摘要
行人作为道路交通中的弱势群体:一方面在交通事故中最容易受到伤害;另一方面过街优先权经常得不到保证。斑马线是车辆与行人的主要冲突点,机动车的不礼让致使斑马线上的交通事故率越来越高。通过分析传统的过街设施服务特性及存在问题,采用智能化手段提高行人过街安全性和过街效率。智慧人行横道运用摄像头、雷达、微波、红外等检测技术,NB-IoT、4G等数据传输技术实现行人感应、数据采集、数据传输、数据挖掘等功能。重点介绍智慧人行横道的构成、功能、设置方式,并对试点的应用情况及存在问题进行探讨和分析。
Pedestrians as vulnerable groups in road traffic:on the one hand,they are most vulnerable to traffic accidents;on the other hand,the priority of crossing the street is often not guaranteed.Zebra crossing is the main point of conflict between vehicles and pedestrians.Incorruption of motor vehicles leads to a higher and higher rate of traffic accidents on zebra crossing.By analyzing the service characteristics and existing problems of traditional street crossing facilities,intelligent means are adopted to improve the safety and efficiency of pedestrian crossing.Intelligent pedestrian crosswalk uses camera,radar,microwave,infrared detection technology,NB-IoT,4G and other data transmission technology to realize human induction,data acquisition,data transmission,data mining and other functions.This paper mainly introduces the structure,function and setting mode of the intelligent pedestrian crosswalk,and probes into and analyses the application and existing problems of the pilot project.
