Traffic hindrance risk indication apparatus

An apparatus for indicating a traffic hindrance risk, comprising:

• a traffic hindrance information generating server configured to generate traffic hindrance information for links that define a driving route on a mesh map,
• the 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 the 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, the congestion degree information being sorted into a plurality of level categories in accordance with a driving speed in the driving data;
• and
• at least one processor and a memory coupled to the processor;
• wherein the processor and the memory are configured to perform:
• coloring the congestion degree information in a color assigned in accordance with a numerical value defined to diminish with increasing congestion degree and drawing the colored congestion degree information on the mesh map with respect to each of the links defining the driving route;
• and
• calculating a traffic hindrance occurrence risk predictive value meaning possibility of traffic hindrance occurrence with respect to the driving route based on the drawn congestion degree information and indicating the traffic hindrance occurrence risk predictive value to be viewed by an operator of the vehicle.
