Embodiment Construction
[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] refer to figure 1 , a public cycle and intersection cycle calculation method oriented to the coordinated control of traffic sub-area, mainly divided into three levels: dynamic traffic network modeling module 103, road network node importance calculation and sorting module 102, public signal cycle of traffic sub-area And intersection signal cycle calculation module 101. The three parts have a level-by-level support relationship, that is, the dynamic road network model provides a platform for road network performance calculation and importance calculation, and the order of importance provides a basis for the selection of public cycles.
[0036] refer to figure 2 , the road network topology data and traffic flow monitoring data 204 provide data support for the dynamic road network modeling 203; on top of the dynamic road networ...
