摘　　要：采用实地调查和网络问卷调查的方式获取相关交通数据,以西安市历史街区为例,对历史街区自行车交通特性进行了研究.得到历史街区自行车的到达特征如骑行者年龄、到达时段、到达距离、到达时耗等特征;自行车的速度特性;建立了自行车流速度、密度和交通量三要素之间的函数关系并进行拟合验证;得出路段内机非摩擦干扰对自行车流的干扰特性以及交叉口右转机动车对过街自行车流和单辆自行车的干扰特性.通过对历史街区自行车流的定量与定性研究,其成果为街区及路网规划、改善设计、交通组织提供参考,对进一步构建历史街区慢行交通数据库提供数据基础.With the method of field observation survey and network survey methods to obtain relevant traffic and based on historical blocks of Xi'an City,the bicycles' transportation characteristics in the historical block was studied.Conclusion was come up with the bicycle arrival characteristics of historical block,such as the age bicycle rider,time and distance of arriva etc;the speed characteristics of bicycle.The function relation of bicycle's three elements--traffic flow rate,density,traffic volume was established.The friction interference between motor vehicle and non-motor vehicle in the historical block section,the interference between right-turn motor vehicle and bike with bicycle flow in the historical blocks,intersection were basically derived.Through the qualitative and quantitative study of bicycle traffic in the historical block,it provides important reference basis of historic blocks' network planning,and this helps improve the design and traffic organization.It also provides a data basis for constructing the database of slow traffic in the historical blocks.
