In fact, these design ideas ignore an important prerequisite for the coordinated control of social traffic flow and bus flow, that is, how to ensure that the time of social traffic flow and bus flow arriving at the downstream intersection is synchronized, so they often lose sight of the other, and cannot ensure that the social traffic flow and bus flow are synchronized. Traffic flow at the same time to obtain better signal coordination control effect
[0004] At present, research at home and abroad mainly focuses on the mixed traffic flow model of social vehicle flow and bus flow, but there is little research on the synchronization of social vehicle flow and bus flow. Time design method has very important practical significance

Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0030] It is known that adjacent intersection 1 and intersection 2, and the lane allocation of the entrance lanes of the upstream intersection 1 to be synchronized traffic flow are shown in the attached figure 2 As shown, the distance from the stop line at the west entrance of upstream intersection 1 to the section at the east exit is 30m, the distance from the stop line at the north entrance at upstream intersection 1 to the section at the east exit is 50m, and the distance from the section at the east exit at upstream intersection 1 to the section at the downstream intersection The distance of the parking line at the west entrance of Exit 2 is 550m; the average driving speed of social vehicles is 50km / h, the average driving speed of public transport vehicles is 30km / h,...

The invention discloses a crossroad signal time-allocation designing method for the synchronization of the private car flows and the bus flows. The method comprises: numbering the car flows about to undergo synchronization design; determining the synchronization combinations of all the private car flows with the bus flows; based on the car flow combinations, equalizing the traffic quantities and ranking the synchronization combinations of the car flows; and according to the ranked synchronization combinations of the car flows, determining the crossroad signal time-allocation parameters. With the designing method, it is possible to realize the synchronization control of private car flows and bus flows so as to ensure that the private car flows and the bus flows obtain the relatively good signal coordination control effect at the same time and to guarantee for the maximal coordination optimization and control economy.
Description
technical field [0001] The invention belongs to the field of traffic signal control, in particular to an intersection signal timing design method oriented to the synchronization of social traffic flow and bus flow. Background technique [0002] At present, many cities in China are actively implementing signal coordination and optimization design in the traffic control and management of arterial roads, with the purpose of reducing the delay time and parking times of traffic flow. For the signal coordination optimization design of social traffic flow and bus flow, different urban traffic management departments have different considerations. Some cities have carried out green wave coordinated signal timing design mainly for social traffic flow. These signal timing design schemes can reduce the delay time and parking times of social vehicles at intersections, but make public vehicles encounter red wave bands at downstream intersections. , greatly reducing the service level and ...
