Problems solved by technology

Although relevant policies have been issued at present, motor vehicles must give way to pedestrians when passing a pedestrian crosswalk, but many times pedestrians are in the blind spot of the vehicle driver's vision, such as pedestrians are blocked by the surrounding environment when they are on the side of the road or between two-way lanes, and pedestrians have already left. Even if the driver consciously reduces the speed and faces the sudden appearance of pedestrians, there is no guarantee that he can react in time and avoid pedestrians when he is blocked by the front or side vehicles when entering the crosswalk. Pedestrian crosswalks at intersections or road sections without signal lights are convenient for pedestrians to cross the street. , It also increases the probability of accidents between pedestrians and motor vehicles, and there is no means or method to pre-protect the safety of pedestrians. Sometimes, the crosswalk becomes a more dangerous path for pedestrians

Embodiment

[0026] In order to build a roadside system that reminds passing vehicles when pedestrians cross the street, first set the points: Pedestrian detection trigger unit setting: a roadside system that reminds passing vehicles when pedestrians cross the street is mainly based on the Levision fusion all-in-one machine to detect pedestrians crossing the street There is information, and the LORA communication mode is used to realize the pop-up of early warning information on the upper screen, so as to remind passing vehicles to avoid pedestrians. Therefore, the pedestrian detection trigger unit is generally deployed in areas where pedestrians are easy to come and go, and there is no light control and poor lighting environment. , the detection range of a single LeVideo integrated machine is 40-70 meters in the vertical direction and 30 meters in the horizontal direction. Therefore, for roads within the width of 70 meters, it is sufficient to deploy a set of pedestrian detection trigger un...

Abstract

The invention relates to the technical field of vehicle-road cooperation, in particular to a roadside system for prompting passing vehicles when pedestrians cross a street, which comprises the following components: C1, a pedestrian detection triggering unit: when pedestrians, non-motor vehicles and other targets pass through a detection area, a thunder-vision fusion all-in-one machine sends out an early warning signal, finally, the information is transmitted to the vehicle early warning prompt unit and the RSU through two information links. C2, a vehicle early warning prompt unit: after the vehicle early warning prompt unit receives the control information, the vehicle early warning prompt unit is linked with an LED high-brightness indication board to pop up preset early warning text information, and controls the lamp board to keep flickering or normally lighting in a certain period; C3, a RSU data communication unit: the data is sent to a cloud platform and a vehicle-mounted OBU when the RSU receives effective data, and the cloud platform and the vehicle-mounted OBU can receive and prompt the same early warning information as roadside facilities in real time; and after the pedestrian passes, the early warning signal disappears, the highlight lamp board and the LED high-brightness indication board are recovered to the initial state, and the RSU does not send early warning information any more.

Description

technical field [0001] The invention relates to the technical field of vehicle-road coordination, in particular to a roadside system for reminding passing vehicles when pedestrians cross the street. Background technique [0002] In the current urban roads, in order to facilitate pedestrians to cross the street, a large number of pedestrian crossings are set up near the gates of public places such as hospitals, governments, etc. Although relevant policies have been issued at present, motor vehicles must give way to pedestrians when passing a pedestrian crosswalk, but many times pedestrians are in the blind spot of the vehicle driver's vision, such as pedestrians are blocked by the surrounding environment when they are on the side of the road or between two-way lanes, and pedestrians have already left. Even if the driver consciously reduces the speed and faces the sudden appearance of pedestrians, there is no guarantee that he can react in time and avoid pedestrians when he is...
