold information filtering |
