The invention discloses a path travel time reliability analysis method considering time headway characteristics, and the method comprises the steps: S01, obtaining the moments when vehicles on each lane in a target road section pass upstream and downstream detection points, and obtaining the vehicle passing moment data of each vehicle; s02, according to the vehicle passing time data of each vehicle, calculating the time headway of each vehicle passing the upstream and downstream detection points in the road section; s03, calculating a path travel time budget value by using a pre-constructed path travel time budget model according to the time headway of each vehicle passing through the upstream and downstream detection points in the road section, in the path travel time budgeting model, the mean value and variance of path travel time are respectively calculated by using the time headway of each vehicle passing upstream and downstream detection points in a road section; and step S04, obtaining a reliability condition of the path travel time according to the path travel time budget value. The method has the advantages of simple implementation method, small calculation amount, high analysis efficiency and precision and the like.
