Summary
This study addresses the need to evaluate the impact of intelligent vehicles on urban traffic flow, specifically within mixed-traffic environments containing varying levels of automation. As autonomous vehicle technology evolves, transportation decision-makers require accurate simulations to understand how non-assisted, driver-assisted, and fully autonomous vehicles interact. Previous research often limited simulations to highway segments or simple intersections and frequently ignored the intermediate transition phase of partial automation. This paper extends prior work by simulating three distinct automation levels—representing the present, near future, and distant future—within a complex, real-world urban network. The methodology employs microscopic traffic simulation focused on the inner ring of Duisburg, Germany, a medium-sized city with a dense transportation network. To ensure high scenario accuracy, the authors collaborated with local government agencies to obtain official data, including Origin/Destination (OD) matrices, induction loop data, and traffic light plans. Traffic demand was generated using both OD matrices and induction loop records, with the generated volumes validated against actual induction loop data. The simulation utilizes a driver–vehicle separate model, which allows for flexible combination of vehicle types and driver behaviors. The driver model simulates human reactions based on ego-vehicle and surrounding traffic conditions, controlling gas and brake pedals, while incorporating a modified Krauss car-following model to minimize conflicts with lane-changing logic. The study simulates vehicles with different degrees of automation within the Duisburg inner ring scenario, which includes major intersections, shopping districts, and public transport hubs. By integrating official OD and induction loop data, the researchers created a realistic representation of traffic demand, excluding public transportation to focus on passenger cars. The simulation compares the traffic flow effects of non-automated vehicles, those with driver assistance systems, and fully autonomous vehicles. This approach allows for the analysis of a long hybrid period where vehicles of various automation levels coexist, addressing a gap in previous studies that typically compared only non-automated and fully automated models. The significance of this work lies in its application to future urban mobility planning, particularly for car-sharing and autonomous taxi services in city centers. By providing a validated simulation framework for a highly meshed urban network, the study offers transportation planners a tool to assess the benefits and challenges of integrating intelligent vehicles into existing infrastructure. The findings support the understanding of how mixed automation levels affect traffic stability and throughput in complex urban environments, aiding in the development of policies and infrastructure adaptations for the gradual adoption of autonomous driving technologies.
