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

摘要

The present invention relates to a traffic volume estimation method and a traffic volume estimation device for estimating traffic volume by using average traffic time information at an intersection of a lake, Traffic estimation method using the average travel time information according to an embodiment of the present invention, An average travel time information receiving step of receiving average travel time information from an external server; An average delay time calculation step of calculating an average delay time using the average travel time information; A primary traffic estimation step of assuming that the traffic situation is a stable state with no dependency of time, and estimating primary traffic using the calculated average delay time; And applying a coordinate transformation technique for correcting the delay curve of a random delay to an actual delay curve, and estimating the secondary traffic volume in the near-saturated or supersaturated state using the calculated average delay time. .
