Although there are many similar studies and explorations related to the traffic capacity of waiting areas in China, there is no unified traffic capacity calculation standard for domestic traffic characteristics. In traffic design and evaluation, this will inevitably increase the difference between calculation results and actual conditions. degree of inconsistency

Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0032] Such as figure 1 As shown, the method for obtaining the traffic capacity of the road intersection waiting area provided by the embodiment of the present invention includes the following steps:
[0033] 1) Collect the type of waiting area at the intersection, the length of the waiting area, and the timing information of traffic signals. The timing information of traffic signals includes green light time and control cycle.
[0034] During the data collection, the influencing factors of the traffic capacity of various waiting areas were analyzed and studied, and the corresponding...

The invention relates to a method for obtaining the traffic capacity of a road intersection vehicle-waiting area. The method comprises the steps that (1) the type of the road intersection vehicle-waiting area, the length of the vehicle-waiting area and traffic signal timing information are collected; (2) the corresponding capacity of the vehicle-waiting area is calculated according to the length of the vehicle-waiting area; (3) the corresponding start loss time is calculated according to the type and capacity of the vehicle-waiting area; (4) the traffic capacity of the vehicle-waiting area is calculated according to the start loss time, the capacity of the vehicle-waiting area and the traffic signal timing information. Compared with the prior art, the method has the advantages that calculation is convenient, and accuracy is high.
Description
technical field [0001] The invention relates to the field of traffic control, in particular to a method for acquiring the traffic capacity of a waiting area at a road intersection. Background technique [0002] Nowadays, most intersections are equipped with waiting areas. The purpose of the waiting area is to release more internal space at the intersection and increase the capacity of the entrance road without affecting the traffic, so as to relieve the traffic pressure and improve the traffic efficiency. Although there are many similar studies and explorations related to the traffic capacity of waiting areas in China, there is no unified traffic capacity calculation standard for domestic traffic characteristics. In traffic design and evaluation, this will inevitably increase the difference between calculation results and actual conditions. The extent to which the situation does not match. [0003] Therefore, a set of calculation methods specifically for the capacity of the...
