1. The real-time traffic information display Introduction
real-time traffic, it is a concept for today’s urban road congestion traffic flow situation presented. Traffic is also referred to as real-time traffic information channel. Real-time traffic is already a mature intelligent transportation car navigation technology. Real-time traffic in real-time to reflect in the text area traffic road to guide the best and most efficient driving route, improve the efficiency of roads and vehicles.
car navigation one machine directly acquires traffic information via the receiving module built in or 3G network. Real-time traffic monitoring equipment can be installed on the road, or pointing device installed in the car, get real-time dynamic traffic situations they go through the sections.
advantage: real-time road information control, detour attempts to prevent
For car owners, it may not be the most troublesome fuel costs can only rise and not fall, it is not red tape maintenance, but is day live in congested roads of them, live a slower car than no car life. The master real-time traffic, you can give the initiative owners choose other roads.
some car owners will also get traffic updates through traffic radio, etc., in fact, this is also a way to get real-time traffic. But compared with TMC, on the lack of a macro information, it is easy to just escaped a congested road, fell into another one congested roads.
One drawback: where there is no delay message
In practice, the information displayed on the navigation system for transmitting orange, slow moving traffic. We can see and there are long queues of vehicles from the rearview mirror. Road and actually displayed on real-time traffic slightly different.
disadvantages two: the navigation route and the traffic information confusing
In general, in the navigation map, green represents clear, orange (or yellow) represent congestion, red for congestion, purple for navigation route. Colors and overlaps the navigation route at allThe user when in use is likely to cause visual error, the TMC real-time traffic information is displayed as a navigation route. And when an enlarged scale of the map when the map becomes smaller, this is more likely to occur.
