  "textContent": "An approach is provided for computation of risk index. The approach, for example, involves acquiring historical probe data associated with an area. The historical probe data comprises data associated with distribution of vehicles entering or leaving the area in a given time partition. The approach further involves obtaining map feature data associated with an entrance or exit of the area, from a geographical database. The map feature data comprises data associated with physical objects in vicinity of the area. The approach further involves computing a risk index for the entrance or the exit for the given time partition, based on the historical probe data and the map feature data. The risk index indicates a probability of occurrence of a hazard in the vicinity of the entrance or the exit. The approach further involves storing the risk index as an attribute of the entrance or the exit in the geographic database.",
