Abstract

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.
