Estimation of Travel Time Reduction Benefit Considering the Travel Time Reliability in an Autonomous Vehicle Prevailed Road Network

Abstract

Development of automatic driving technology is proceeding. In this paper, a traffic flow assignment method for estimating the travel time reduction benefit brought by the spread of autonomous vehicles is proposed. For the two networks, i.e., the network where human driven vehicles are prevailed and the network where autonomous vehicles are prevailed, two generalized total travel times are estimated by the proposed method. From two generalized total travel times, the benefit thanks to autonomous vehicles is then calculated. In addition, sensitivity analysis is also carried out to see how the traffic flows are influenced by exogenously given calibration parameters.
