SYSTEM FOR REDUCING VEHICLE COLLISIONS BASED ON AN AUTOMATED AREA-SPECIFIC ASSESSMENT OF A COLLISION RISK
Systems and methods are disclosed for calculating a risk index for one or more areas (e.g., roads, intersections, bridges, and other transportation infrastructure). For instance, high risk intersections may be identified and mapped from historic auto insurance claim data. High risk intersections may be identified because of an excessive number of vehicle collisions there, and/or an amount and extent of vehicle damage, personal injuries, and/or insurance liability expenses associated with, or resulting from, the vehicle collisions at those locations. Risk indices for various areas may be compared to one another, enabling comparison of the relative riskiness of the areas. In some embodiments, a risk map may be generated to visually depict one or more risk indices for areas within a depicted region. The risk map may be used to quickly identify the riskiest area(s) in the region, and to notify government bodies to facilitate repairs and improve road safety.
