Abstract

The invention discloses a reaction device for reminding vehicles behind a bus during avoiding pedestrians and an application method thereof. The device comprises a pedestrian-vehicle state sensing module, an accident risk evaluating module and a light reminding module; the pedestrian-vehicle state sensing module is composed of a pedestrian state sensing sub-module and a vehicle state sensing sub-module, the pedestrian state sensing sub-module and the vehicle state sensing sub-module are used for sensing the state information of pedestrians in front of a bus and the state information of vehicles behind the bus respectively, the sub-modules are connected with bus vehicle speed sensors, and the accident risk evaluating module is used for calculating the possibility of pedestrian-vehicle conflict based on the sensed state information of pedestrians and vehicles. According to the device and the method, the accident risk can be transmitted to drivers of vehicles behind the bus when the bus avoids pedestrians crossing a street, so that the drivers of the vehicles behind the can obtain the potential safety danger existing in front in time, the occurrence rate of traffic accidents can be effectively reduced, and the device has great application value.

Description

technical field

[0001] The invention belongs to the field of traffic information prompts for urban traffic, and in particular relates to a reaction device for prompting vehicles coming from behind when a bus avoids pedestrians crossing the street and an application method thereof. Background technique

[0002] Conventional public transport is an important part of the public transport system, and it has received more and more attention today when vigorously developing public transport is encouraged. Due to the design requirements of the body size, the bus will inevitably affect the sight of other traffic participants when participating in traffic activities. Especially when the bus avoids pedestrians crossing the street, it is easy to block the sight of the drivers coming from behind, affecting their observation of pedestrians, thus posing a potential threat to pedestrians. The occurrence of many traffic accidents is because the driver's sight is blocked by the bus, which ha...

Embodiment Construction

[0027] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0028] In this embodiment, the reaction device of the present invention is applied to a bus, and the reaction device includes a pedestrian-coming vehicle state perception module, an accident risk assessment module and a light prompt module, and the pedestrian-coming vehicle state perception module consists of pedestrian state perception modules The module and the incoming vehicle state perception sub-module are composed of and respectively connected to the bus speed sensor. In this embodiment, the pedestrian state perception sub-module is composed of two 24GHz millimeter-wave radars, and the incoming vehicle state perception sub-module is composed of two 77GHz millimeter-wave radars. .

[0029] Such as image 3 As shown, two 24GHz millimeter-wave radars are respectively placed on the outer edges of the front of the bus at a height of 1.3m. The...
