Provided is a mechanism for producing an uncertainty-based traffic congestion index, wherein the mechanism may comprise: obtaining a plurality of GPS data points; dividing the plurality of GPS data points into a plurality of variable sliding windows, wherein the dividing maximizes an amount of shape information in each of the plurality of variable sliding windows, performing a map matching process on the plurality of GPS data points as the GPS data points had been divided by the dividing; calculating a confidence value indicative of the map matching process; and producing the traffic congestion index, wherein the traffic congestion index is produced by taking into account the calculated confidence value indicative of the map matching process. In various embodiments, such a mechanism may be implemented via systems, methods and/or computer program products.
