Embodiment
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
As shown in Figure 1, be the application scenarios schematic diagram of an embodiment of real-time traffic information notification system of the present invention.In the application scenarios of the present embodiment, comprise three parts, be respectively: car-mounted terminal 1, real-time traffic information notification system 2 and external information platform (being Traffic Information platform 3 in the present embodiment).Car-mounted terminal 1 links to each other with real-time traffic information notification system 2 by mobile communications network, and real-time traffic information notification system 2 links to each other with Traffic Information platform 3.
The present invention is provided with real-time traffic information notification system 2 this background systems, can obtain vehicle location with the reservation cycle, and vehicle location and real-time traffic are mated, in time understand jam situation, and congestion information sent to car-mounted terminal, know to make things convenient for the driver.
Real-time traffic information notification system 2 specifically comprises three sub-systems, is respectively: transport information processing subsystem 4, user profile tracing subsystem 5 and transport information notice subsystem 6.Wherein, transport information processing subsystem 4 is responsible for obtaining the Real-time Road transport information with predetermined period from the external information platform, carries out Real-time Road transport information coupling with electronic chart, and the early warning virtual boundary in the more newly-installed highway section that blocks up.User profile tracing subsystem 5 is responsible for obtaining with predetermined period the geography information of car-mounted terminal, and mate with described electronic chart, and judge according to the geography information of described car-mounted terminal whether described car-mounted terminal is in the early warning virtual boundary in the described highway section that blocks up, if be in, then calculate the one or more unobstructed road path that gets around the described highway section that blocks up.Transport information notice subsystem 6 is responsible for by text mode current real-time congestion information being sent to described car-mounted terminal.
The concrete structure of transport information processing subsystem 4 can with reference to figure 2, be the structural representation of transport information processing subsystem among the real-time traffic information notification system embodiment of the present invention.In the present embodiment, transport information processing subsystem 4 comprises: transport information acquisition module 41, the first map-matching module 42 and virtual boundary arrange module 43.
Transport information acquisition module 41 is responsible for obtaining the Real-time Road transport information with predetermined period (such as 2,5 or 10 minutes etc.) from external information platform (for example the Traffic Information platform 3).The Real-time Road transport information here comprises road section information, average speed, car flow information etc., but the information type that is not limited to give an example here.
The first map-matching module 42 responsible electronic charts that will obtain ground Real-time Road transport information and this locality carry out Real-time Road transport information coupling.Mate by the highway section in road section information and the electronic chart, can judge whether be in congestion status by average speed and the car flow information in this highway section again, on electronic chart, can identify with different colours the average speed of different range, and then express the traffic in this highway section, for example for the highway section of average speed＜20km/h, then this highway section is with red display or covering, and expression is in congestion status; For the highway section of average speed at 20～40km/h, then this highway section shows with yellow or covers, and expression is in general state; For the highway section of average speed＞40km/h, then this highway section shows with green or covers, and expression is in unimpeded state.Specifically how to identify the highway section congestion, can adjust according to actual conditions, here only as the convenient explanation of example.
Virtual boundary arranges the early warning virtual boundary that module 43 is responsible for according to the more newly-installed highway section that blocks up of described Real-time Road transport information.This module can further specifically comprise: the highway section search unit that blocks up, peripheral information acquiring unit, virtual boundary computing unit and dynamically arrange the unit.The highway section search unit that blocks up is responsible for searching for the highway section that meets congestion status in described electronic chart.The front has been mentioned and can have been determined whether the highway section meets congestion status according to factors such as average speed, wagon flow situations.The peripheral information acquiring unit is responsible for obtaining the Traffic Information of the peripheral path relevant with the described highway section that meets congestion status, the Traffic Information of the peripheral path here can be and the Traffic Information of highway section at a distance of limited highway section that block up to comprise average speed, road section length and/or the intersection information etc. in these highway sections.The virtual boundary computing unit is responsible for arriving the time in the highway section that blocks up according to the road average speed of peripheral path and length computation, and calculates the early warning virtual boundary in the highway section that blocks up in conjunction with the intersection information that arrives the highway section that blocks up.
For instance: search for the highway section that blocks up, then highway section crossing highway section is according to the map therewith blocked up, be made as the first highway section, and the like to the Third Road section (if there is coincidence then to be made as previous highway section, both be the first highway section such as a highway section, be again the second highway section, then be made as the first highway section), and begin the place in the Third Road section reference point is set; Then respectively according to average speed and the length in highway section, calculate each reference point to the shortest running time in the highway section that blocks up, if the shortest running time less than 5 minutes, the 4th highway section take this highway section as benchmark then, by that analogy, until the shortest running time was greater than 5 minutes.After obtaining final reference point, take the final reference point as basis instrument early warning virtual boundary.
Calculate the early warning virtual boundary in the highway section that blocks up at the virtual boundary computing unit after, dynamically arrange the unit and be responsible for upgrading setting according to the early warning virtual boundary in this highway section that blocks up.
