After state, need for the state of vector road and the vector road to generate corresponding road conditions picture, then road conditions picture is sent to
Client.And the present invention need not carry out the generation of road conditions picture in server end, only need to be by road id and the state of road
(status) send, save the process time of server end, save the stream that server end sends road conditions picture to client
Amount.
In step S130 and step S140, in order to show road conditions, client needs the face of each state for arranging road
Color display mode.For example,<Heavy congestion, brown shows>,<It is crowded, red display>,<Smooth, green shows>, seriously gather around
Stifled, crowded and smooth each state for road, brown shows, red display and green are shown as the color of each state and show
Mode.
The configuration information of whole roads is previously stored with the target area in client, be that is to say previously positioned every

It is the road of which kind, and it is the data for finally needing to render to change sampled data, i.e., corresponding color shows, so as to realize
The display of road conditions.For example, the rendering parameter of road A is<The color value of pink colour, brown shows>, sample pink colour in the map
Color value when, you can the native color value to determine the color value of the pink colour as road A, then according to the rendering parameter by the road
Road A is rendered into brown, and user can determine that road A is heavy congestion according to the brown that road A shows.Can adopt
GLSL (OpenGL Shading Language, shading language) method carries out the sampling of map, sweeps without carrying out individual element
Retouch, pixel acquisition speed is faster.
Client needs to show two figure layers of base map and road in conventional art, needs to consume more resources.And this
Bright need render a figure layer, you can the road conditions as road figure layer are superimposed on the base map in complete conventional method and show effect
Really.Due to render figure layer is few, therefore reduce CPU (Central Processing Unit, central processing unit) and video memory etc.
