Form with little frame contrasts the recommendation road that is presented at the recommendation road after considering transport information and does not consider transport information on the navigation interface that display device 3 shows simultaneously, thereby the prompting user is in the superiority of the recommendation paths of considering to calculate after the transport information.
The factor that described total current cost is calculated comprises: the current cost sum of the current cost of road and incident; The related factor of current cost of described road comprises: category of roads attribute, road width attribute, road section length attribute, speed limiting attribute and paying attribute (referring to whether exist factors such as charge station); The related factor of current cost of described incident comprises: road closed, accident are blocked and jogging.For example, on a certain road, exist some to be in track in the construction, thereby cause this highway section to be in the jogging state.Can estimate by the required time of this jogging highway section according to factors such as the category of roads in the track quantity of the construction state that is in the unit distance or density, length and this highway section, total number of track-lines, width.
When in map image, describing Real-time Traffic Information,, then adopt corresponding road closed symbol and accident to block symbol and be presented on the corresponding highway section for the highway section that road closed, accident are blocked.
There is map datum in the memory device of vehicle navigator, these data presentation form map image on display screen, above-mentioned map datum also comprises some point of interest address informations, it usually is the major address of internal ratio, the higher or certain region of relevant frequency of utilization, these point of interest address informations are called point of interest, they can be identified out on map image, and can be by the user in the enterprising row-column list of omniselector, inquiry, when the user need can carry out setting operation when wherein certain point of interest address is as navigation destination easily.
See Fig. 3,, be set at different value, thereby when path computing, avoid the highway section that traffic events takes place for those fully by the difference of transport information to the influence of road driving.
Concrete implementation procedure is:
At first judge and whether load TMC Link data message the Real-time Traffic Information of TMC receiver 2 (promptly from);
Analyze the current cost of road then, wherein the current cost of normal road mainly calculates by attributes such as category of roads, road width, speed limits; The current cost of incident road is determined by the medium different factors of road closed and road construction.The current cost (Const) of road closed (Ramp Closed) is infinitely great.A passage is blocked up comprises that accident is blocked and jogging.Wherein the Const of accident obstruction mainly is a calculating treatmenting time, and the Const of jogging mainly is the estimation traffic capacity.Two kinds of infeasible and jogging are arranged, the infeasible road closed that promptly can be regarded as in the road construction.
Utilize dijkstra's algorithm to calculate from the car end optimal path to the destination end, more whether there are two different recommendation paths, if existing and just need comparing that paths is optimal path, method relatively mainly is to wait comprehensively by mileage, time and expense to compare.Wherein mileage be meant from from the car end to the destination end shortest path that travels, time be from from the car end to the required shortest time of destination end, expense comprises two aspects: charge expense and oil consumption expense, the charge expense comprises the extra cost that the road has more through charge station and expressway mileage increase etc., and the oil consumption expense is by road passage capability and mileage decision.
See Fig. 4, can find according to the daily life rule, peak period on and off duty at ordinary times, road is in not too unimpeded state basically, is especially running into rainy day, and traffic is not smooth especially.Under the situation that can not find a clog-free road, people have only wait.Yet people can select reasonably to go to arrange the stand-by period of this section.For example, can when running into obstruction, remove supermarket shopping, rather than on road, wait for.
See Fig. 5, the path computing that adds TMC obtains new recommendation paths, just needs to determine that new path of recommending is more excellent than original recommendation paths, and will point out the user to use new recommendation paths.At first judge and whether have new recommendation paths.Secondly in order to make the user obtain the information that traffic jam is taken a devious route more intuitively, the twice different recommendation paths in front and back can be drawn different colors, and, need detour, thereby realization is to the intelligent navigation of vehicle with voice and captions prompting user road ahead obstruction.
