Macroscopic and Microscopic Analysis of Chinese Typical Driving Behavior from UAV View

For improving the performance of ADAS and AD system in China, driving behavior Chinese drivers is being increasingly focused. The purpose this study to investigate macroscopic microscopic characteristics typical behavior, by using UAV capture extract them. Traffic flow rate, traffic density, velocity, acceleration offset from lane center were acquired their influence vehicle types studied. Minimum TTC THW during changing car following also Results showed that state was more stable than Germany, however, with aggressive compared HighD. entire velocity small due strict speed regulation China. Different found for different types, lanes. Car car-car dangerous potential. Cars tended drive left trucks right center. Conclusions can be made largely German behavior. These driver China provided data support training an AI-based decision algorithm, development a localized design roads.
