非机动车廊道布局规划——以杭州市非机动车交通发展战略规划为例

Bicycle Corridors Planning and Design: a case study of strategic planning of Hangzhou bicycle network development

为使非机动车道网规划达到机非分流、便捷高效的目标,以杭州市为例,对廊道布局规划进行了探讨。在非机动车交通需求预测和流量分配的基础上,结合边界条件、用地性质和面积,进行非机动车慢行区划分;通过分析各类慢行区非机动车交通特征和组织策略,提出相应的廊道网络形态;进而根据非机动车出行高发区和换乘枢纽分布确定廊道布局的控制点,基于最短路径流量分配确定廊道布局的期望走廊,参照规划和现状道路条件确定廊道布局的具体路径,依据截面流量、规范推荐和公众意愿调查确定廊道布局的合理间距;最后在控制点、期望走廊、道路条件和廊道间距分析结果引导下,得到杭州市非机动车廊道布局方案,并验证了鼓励近距离出行的规划理念同时也符合交通需求预测分析的结果。

Taking Hangzhou as an example, this study explores non-motorized traffic corridor planning with an attempt to separate motorized and non-motorized traffic flows, thus to achieve convenience and effectiveness. First, a slow zone for non-motorized vehicles was delineated according to non-motorized travel demand and traffic assignment, and by considering marginal conditions, and land-use features, in particular, acreages. Through an analysis of traffic characteristics and operation strategies of non-motorized vehicles traveling within the slow zones, a corridor network was configured. The control points within the network were then determined by identifying areas with not only high travel demand of non-motorized vehicles but transfer terminals as well. Secondly, the expected corridors are determined by means of the shortest routes volume assignment. Then, detailed routes are obtained, according to present planning anf current roads information. Finally, based on traffic volumes, industrial recommendations and results from stated preference surveys, the reasonable buffer between corridors was given. Application of all the above aspects to the Hangzhou Non-motorized Corridor Planning Scenario shows that promotion of short travels is consistent with travel forecasting outcomes.
