Problems solved by technology

[0004] For traffic at crossroads, the design of the above-mentioned traffic signal lights is already the most "smart" configuration among the signal lights at crossroads that are often encountered in daily life. When such situations occur, it is easy to cause pedestrians or vehicles to fail to pass normally and safely, and even cause traffic accidents.

Embodiment 1

[0045] This embodiment provides a method for intelligent traffic control at urban crossroads, such as figure 1 and figure 2 shown, including the following steps:

[0046] S1. White LED light strips are arranged and laid on the sidewalk of the intersection in sequence, as a zebra crossing on the sidewalk at the intersection. The controller controls the pedestrian signal lights at both ends of the sidewalk at the intersection to act synchronously with the switch of the white LED light strip; specifically, during the time period when pedestrians are allowed to pass, The controller controls the pedestrian signal light to be green, and at the same time controls the white LED light strip to start to emit white light; during the time when pedestrians are prohibited from passing, the controller controls the pedestrian signal light to be red, and at the same time controls the white LED light strip to turn off.

[0047] S2. Use colored LED light groups to lay on the road surface of th...

Embodiment 2

[0050] Further improvement on the basis of Embodiment 1, further including step S3, that is, the linkage control step of the roadway and the sidewalk: during the time period when vehicles are allowed to pass:

[0051] By comparing the detection data of the pressure sensor set on the sidewalk at the intersection with the set threshold, it is judged whether there is a pedestrian passing; by comparing the detection data of the pressure sensor set on the roadway of the stone intersection with the set threshold, it is judged whether there is Vehicles pass; based on the above judgment results, the controller links the white LED light strips on the sidewalk and the colored LED lights on the relevant roadway to act synchronously to guide vehicles and pedestrians to pass in an orderly manner. The specific implementation method is as follows:

[0052] S31. Collect the detection data of the pressure sensor buried on the sidewalk at the intersection, and collect the detection data of the ...

Embodiment 3

[0058] This embodiment provides an intelligent traffic control system at an urban intersection, which is used to implement the intelligent traffic control method at an urban intersection provided in Embodiment 2. Including white LED light strips, colored LED light groups, white LED light arrows, three-dimensional projection equipment, signal light conversion countdown timer and controller:

[0059] The white LED light strips are used to be arranged and laid on the sidewalk at the intersection in sequence, as a zebra crossing on the sidewalk at the intersection.

[0060] The white LED light arrow is used to set up the roadway and sidewalk at the intersection, and is controlled by the controller. Arrow points are used to indicate the allowed travel direction of vehicles and pedestrians; on the sidewalk, white LED light arrows and white LED light strips are distributed at intervals.

[0061] The three-dimensional projection equipment is used to set up at both ends of the zebra c...

Abstract

The invention discloses an urban crossroad intelligent traffic control method and system, and the method comprises the following steps: S1, sequentially arranging and laying white LED lamp strips on a crossroad sidewalk as crossroad sidewalk zebra crossings, and controlling pedestrian signal lamps at the two ends of the crossroad sidewalk and the switches of the white LED lamp strips to act synchronously by a controller; s2, a colored LED lamp set is laid on the road surface of a crossroad roadway, and color development of the road surface of the roadway is achieved; and the controller controls the color development of the colored LED lamps on the corresponding roadways of the crossroad and the synchronous action of the crossroad traffic signal lamps. According to the invention, safe and orderly passing of pedestrians and vehicles at the crossroad is guaranteed, the passing efficiency and safety are improved, and traffic jam or traffic accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of urban road traffic, in particular to an intelligent traffic control method and system at urban intersections. Background technique [0002] At present, the traffic volume of urban roads in some large and medium-sized cities has reached a relatively high level, and with the development of the economy, the number of cars in each city is still growing rapidly. Some cities with congested urban roads have begun to take measures to reduce traffic volume, such as restrictions on purchases, restrictions on driving, and increased urban road construction. These measures have achieved certain results, but it is also a common impression that urban roads are becoming more and more congested. In order to alleviate the problem of urban road congestion, deep excavation should be carried out from all levels of the traffic system. Most of the aforementioned measures belong to limiting "demand" - slowing down the increase i...
