An apparatus for predicting a traffic hindrance risk having a traffic hindrance information generating server configured to generate traffic hindrance information encompassing congestion degree information including a current congestion degree obtained from a current value of driving data transmitted as probe data regarding a driving route from a vehicle equipped with a navigation system and a statistical congestion degree obtained from a statistical value of the current value of driving data in a certain previous period and a weather information generating server configured to generate weather information from weather data distributed by a meteorological agency with respect to an area including the driving route based on an weather model. In the apparatus, a traffic hindrance occurrence risk possibility of traffic hindrance occurrence with respect to the driving route is predicted from the congestion degree and weather information.

Traffic hindrance risk prediction apparatus

An apparatus for indicating a traffic hindrance risk, having a traffic hindrance information generating server that generates traffic hindrance information for links that define a driving route, and a weather information generating server that generates weather information from weather data distributed by a meteorological agency with respect to an area including the driving route. In the apparatus, a tabular data is generated together with congestion degree information by sorting foul weather information into a plurality of level categories in accordance with a degree of traffic hindrance when the weather information includes at least one item of foul weather information, and a traffic hindrance occurrence risk predictive value meaning possibility of traffic hindrance occurrence with respect to the driving route for a predetermined future period is calculated to be viewed by an operator of the vehicle.

Traffic hindrance risk indication apparatus

An apparatus for indicating a traffic hindrance risk having a traffic hindrance information generating server that generates traffic hindrance information for links that define a driving route on a mesh map. In the apparatus, the congestion degree information is colored in a color assigned in accordance with a numerical value defined to diminish with increasing congestion degree and is drawn the colored congestion degree information on the mesh map with respect to each of the links defining the driving route. And a traffic hindrance occurrence risk predictive value meaning possibility of traffic hindrance occurrence with respect to the driving route is calculated based on the drawn congestion degree information and is indicated to be viewed by an operator of the vehicle.
