技术领域technical field
本发明涉及智能交通信息服务领域,尤其涉及一种动态交通信息路段显示方法及导航显示器。The invention relates to the field of intelligent traffic information services, in particular to a dynamic traffic information section display method and a navigation display.
背景技术Background technique
目前,国际上已经形成了比较成熟的支持动态交通信息的路段编码国际标准和地区标准。欧盟的TMC(Traffic Message Channel,交通信息频道)标准,使用位置表/配表(Location Table/Matching Table)编码实现对交通信息的支持;日本的VICS(Vehicle Information and Communication System,道路交通情报通信系统)标准,其VICS Link ID编码实现了对动态交通信息的支持。At present, relatively mature international standards and regional standards for link coding that support dynamic traffic information have been formed in the world. The European Union's TMC (Traffic Message Channel, traffic information channel) standard uses location table/matching table (Location Table/Matching Table) codes to support traffic information; Japan's VICS (Vehicle Information and Communication System, road traffic information communication system ) standard, its VICS Link ID code realizes the support for dynamic traffic information.
我国发布了推荐国标《道路交通信息服务道路编码规则》,目前基于该国标的位置参考编码体系RTIC LR(Realtime Traffic Information of China Location Reference,中国实时交通信息位置值参考)已经在全国大中城市提供实时交通信息服务。RTIC LR编码体系支持FM-RTIC实时交通信息服务。my country has released the recommended national standard "Road Coding Rules for Road Traffic Information Services". Currently, the location reference coding system RTIC LR (Realtime Traffic Information of China Location Reference) based on the national standard has been provided in large and medium-sized cities across the country. Real-time traffic information service. RTIC LR coding system supports FM-RTIC real-time traffic information service.
RTIC LR以二次图幅为编码单位,每个图幅中的道路分为4个等级,每个等级的最大编码量是4095。受FM带宽限制,RTIC LR编码体系的等级和编码量都是有限的。因此只能对城市主要道路进行编码,用于发布或接收实时交通信息。RTIC LR takes the secondary frame as the coding unit, and the roads in each frame are divided into 4 levels, and the maximum coding amount of each level is 4095. Limited by the FM bandwidth, the level and the amount of coding of the RTIC LR coding system are limited. Therefore, only the main roads in the city can be coded for publishing or receiving real-time traffic information.
如表1所示,现有RTIC LR编码体系主要有四个等级。As shown in Table 1, the existing RTIC LR coding system mainly has four levels.
表1、现有RTIC LR编码体系Table 1. Existing RTIC LR coding system
