采用虚线交通标线进行车辆定位及道路交通设施信息表征的方法

Method for Vehicle Positioning and Road Traffic Facility Information Characterization Using Dotted-traffic Markings

自动驾驶车辆行驶至隧道、高架桥下或高层建筑物林立的城区时,不能获取自身位置信息,导致自动驾驶和自动导航失效。为解决这一问题,设计一种特殊虚线交通标线,该标线由基本单元标线条单元和路面条单元组成,固定数量的基本单元按特定规则构成标线数据块,每个标线数据块对应一个二进制数进行信息编码,该码可表征数字、字母及特殊符号,信息编码后的标线就能表征车辆位置及道路交通设施信息,并设计配套识别程序,实现在特殊情况下对车辆所在位置的多种定位信息以及道路交通设施的多种管理信息进行现场数据查询、校核,为智能车辆运输、自动驾驶、无人驾驶、自动导航等系统提供特殊应急服务。

When an autonomous vehicle drives to a tunnel,under a viaduct,or an urban area with many high-rise buildings,it cannot obtain its own location information,resulting in the failure of automatic driving and automatic navigation.In order to solve this problem,a special dashed traffic marking is designed,which is composed of basic unit marking line unit and pavement strip unit.A fixed number of basic units constitute marking data blocks according to specific rules.Information coding is performed corresponding to a binary number for each marking data block,which can represent numbers,letters and special symbols.The marks by information code can represent the vehicle position and road traffic facility information,and a matching identification program is designed to realize the detection of vehicles under special circumstances.Various positioning information of the location and various management information of road traffic facilities are used for on-site data query and verification to provide special emergency services for intelligent vehicle transportation,automatic driving,unmanned driving,automatic navigation and other systems.
