Impact of Curbside Parking on Bicycle Lane Capacity

In order to provide a theoretical basis for optimization and setting of the curbside parking on bicycle lanes, the traffic conflict technique was used to analyze the effect of curbside parking on the bicycle flow in segregated bicycle lane and establish a basic capacity model under the influence of curbside parking. On this basis, adjustment factors of the basic capacity were calculated by considering the influential factors of the capacity including the effective width, the traffic composition, and the time influence rate. Then an actual bicycle capacity model under influence of curbside parking was established. Application results show that the bicycle lane capacity is decreased by approximately 14.04% under the influence of curbside parking. The absolute error between the observed capacity and the estimated capacity is only 4.56%. The berths near the openings of isolation belt have less influence than in the middle position.
