Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
The embodiment of the present invention provides a kind of acquisition methods of graphical real-time traffic information, can make the graphical real-time traffic information at multiple crossings, terminal display front, better understands front road conditions and carries out rational decision-making for user.
The acquisition methods process flow diagram of a kind of graphical real-time traffic information that Fig. 2 provides for the embodiment of the present invention, comprises the following steps:
Step 201, user use terminal device (such as automatic navigator, mobile phone, PND etc.) that the position of vehicle current driving (longitude and latitude), direction, speed are uploaded to traffic information service platform.
Step 202, traffic information service platform are according to the section numbering of the longitude and latitude location positioning user place road of uploading.This section numbering is the section numbering that is pre-stored in the map in traffic information service platform.
Longitude and latitude position, direction, speed that step 203, traffic information service platform are uploaded according to user are determined travel direction, then according to travel direction and the definite section numbering of step 202, the graphical real-time traffic information at several crossings that in the certain limit of search front (or around), user may travel.In traffic information service platform, generate in real time all graphical real-time traffic informations in whole city.
Wherein, definite method of travel direction is: (determined voluntarily by traffic information service platform when continuous several moment of terminal device, for example can be decided to be 5 minutes, interval) passback position only have one, and speed is 0 o'clock, prove that this user is in dead ship condition, the interior all graphical real-time traffic informations of (border circular areas) certain limit around search; When the continuous several moment passback of terminal device position only has one, and speed is not 0 o'clock, proves that this user locates transport condition, searches for all graphical real-time traffic informations in the certain limit of front; When the continuous several moment passbacks of terminal device position is not 1, prove that this user is in driving process, the direction of now terminal passback is user's actual travel direction, according to the graphical real-time traffic information in this direction search front certain limit.
In definite method of travel direction, key is comprehensively to judge according to longitude and latitude location point, direction, the speed of user's passback, and judging with one of them separately can be inaccurate.For example: car was only passed a location point back in 5 minutes, but speed is 50KM/H, so now just can not take for vehicle in halted state, and reality is transport condition certainly, travel direction is that (for example vehicle is travelling user's upstream direction always, should return 10 location points, there is problem or equipment failure etc. in result network, only returned a location point); Car was only passed a location point back in 10 minutes, and speed is 0KM/, can judge so now stationary vehicle; Car returned 10 location points in 5 minutes, proved that this user is transport condition, and travel direction is user's upstream direction.
In addition, the decision method in front is: traffic information service platform is according to the topological relation of definite section, user place numbering, travel direction and the map that prestores of step 202, finds out the graphical real-time traffic information at each crossing of certain limit, front that user may travel.Described front certain limit can be determined voluntarily according to service condition, can be for example that the front fan-shaped angle of sector region 3KM(is to determine centered by the travel direction of car, for example in Fig. 3, fan-shaped angle is 60 degree, and the direction of arrow represents the travel direction of car, and angle is exactly 30 degree so on one side).Crossing number also can be determined voluntarily according to service condition, for example, can be 2 crossings.This is mainly to consider in the certain limit of front to have a lot of by qualified graphical real-time traffic information, if all displayed, and the one, hardware cannot all be shown; The 2nd, that shows is a lot, and it is better that user does not know which selects on the contrary.In addition in the process of travelling, supply the time of user's decision-making very short, generally know that the crossing road conditions of 2 left and right, front are just passable, if easily affect on the contrary too much user's decision-making.
For example: certain the A place that car travels in Fig. 4, travel direction is the direction of A to P, all has graphical real-time traffic information at O, M, N, L place.Learn according to the topological relation of the map of depositing in traffic information service platform, A does not allow while travelling to P, can not be from A-O-L, but can keep straight on and turn right, and can A-O-M-P, A-O-N, A-O-M-B.Owing to having graphical real-time traffic information at O, M, N, L place, and can not turn left, so only need and be issued to terminal by the graphical road conditions search at M, N, L place.
Step 204, traffic information service platform will search satisfactory graphical real-time traffic information and be handed down to subscriber terminal equipment.
The graphical real-time traffic information receiving is displayed the decision-making for user by step 205, terminal device.
The embodiment of the present invention provides a kind of application process of graphical real-time traffic information.In the process that can travel user by the method, show multiple crossings graphical real-time traffic information that may travel in front, avoid user to learn that at fast certain Lu Shicai of arrival this section blocks up, and now do not had other roads to choose, the section that can only select front to block up.If user is travelling and can learn the road conditions of front Multiple Intersections association now, can realize and preferentially choose more unimpeded section and travel, better evade the section that blocks up.
In a word, the foregoing is only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
