Road traffic capacity control method

Abstract

The invention provides a road traffic capacity control method, including the following steps: S1, collecting road segment traffic volume information between two adjacent intersections, and determiningaverage vehicle speed V1 of the road segment; S2, collecting intersection length D and traffic flow information q2 of the downstream intersection in the two adjacent intersections, and determining average vehicle speed V2 of the downstream intersection; S3, determining real-time traffic volume q1 between the two adjacent intersections and maximum traffic capacity ql between the two adjacent intersections according to the information collected in the Steps S1 and S2; and S4, comparing the traffic capacity q1 with the maximum traffic capacity ql, and adjusting the traffic volume between the adjacent intersections according to a comparison result. The traffic capacity of an intersection and adjacent intersections can be accurately assessed, and reasonable traffic control measures can be taken according to an assessment result.

Description

technical field [0001] The invention relates to a traffic control method, in particular to a road traffic capacity control method. Background technique [0002] With the development of society, the number of cars has gradually increased. However, the increase in the number of roads used for driving cars is far behind the increase in car ownership, which has caused increasingly serious congestion in modern urban roads. However, urban roads Another problem of congestion is that the road traffic capacity has not been reasonably controlled. This is due to the fact that there are many intersections in the city, and the driving speed between adjacent intersections is different from that at the intersection. Often the speed at intersections is lower than the speed of road sections between adjacent intersections. If the traffic capacity is not controlled, it will cause the vehicles at downstream intersections to overflow to the upstream, thereby forming serious congestion. In the pr...

[0002] With the development of society, the number of cars has gradually increased. However, the increase in the number of roads used for driving cars is far behind the increase in car ownership, which has caused increasingly serious congestion in modern urban roads. However, urban roads Another problem of congestion is that the road traffic capacity has not been reasonably controlled. This is due to the fact that there are many intersections in the city, and the driving speed between adjacent intersections is different from that at the intersection. Often the speed at intersections is lower than the speed of road sections between adjacent intersections. If the traffic capacity is not controlled, it will cause the vehicles at downstream intersections to overflow to the upstream, thereby forming serious congestion. In the prior art, there is also There is no effective means to solve the above-mentioned technical problems
