Embodiment

[0018] Such as figure 1 As shown, the present invention provides a method for drawing schematic diagrams suitable for traffic information expression, and its specific steps are:

[0019] Step 1. Divide the traffic information into n display levels based on the road network to express the traffic information according to the size of the geographical range, wherein, n≥1, the first display level is the largest regional road network map that can be drawn;

[0020] Step 2. Set the size of the basic block corresponding to each display level except the first display level. Different display levels correspond to different sizes of basic blocks. Based on the basic blocks of each display level, the above-mentioned largest regional road network diagram Carry out block, and build index for each block, described block step is:

[0021] Step 2.1, determine the block reference point of the road network, and the coordinates of the reference point remain unchanged;

[0022] Step 2.2, acc...

Abstract

The invention provides a schematic diagram drawing method suitable for traffic information expression, which is characterized by comprising the steps of: firstly, dividing traffic information into n display levels based on road network expression traffic information according to the size of geographic range; secondly, blocking each display level, and establishing an index for each subblock, screening each road in each subblock of each level according to different demands, determining a road entity to be drawn, and drawing a traffic information background image after simplifying geographic attributes of each road entity; and thirdly, sending an inquiry position and an inquiry range by a user through a mobile phone, sending the traffic information background image of the position of the user to the user and displaying on the mobile phone of the user. The invention has the advantage that the traffic information can be rapidly displayed according to the current position and the inquiry range of the user on a mobile terminal by fully utilizing the traditional mobile resources.

Description

technical field [0001] The invention relates to a method for expressing traffic information, in particular to a method suitable for expressing traffic information in a mobile terminal by using schematic diagrams. Background technique [0002] Traffic information service is one of the core contents of intelligent transportation system. It is of great significance to improve urban traffic conditions and assist users to travel. Its potential social value and commercial value are gradually emerging. The success of traffic information service mainly depends on two factors, one is the content and reliability of traffic information, and the other is the way of expressing traffic information. The content and reliability of traffic information depend on the means of collecting traffic information and the accuracy of related models, and are invisible to users. However, the expression of traffic information is directly oriented to travel users and is the most important interface for us...
