Embodiment

[0114] 1. Selection of urban target road network:

[0115] A certain local area in the central urban area of ​​Shanghai is selected as the research object, and it is abstracted into a corresponding self-organizing virtual network.

[0116] 2. Set the necessary scenarios for the simulation:

[0117] 1) For each intersection in the entire area, its physical properties such as length and number of lanes are fixed, and the parameters used to characterize the properties of each branch of the intersection are set as global variables in each sub-module.

[0118] 2) As a simulation of an open area, the traffic flow enters the system from the boundary area, and the lateral flow and longitudinal flow are set at the same time, which are respectively:

[0119] Horizontal flow = 2000 vehicles / hour, longitudinal flow = 1400 vehicles / hour

[0120] 3) As a non-boundary area, its input and output are completely carried out in accordance with the previous related algorithms, so that the traff...

Abstract

The invention relates to a method for structuring city traffic signal automatically organize rule based on fluid dynamics in the field of traffic project technology. The invention uses city traffic signal control system as traffic network processing, each intercross as intelligent body with auto collecting and processing function; each intercross possesses two suits of cell salve robot to achieve the dynamic resolution of each intercross traffic signal control; it uses the resemblance between traffic flow and fluid flow to introduce fluid dynamics to establish the balance model of traffic flow and sets city traffic signal automatically organize and control rule based on four phases switching at the same time; it sets traffic intercross phase quoting rule to achieve the real time resolution of traffic system signal model.

Description

technical field [0001] The invention relates to a control method in the technical field of transportation, in particular to a method for constructing self-organizing rules of urban traffic signals based on fluid dynamics. Background technique [0002] From the perspective of urban traffic signal control methods and application technologies, the current background technologies of urban traffic signal control mainly include simplified methods from the perspective of large systems; intelligent methods from the perspective of artificial intelligence; and complexity methods from the perspective of self-organization. The simplification method based on the view of the large system has many factors to consider, the calculation amount is too large, the dimension is high, it is difficult to realize real-time control, and there is a problem of abandoning the essence of the complexity of urban vehicle flow traffic control. The actual application effect Very unsatisfactory. In the traff...
