Embodiment

[0027] In this embodiment, the case where a pedestrian crosses a zebra crossing due to bowing his head to play with a mobile phone or running a red light because his sight is obstructed is taken as an example, and the working process of the system of the present invention is described, and other situations can be deduced by analogy. Specific steps are as follows:

[0028] (1) Arrangement of zebra crossing warning light groups: the layout of zebra crossing warning light groups includes the arrangement of zebra crossing LED light group 1 (2) and zebra crossing LED light group 2 (5). Specification GB51038-2015 "regulations on pedestrian crossing lines, such as figure 1 As shown, taking the two-way four-lane vehicle lane width of 14.0m and the non-motor vehicle lane width of 7.0m as an example, the total road width is: 14.0m+7.0m=21.0m, and the number of zebra lines arranged: 21.0 / (0.45+ 0.6)=20 lines, (wherein, the width of the zebra crossing is 0.45m, and the spacing is 0.6m). ...

Abstract

The invention discloses a zebra crossing safety warning system suitable for a vehicle-road cooperation environment, and aims to solve the problem of insufficient traffic safety early warning capability of a street-crossing zebra crossing. The device comprises a monitoring system, a signal control system and a zebra crossing warning lamp group. According to the monitoring system, a multi-target radar detector is utilized, real-time synchronous transmission of data is achieved through an NTCIP communication protocol, and real-time recognition of traffic events is achieved; the signal control system comprises two groups of signal control units which are respectively used for controlling the phase and signal transmission of the zebra crossing LED lamp group; the zebra crossing warning lamp group comprises a zebra crossing LED lamp group and a treading power generation device located below the lamp set, so mechanical energy generated by pedestrians and vehicles on a zebra crossing can be converted into electric energy, and power is independently supplied to the zebra crossing LED lamp group. The invention can finally solve the problem of insufficient traffic safety early warning capability of the crossing zebra crossing, and has important practical significance and practical value for guiding a zebra crossing safety warning system taking establishment of a vehicle speed control andpedestrian warning system as a core.

Description

technical field [0001] The invention belongs to the field of traffic management and design engineering, and relates to a zebra crossing safety warning system suitable for a vehicle-road collaborative environment. Background technique [0002] The zebra crossing on urban roads is a node where various traffic flows meet, and the conflicts between vehicles and pedestrians, vehicles and non-motorized vehicles are very serious, resulting in particularly prominent traffic safety problems. According to the survey of traffic safety accidents on urban roads, accidents at this traffic flow node occur frequently, and the early warning capabilities of the traffic accident warning and safety warning system are insufficient, which cannot satisfy the smooth and safe operation of the traffic system at intersections, and are limited to a certain extent. The green traffic development of the whole city, in order to better deal with the frequent traffic accidents of crossing zebra crossings, ma...
