Abstract

Allowing level 4 Automated Vehicles to drive on highways could significantly impact the traffic efficiency and safety. Although it might probably take a while before AVs are on the road, NRAs (National Road Authorities) are already investigating how to adapt their current infrastructure to make it ready for AVs – while optimizing both traffic efficiency and safety. Therefore, in this paper we simulate a highway section in VISSIM including a weaving section calibrated with empirical data. We test different taper lane lengths, different demand levels (0.55 and 0.80 F/C ratios) and different CAV penetration rates (0-100%) and we assess the impact on traffic efficiency and safety. It is concluded that increasing AV penetration rates lead to decreasing travel times for all road users (automated and non-automated). Different taper lane lengths as well as different traffic flow levels do not seem to influence the observed pattern much.
