The invention relates to a road network traffic flow deduction method based on a highway toll collection system. The method comprises the following steps: 1) collecting vehicle passing data of a highway toll collection system; 2) constructing a road network topological structure; 3) calculating the traffic flow of each road section in the road network according to the collected vehicle passing data; 4) calibrating and optimizing the traffic flow deduction model to improve the accuracy and precision of prediction; 5) deducing the center point, density and radius information of the cluster to a corresponding road section based on a road network and a traffic flow theory in combination with a vehicle passing rule, and realizing spatial relation mapping of the cluster and the road section; and 6) judging the road section to which the cluster belongs through the spatial relationship, and further deducing the real-time traffic flow of the road section. By modeling and analyzing the road network, the traffic flow deduction of each road section in the road network is realized, the real-time traffic flow on the road can be accurately predicted, and the efficient and real-time traffic flow deduction is realized.

    本发明涉及一种基于高速公路收费系统的路网交通流量推演方法。该方法包括以下步骤:1)收集高速公路收费系统的车辆通行数据;2)构建路网拓扑结构;3)根据收集到的车辆通行数据,计算路网中各路段的交通流量;4)校准和优化交通流量推演模型,以提高预测的准确性和精度;5)基于道路网络和交通流理论,结合车辆通行规律,推演簇的中心点、密度和半径信息到对应的道路段上,实现簇与道路段的空间关系映射;6)通过空间关系判断簇所属的道路段,进而推演出道路段的实时交通流量。本发明通过对道路网络的建模和分析,实现对路网中各路段的交通流量推演,能够准确预测道路上的实时交通流量,实现高效、实时的交通流量推演。
