Preferably, in described information processing module, the GPS of the elements of a fix of the GPS in current vehicle and congested link is determined
Position coordinate is compared, when in vehicle distances congested link coordinate range 1km, if information of voice prompt is within the ageing time
Do not meet the requirements, then the information is automatically deleted after aging time exceedes, force to play if vehicle is in this area and be somebody's turn to do
Information of voice prompt.
Preferably, the information of voice prompt can be configured in the ageing time.
When the vehicle pulls away, GPS starts to position current vehicle latitude and longitude coordinates, and RDS traffic dispersion broadcast systems start to receive
Traffic information, the scope of traffic information is centered on vehicle, in the range of radius is 30km.
With current GPRS accuracy computations when a crossing gets congestion, can navigate to be directed to four sides it is each
Crossing issues different vehicles and dredges information, and such effect is more effectively and more direct than traffic police floor manager；Certainly such message
It is ageing should be it is very short, thus be avoided that vehicle has crossed the prompt message at the next crossing behind crossing and played.
Prompt message that is ageing or updating the section repeatedly can also be extended if necessary；On common peak
During the phase, section coordinate range before the peak section can be entered in vehicle and launch warning information, can so carry vehicle
Preceding lane change gets around congested link, similar this section it is ageing can somewhat long point, can so avoid updating the road conditions repeatedly
Information；
If section is unimpeded in advance, the new traffic information of one promptness of issue can be updated immediately not in congestion
Road conditions before covering, when road of the terminal before the traffic information for receiving same area can be automatically deleted same coordinate region
Condition voice；
If similar road ahead is Under Repair or obstructed, addressing is launched and attended the meeting into the section crossing position,
When being issued in view of information, it may not start vehicle at that time, therefore vehicle can be not received by the traffic information in the section,
It can then cause before traffic information updates, vehicle is not having information alert into the section.
The cost that the program is realized is relatively low, and headend equipment hardware device change very little, mainly operates software and issue is flat
Platform system, the hardware of terminal is mainly comprising RDS radio modules, GPS module, signal memory module, master control system；Integrated modular
Chip, which can be embedded in original Vehicular multimedia all-in-one machine, realizes coordination control, and so conventional vehicle mounted guidance all-in-one just increases
Add RDS traffic dispersion systems, in order to not influence conventional broadcast, double frequency can be made, both conventional broadcast and RDS were handed over
It is logical to dredge broadcast.
Compared with prior art, the device have the advantages that being：
D GPS locating module of the present invention and RDS data broadcastings, which coordinate, can both complete required work, and cost is relatively low, does not appoint
What cost of use；The present invention can enable vehicle-mounted broadcasting receive accurate, timely, effective emergent broadcast, serve in advance
The effect of early warning；Platform this can be met an urgent need to realize when dredging of traffic with utility, non-congestion regions will not be caused
Vehicle also plays same emergency information.
