Mixed Manual/Semi-Automated Traffic: A Macroscopic Analysis

In this paper, the authors present a macroscopic analysis of mixed manual/semi-automated traffic. The analysis focuses on two topics: 1) the fundamental traffic flow-density diagram and, 2) traffic flow disturbances such as shock waves. The authors derive the fundamental traffic flow-density diagram for mixed manual/semi-automated traffic using the traffic flow-density diagrams for 100% manual and 100% semi-automated traffic. Using graphics and simulations, they show the effect of semi-automated vehicles on mixed traffic flow during the presence of disturbances such as shock waves. Finally, the authors demonstrate through queuing theory the effect of semi-automated vehicles on the average delay and number of vehicles in a queue on the highway during the presence of shock waves that produce stop-and-go traffic.
