Problems solved by technology

If the traffic data at time T is still used when exploring the optimal route through point B, the situation that may result is: the route planned at point A shows that point B is unblocked, but when the car travels to point B, it finds that : The road conditions at point B are congested, resulting in inaccurate route exploration, which brings a lot of inconvenience to drivers

Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] figure 1 A block diagram of an apparatus for predicting traffic conditions according to an embodiment of the present invention is illustrated.

[0029] Such as figure 1 As shown, the traffic condition prediction device 100 includes a historical traffic data acquisition unit 101 , a classification unit 103 , a statistics unit 105 and a determination unit 107 .

[0030] The historical traffic data obtaining unit 101 obtains historical traffic data of geographic locations within each time period from a service provider. For example, the navigation device of the self-vehicle can obtain the historical traffic data of location A in a long period of time in the past from a service provider (such as a server of the traffic management department), and the long period of time is, for example, one month or several months , one year or several y...

Abstract

The invention provides a device for pathway exploration by utilizing predicted traffic data, which comprises a Link path forming unit, a segmenting unit, a weight calculation unit and a selection unit, wherein the Link path forming unit is used for forming all Link paths from an own vehicle to the destination, and the segmenting unit is used for segmenting the geographic region into a plurality of different regions which take the own vehicle as the center; the weight calculation unit is used for aiming at each Link path to calculate the weight of the Link path, and the selection unit is used for selecting the Link path with a minimum weight to be used as an optimal path; when the weight of the Link patch is calculated, the weight calculation unit uses real-time traffic data in a first region nearest to the own vehicle, and uses the predicted traffic data at the corresponding time in other regions.

Description

technical field [0001] The present invention relates to the technical field of navigation, and more specifically, to a device for predicting traffic conditions and a device for exploring routes by using predicted traffic data. Background technique [0002] With the continuous development of public transportation facilities, drivers increasingly need navigation equipment to explore routes, plan optimal routes, and guide their own vehicles to drive according to the planned routes. In the existing navigation equipment, the real-time traffic data when the self-vehicle departs is usually obtained from the service provider, and then the real-time traffic data obtained at this moment is used for route planning or route guidance, and displayed on the navigation map, so as to realize Explore by way. [0003] However, this "real-time" traffic data is too "real-time". For longer routes, if such real-time traffic data is used to explore, the practicability of the route is very poor. ...
