Critical Speed and Distance Analysis Based on Moving Vehicle Motion Model
Publication: International Conference on Transportation and Development 2020
ABSTRACT
With the development of intelligent connected network and cooperative vehicle- infrastructure systems, the research of dynamic safety distance is still playing an essential role in CVIS. A short distance between moving cars is dangerous for its incapacity of preventing various types of unexpected situations and potential hazards, meanwhile, a distance which is too long is inefficient in utilizing the traffic flow and road resources. Based on the physical model of automobile braking process and AASHTO (American Expressway and Transportation Association) model, this paper establishes the calculation model of critical safety distance in automobile driving process by analyzing the parameters of automobile braking acceleration, the time when the braking force reaches its maximum and driver’s reaction time. The simulation experiments prove that this model can effectively improve the traffic efficiency of highways and avoid traffic accidents, provided a theoretical reference for the automatic driving system, and the assisted driving system.
