Simulation Study on the Coupling Relationship between Traffic Network Model and Traffic Mobility under the Background of Autonomous Driving

Autonomous driving technology will bring revolutionary changes to the development of future cities and transportation. In order study impact autonomous on urban transportation networks, this paper first summarizes status technology, then three space–traffic network coupling models are proposed based differences speed space, which traditional difference type, scale variation slow-guided type. On basis, a new 4 * km grid city model is constructed. Based MATSim multi-agent simulation method, traffic parameters studied. The results show that under same demand, service level networks significantly different. optimal differential type 2.15 times efficiency Under demand road mode, travel mode 1.7–2.8 mode. lane area ratio, much smaller than driving, about 2.6–3.6 greater former. research conclusion has certain reference significance for formulating spatial strategies policies environments promoting sustainable
