A system for traffic operation index calculation is applied to a computer. The system comprises: a traffic index function defining unit, which is based on a route-to-time ratio and defines a traffic operation index function by setting up a conversion relationship between the route-to-time ratio and a traffic operation index; a data collection unit, which calibrates an expected speed and an expected route time of vehicles of each road section and collects the route time and the driving speed of each road section and each road network; a route-to-time ratio calculating unit, which calculates the route-to-time ratio of a road network in a specific time period and the route-to-time ratio of a road section in the specific time period; a traffic operation index calculating unit, which calculates a road network traffic operation index and a road section traffic operation index in different spatial dimensions according to the route-to-time ratios of the road network and the road section; and a result outputting unit, which outputs the road network traffic operation index and the road section traffic operation index obtained through calculation above for reference of a user. The invention also provides a method for traffic operation index calculation.
