Problems solved by technology

However, because the electronic map software used in the electronic navigation device is compiled and stored in advance, the content displayed by the VMS through the kanban cannot be learned and reflected by the electronic navigation device in real time, which increases the complexity of the information received by the driver. The driver also needs to comprehensively consider the information of the VMS and the information reflected by the electronic navigation device during the driving process of the vehicle; and it makes the driver switch back and forth between the short-range perspective and the long-distance perspective, which affects driving safety to a certain extent

Embodiment Construction

[0036] The map data used by electronic navigation devices is based on the road network on which the vehicle can travel. A road network is made up of road elements. A road element is a general term for a road segment (Link) and a road node (Node). A road segment refers to a road segment between two road nodes in the road network topology, and is an important element used to describe the road topology relationship. The interconnected road elements form the basis of the road network.

[0037] Traffic regulation refers to the traffic rules followed by driving. In fact, the more common ones are traffic signs and markings, such as turning left, going straight and other instruction information, or restricting information such as prohibiting traffic and prohibiting U-turn. These information are expressed as the relationship between road elements in the navigation map, that is, different traffic regulation information is reflected through road links and road nodes.

Abstract

The embodiment of the invention provides a variable message sign (VMS) application system, an electronic navigation method and a device thereof. The electronic navigation method comprises the following steps of: acquiring VMS information and an identification number of a VMS, wherein the VMS information comprises VMS dynamic information content and a VMS lane information classification code; according to the identification number of the VMS and the VMS information classification code, matching and searching a corresponding traffic regulation identification number; according to the traffic regulation identification number, matching and searching corresponding traffic regulation information; and carrying out navigation application according to the traffic regulation information. According to the embodiment of the invention, dynamic road information can be obtained by the electronic navigation device in real time, thus driving is guided by the electronic navigation device more effectively.

Description

technical field [0001] The invention relates to the navigation field, in particular to a variable information sign application system and an electronic navigation method and device. Background technique [0002] As part of the intelligent transportation system, Variable Message Sign (Variable Message Sign, VMS), sometimes abbreviated as CMS (Changeable Message Sign) or DMS (DynamicMessage Sign), records a variety of dynamic information related to roads and driving, such as Weather warning information, road special time period information, driving notice information, etc., mostly display dynamic information by hanging electronic display screens, usually installed on both sides or above the road, with fixed geographical location and signage orientation. [0003] VMS application system structure such as figure 1 As shown, the VMS monitoring center collects information provided by traffic police, as well as information provided by road administration, road construction and main...
