Research of the lane utilization with microsimulation

The lane utilization ratio reflects the traffic distribution on different lanes of road section for a single direction. It influences the stability of traffic flow, and is the important influential factor of road capacity and security. Aiming at the uncertainty of the lane utilization ratio and the difficulty to collect the field data under different volumes, in this paper, the research is carried out with microscopic traffic simulation model of car-following and lane-changing to study the basic rules of the lane utilization ratio/lane-changing times and the lane utilization ratio/traffic volume of the road section with two carriageways or three carriageways.
