Embodiment Construction

[0077] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0078] It should be noted that when a component is referred to as being "mounted on" another component, it can be directly on the other component or there may also be an intervening component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a co-existing centered component. When a component is said to be "fixed" to another component, it may be directly fixe...

Abstract

The invention discloses a method for evaluating traffic efficiency in a phase sequence at an intersection and a method for evaluating traffic. The method for evaluating the traffic efficiency of the intersection phase sequence includes: calculating the traffic efficiency of the intersection; calculating the traffic efficiency early warning coefficient of the intersection according to the traffic efficiency of the intersection: performing early warning of the traffic efficiency of the intersection according to the early warning coefficient of the traffic efficiency of the intersection: according to the early warning coefficient of the traffic efficiency of the intersection, and different traffic saturation. Compared with the early warning coefficient of phase traffic efficiency of degree, the corresponding early warning level is obtained. The present invention calculates the vehicle traffic efficiency by synthesizing the vehicle traffic efficiency and traffic energy consumption, and provides the intersection phase sequence evaluation criterion, which provides a basis for the intersection phase sequence design and evaluation. The above-mentioned method can improve the efficiency of phase-sequence traffic at the intersection, save the traffic time and reduce the energy consumption, make up for the blank of the existing technology, and facilitate energy saving and environmental protection.

Description

technical field [0001] The invention relates to a benefit evaluation method and a traffic evaluation method, in particular to an intersection phase-sequence traffic benefit evaluation method and a traffic evaluation method using the intersection phase-sequence traffic benefit evaluation method. Background technique [0002] At present, the phase sequence design of intersections generally mainly includes two-way straight and left-turn traffic, and one-way straight and left-turn. The phase sequence timing generally adopts the Webster timing method. With the increase of urban motor vehicles, the traditional phase sequence design and phase sequence timing are not adjusted according to the actual traffic flow at the intersection, resulting in more and more serious congestion at the intersection. [0003] At present, in order to further improve the efficiency of vehicular traffic at intersections, city management departments have proposed variable lanes and adjustable phase sequen...
