How Will the Presence of Autonomous Vehicles Affect the Equilibrium State of Traffic Networks

摘要: It is known that connected and autonomous vehicles are capable of maintaining shorter headway distances when they form platoons vehicles. Thus, such technologies can potentially increase the road capacities traffic networks. Consequently, it envisioned their deployment will also overall network mobility. In this paper, we examine validity expected impact, assuming drivers select routes selfishly, in networks with mixed vehicle autonomy, is, both regular We consider a nonatomic routing game on inelastic (fixed) demands for set origin destination (O/D) pairs, study how replacing fraction by affect mobility network. Using well-known U.S. Bureau Public Roads delay models, show resulting Wardrop equilibrium not necessarily unique autonomy. Then, state conditions under which total at guaranteed to as increases. However, these do hold, counterintuitive behaviors may occur—the grow cars particular, prove single O/D pair, if degrees capacity asymmetry (i.e., ratio between all autonomous) homogeneous, is: 1) 2) nonincreasing continuous function heterogeneous asymmetry, unique, further demonstrate similar be observed multiple pairs. bound performance degradations due introduction autonomy general homogeneous
