Can the Presence of Autonomous Vehicles Worsen the Equilibrium State of Traffic Networks?

摘要: It is known that autonomous vehicles are capable of maintaining shorter headways and distances when they form platoons vehicles. Thus, deployment can result in roadway flow capacity increases traffic networks. Consequently, it envisioned their will boost the overall network. In this paper, we consider a nonatomic routing game on network with inelastic (fixed) demands for set O/D pairs, study how replacing fraction regular (i.e. nonautonomous) by affect total delay, under assumption choose routes selfishly. Using well US bureau public roads (BPR) delay models, show resulting Wardrop equilibrium not necessarily unique even its weak sense networks mixed autonomy. We derive conditions which guaranteed to increase as increasing ratio However, also these do hold, counter intuitive behaviors might occur: grow particular, prove single pair, if road degree asymmetry between all autonomous) homogeneous, 1) unique, 2) nonincreasing continuous function autonomy fraction. heterogeneous degrees asymmetry, further increases. demonstrate similar may be observed multiple pairs.
