A CA Model for Intrusion Conflicts Simulation in Vehicles-Bicycles Laminar Traffic Flow

Bicycle traffic serves as an essential trip mode in many Asian countries, i.e. China. But along with the economic developments, the intense competition of drivers and bicyclists for right of way brings significant trouble to city traffic. This paper studies the driving and riding behaviors during intrusion conflicts in vehicles-bicycles laminar flow, which means that some bicyclists will intrude the lanes reserved for vehicles from time to time. A cellular automata model is proposed to model such conflicts and examine the variation process of traffic flow rate according to the density of vehicles and bicycles. A useful suggestion is made in this paper finally, which will be further applied in infrastructure planning.
