Traffic estimation method using average travel time information and traffic estimation device

摘要

The present invention relates to a method for estimating traffic volume and an apparatus thereof, which estimate traffic volume using average travel time information at a signal intersection. According to an embodiment of the present invention, the method comprises: an average travel time information receiving step of receiving average travel time information from an external server; an average latency time calculating step of calculating an average latency time using the average travel time information; a first traffic volume estimating step of assuming a traffic condition as a stable state without time dependency and estimating a first traffic volume using the calculated average latency time; and a second traffic volume estimating step of applying a coordinate conversion technique for correcting a latency curve of a random latency model to an actual latency curve and estimating second traffic volume in a near-saturated or supersaturated state using the calculated average latency time.
