Problems solved by technology

[0006] However, at present, the lost time of green lights mainly depends on the staff based on the experience accumulated in their work, through artificial observation of intersections, and artificially summarizing the lost time of green lights. In line with the actual situation, the timing scheme adjusted according to the lost time of green lights still cannot improve the traffic efficiency of road intersections

Embodiment Construction

[0088] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0089] figure 1 is a flow chart of a method for acquiring lost time according to an exemplary embodiment, as shown in figure 1 As shown, the method is used in an electronic device, and the electronic device includes a terminal or a server, and the method includes the following steps.

[0090] In step S101, the first actual number of vehicles passing through the lane within the preset allowed passing time is acquired;

[0091] In the traffic signal lights at intersections, the green light, the yellow light and the red light are usually turned on sequentially, and a cycle is formed from the start of the green light to the start of the next green light.

[0092] When the green light in the traffic signal ...

Abstract

The embodiment of the invention provides a loss duration acquisition method and device. Manual participation is not needed in the process of obtaining the loss duration, therefore, the subjective influence of people is avoided, labor cost can be saved, the data obtained by use in the whole process is obtained based on historical actual conditions, the used data is consistent with the actual situation, so that the obtained loss duration is more consistent with the actual situation, the timing plan can be optimized and adjusted more accurately and reasonably according to the determined loss duration, and the traffic efficiency of the road intersection is improved.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a method and device for acquiring lost time. Background technique [0002] With the increasing number of cars, the traffic management department generally adopts the orderly transformation of traffic lights to regulate the traffic order at the intersections with large urban traffic volume. Traffic lights include green lights, yellow lights, and red lights. [0003] The current signal light timing scheme cannot adapt to the current traffic flow requirements in real time and efficiently. In practical applications, the traffic efficiency of road intersections is often not high. Green light but no car needs to pass, wasting the time of green light. [0004] Therefore, it is necessary to evaluate the timing of signal lights and optimize the timing scheme to improve the traffic efficiency of road intersections. [0005] Among them, the green light loss t...
