路内停车对非机动车道通行能力的影响

为给非机动车道路内停车泊位的优化设置提供理论依据,运用交通冲突分析技术,研究了有机非隔离带的路内停车对非机动车通行的影响,构建了路内停车影响下的基本通行能力模型;在此基础上,考虑影响通行能力的因素非机动车道有效宽度、交通构成和时间障碍率,计算出相应的基本通行能力修正系数,得到路内停车影响下的实际通行能力模型.实例应用结果表明:路内停车使非机动车道实际通行能力降低了14.04%;通行能力计算结果与实际值的误差为4.56%;距离隔离带开口近的泊位比较远泊位对非机动车的影响小. 

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.
