Embodiment Construction
[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] Such as figure 1 As shown, a method for estimating OD position and OD matrix of traffic flow, specifically includes the following steps:
[0033] S1, Obtain historical traffic flow: select a group of road networks consisting of N intersections, each intersection is connected by n road sections, N and n are natural numbers, and obtain historical traffic flow data of the road network within 24 hours S.
[0034] S2, cluster analysis: based on the historical traffic flow data S of the highway network within 24 hours, the traffic flow data of each road section constitutes a characteristic data group, and cluster analysis is performed on the characteristic data group to obtain k classes and k The traffic flow in different time periods is denoted as S 1 to S k , k is a natural number and 1≤k≤24. The K-means clustering algorithm can be use...
