摘  要

我国车道宽度值选取主要依据波良科夫模型计算得到,且模型计算选用参数参照 20 多年前道路及汽车科技水平。现今道路行驶条件及汽车研发科技均得到不同程度改善与提高,故应根据实际情况修正模型涉及各参数,以得到合理车道宽度取值。

国外对于车道宽度研究主要针对公路展开,其道路横断面组成、车种构成及车辆运行环境与国内存在较大差别;国内关于车道宽度合理取值研究大都以城市快速路、主干路及次干路为研究对象,对支路尤其是交通性支路车道宽度合理取值研究甚少,且有关高等级道路研究均以某一城市为背景。

论文以高密度路网为研究背景, 从路网密度及道路间距两方面阐述高密度路网物理特征,并选取行程车速和交通流量两大参数描述高密度路网交通特征,从而诠释高密度路网所具备的特点。

本论文以双向两车道交通性支路为研究对象,将上海市内环内浦西地区支路出租车FCD数据及公交车 GPS 数据作为 85%位车速分析数据来源,结合国顺路及政修路视频数据,借助视频交通事件检测器及 SPSS 软件,利用数理统计方法分析得到不同时段及车种 85%位车速值、车辆横向偏移分布特征、混行车种比例等数据,以全时段 85%位车数值和上海市常用车型车身宽度修正波良科夫模型中速度及车身宽度参数值,计算得到相应车道宽度,并以实测双休日高峰期横向偏移值为偏移控制值校核计算偏移值,综合考虑混行车辆比例、支路交通量及已有车道宽度建议值研究等方面提出高密度路网条件下双向两车道交通性支路车道宽度建议值。

ABSTRACT

Still, in our country, lane width is mainly decided by Bolankerf model, which parameters are not suitable for the road environment and vehicle technology now, cause the whole level is different from the one that 20 years ago. With the development of road condition and vehicle technology, it is necessary to modify parameters according to practical situation in order to get much more reasonable lane-width.

Oversea prevenient research is mainly about highway which the road cross-section components, vehicle types and drive environment are widely different from domestic ones. Even domestic research is just about high grade urban road, including expressway, primary arterial and secondary arterial, what’s more, the existent achievements are suited for just one city. And there is scarcely any research about lane-width of collector, especially about collectors that play important part in traffic system.

This paper is studied on the base of high density urban road network. There are two parts considered to explain the characteristics of high density urban road network, including road characteristics and traffic haracteristics. Moreover, characteristics of the former one are described by terms of road density and road space and when talked about the latter one, characteristics of travel speed and traffic volume are considered.

And also, the study aims on two-lane road which is important for traffic system. Paper selects FCD of taxis and GPS data of buses in inner ring of Puxi Shanghai as raw data which can be used to analyze 85th percentile speed. At the same time, with the help of traffic incident detector and SPSS, this paper analyzes video data of Guoshun road and Zhengxiu road to get the features of distance of lateral deviation, 85th percentile speed of different period and vehicle types as well as proportion of different vehicle type and during this process, method of mathematical statistical is used. In the paper, the 85th percentile speed of 24-hour data of each vehicle type and the width of main vehicle type are selected to modify Bolankerf model and then calculate the lane-width which is checked by the lateral deviation distance of peak hour of weekend. And then it gives consideration to all factors including proportion of different vehicle type, volume and existent lane-width research and then gives reasonable lane-width for collector which in the road network of high density.

Key Words:  Lane-width of collector, high-density road network, Bolankerf model, 85th percentile speed
