摘要

为给城市道路规划与设计提供参考依据，通过开展路侧自行车干扰条件下城市干路路段交通调查分析，给出了路侧自行车数量对其邻近机动车道平均行程车速、小客车饱和车头时距的影响规律，采用回归分析方法分别构建了相应的关系模型.基于所建理论模型，给出了城市干路路段实际通行能力计算的路侧自行车数量修正系数建议，并进行了实例验证；提出了路侧自行车干扰下的城市干路路段服务水平评价指标与分级建议，基于服务水平分析给出了设置机非分隔设施的路侧自行车数量阈值建议.研究表明：随着自行车数量的增加，平均行程车速降低，而饱和车头时距增加，均满足二次函数关系；路侧自行车数量越多、设计速度越高、实际通行能力的路侧自行行车数量修正系数越小，说明其对通行能力的影响越大；在服务水平相同的情况下，设计速度越高，对应的路侧自行车数量阈值越小，说明设计速度高的城市道路路段交通运行受路侧自行车干扰的影响更大.

Abstract

In order to provide reference for urban road planning and design

a traffic survey was conducted under the interruption of roadside bicycles. The influences of the number of roadside bicycles on average travel speed and cars' saturated headway of adjacent lane were analyzed

and the models between them were established respectively by regression method. Based on established models

suggested adjustment factors were given to calculate possible capacity of urban arterial road segment

and case study was conducted. Thresholds of the number of roadside bicycles were presented to evaluate LOS (level of service) and set separate facilities on urban arterial road segment. Results show that average travel speed decrease and cars' saturated headway increases with the increasing of the number of roadside bicycles

and the quadratic function relations between them is observed. The greater the number of roadside bicycle

the higher road design speed

the smaller the adjustment factor

indicating that the influence of roadside bicycle on road capacity is greater. The higher the design speed

and the lower the threshold of the number of roadside bicycles when LOS is the same

showing that the effects of roadside bicycle on traffic operation is greater for urban road segment with higher design speed.
