Abstract

The invention discloses a method for improving the cellular transmission model considering intersection signal control. The method includes: S1 cell length variable setting; S2 area cell division method design; S3 cell transmission model simulation granularity into individual vehicles; S4 signal control intersection cell transmission flow rate dynamic adjustment to realize intersection signal control The establishment of the cellular transport model in the environment. Compared with the traditional cellular transmission model, the present invention can be applied to urban roads with diversified road sections and signal-controlled intersections, and can reproduce the queuing formation and dissipation process of the traffic flow at the intersection. At the same time, compared with the traditional simulation model, This method can further improve the simulation speed and provide the manager with the simulation effect of the scheme in time, helping the manager to make a scientific and reasonable decision.

Description

technical field

[0001] The invention relates to the technical field of traffic simulation, in particular to a method for improving a cell transmission model considering intersection signal control. Background technique

[0002] At present, traffic congestion has become a common problem faced by large and medium-sized cities all over the world, and the losses caused by congestion remain high every year. Although a lot of research results have been obtained in the aspect of congestion control, its implementation effect is not ideal. Facts show that only by deeply understanding the nature of various traffic phenomena and exploring the internal mechanism of traffic flow evolution can scientific and effective control and management measures be put forward. Therefore, an improved method of the Cell Transmission Model (CTM) considering the intersection signal control is proposed, and the improved Cell Transmission Model is used to reproduce the queuing formation and dissipation pr...
