Embodiment 1

[0033] figure 1 A detailed schematic diagram of a signal light control process provided for an embodiment of the invention, the process includes the following steps:

[0034] S101: Determine whether a pedestrian crossing request is received after the start of the branch straight phase in the previous cycle and before the start of the branch straight phase in this cycle; wherein, each signal light at the same intersection in a cycle includes a set number of phases, The signal light of the corresponding color in each phase lights up for a preset duration. If yes, execute S102; if not, execute S103.

[0035] The signal light control method provided by the embodiment of the present invention is applied to an electronic device, and the electronic device may be a smart device such as a PC or a local server.

[0036] In order to adapt to road conditions, in the embodiment of the present invention, when a pedestrian on a branch road needs to cross the street, a pedestrian crossing r...

Embodiment 2

[0046] In order to improve the traffic efficiency of the intersection, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, if the length of the straight-going phase of the branch in this cycle is extended to the first preset duration, the method includes:

[0047] Determine the extension duration of the straight-going phase of the branch in this cycle;

[0048] Compressing the duration of each target phase in the current cycle, wherein the total compressed duration of each target phase is equal to the extended duration.

[0049] When the straight-going phase of the branch in this cycle changes, in order to ensure that other cycles are not affected, the green wave coordination of the main road can be carried out normally. In the embodiment of the present invention, when the duration of the straight-going phase of the branch is extended in this cycle, it can be Compress the duration of each target phase in this cycle, so as to ensure that...

Embodiment 3

[0061] In order to accurately determine the compressed duration of each target phase, on the basis of the above embodiments, in the embodiment of the present invention, according to the number of the target phases in this cycle and the extended duration, determine each The compressed duration of the target phase includes:

[0062] If the number of the target phase in this period is one, then determine that the extended duration is the compressed duration of the target phase;

[0063] If the number of the target phases in this period is at least two, then determine the division ratio of the extended duration according to the stored compressible duration of each target phase, and determine according to the division ratio and the extension time The length of time each of said target phases is compressed.

[0064] In order to accurately determine the compressed duration of each target phase, in the embodiment of the present invention, it may be determined according to the number ...

Abstract

The embodiment of the invention discloses a signal lamp control method and device, equipment and a medium, which are used for solving the problems that in the prior art, safe crossing of pedestrians cannot be balanced, and the passing efficiency of crossings is low. In the embodiment of the invention, if the pedestrian crossing request is received after the branch straight-going phase in the previous period starts and before the branch straight-going phase in the current period starts, the straight-going phase duration of the branch in the current period is prolonged, and if the pedestrian crossing request is not received, the straight-going phase duration of the branch in the current period is kept unchanged; according to whether the branch has the pedestrian crossing request or not, the straight-going phase duration of the branch is adjusted, so that the adjusted straight-going phase duration of the branch in the embodiment of the invention can well adapt to the traffic condition of the branch, thereby ensuring that the pedestrian safely crosses the street when the pedestrian crossing request is received, and ensuring the traffic efficiency of the intersection when the pedestrian crossing request is not received The is ensured.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a signal lamp control method, device, equipment and medium. Background technique [0002] In recent years, with the development of urbanization and the rapid increase of car ownership, urban traffic problems such as traffic congestion and traffic accidents between people and vehicles have become increasingly serious. At some intersections with clear main branches, the traffic efficiency in the direction of the main road and the safety of pedestrian crossing in the direction of the branch road compete with each other. How to improve the traffic efficiency of road vehicles and ensure the safety of pedestrians crossing the street is of great significance to the intelligent traffic control system of the city. [0003] The traditional timing scheme of fixed signal cycle, in some intersections with clear main road and branch roads, in order to ensure the safety of pedestrians cr...
