Claim:
1. A method of providing an analysis index using a processor, computer executable instructions for performing the method being stored on a non-transitory computer readable recording medium and being implemented by the processor when executed, the method comprising: collecting information regarding the number of traffic lights installed in a roadway section and information about at least one of a curvature and a gradient of the roadway section with a GPS module, a sensor, or a camera while a vehicle is moving on the roadway section; calculating, by the processor, the traffic light density of the roadway section on which the vehicle is moving using the number of traffic lights installed in the roadway section and GPS information of the vehicle; calculating, by the processor, the road shape information based on at least one of the curvature and the gradient of the roadway section using the GPS information of the vehicle; calculating, by the processor, a speed variation of the roadway section using a change of speed in the roadway section; calculating, by the processor, an analysis index of the roadway section based on the traffic light density, the road shape information, and the speed variation; providing, by the processor, the analysis index in displayable form; and using the analysis index to determine a route of the vehicle with a recording device or a navigation device, thereby improving the route determination capability of said device; wherein calculating the analysis index of the roadway section comprises calculating the analysis index by subtracting at least one of the traffic light density, the road shape information, and the speed variation from a reference value.
