城市中心区非机动车系统设计优化与探索

随着社会经济的发展与城市规模的扩张，城市交通需求大幅度增加，自行车和电力驱动非机动车数量急剧增加，与传统非机动车以及机动车的运行冲突显著。因此，探究非机动车系统运行特性，进而设计优化道路设施，建立新形势下安全、高效的绿色非机动车系统十分必要。首先，针对非机动车系统中的主要参与模式，即电动车与自行车之间的冲突以及共用非机动车道空间的局限性，提出了车道分隔设置以及车道平面抬升的核心改善思路；然后，针对非机动车道改善方案定量分析方法的缺失，提出了基于层次分析法和熵理论的定量指标评价体系及计算方法；最后，以焦作市非机动车系统为案例，分析其现状及主要问题，设计并评价改善方案的可行性和合理性。结果显示，某主干路非机动车道经过优化设计，其运行服务质量大幅提升，改善方案行之有效。对城市道路规划和城市道路断面设计以及改善后非机动车道的评价有积极的参考意义。 

Optimal-design and exploration for non-motor vehicle system in urban center

With the recent social and economic development and the expansion of urban size, the demand for urban transportation has increased substantially, that introducing large amount of bikes and electronically-driven bikes and the traditional non-motor bike and motor vehicle operation conflict is significant. To this end, it is necessary to explore the operation characteristics of non-motor vehicle system, design and optimize road facilities, and establish a safe and efficient green non-motor vehicle system under the new situation. First, for the main participation mode in non-motor vehicle system, namely the conflict between electric bike and bicycle, and the limitation of sharing non-motor vehicle lane space, it proposes an optimal design for the mixed traffic flow of non-motor vehicles, recognizing the heterogeneity between electrified and the normal bicycles and offering detailed infrastructure plan on lane separation. Then, a quantitative approach then is proposed to evaluate the different plans of infrastructure design, based on a modified version of the analytic hierarchy process. Finally, a case study is carried out utilizing a real urban region in the city of Jiaozuo in China, analyzing its present situation and main problems, designing and evaluating the feasibility and rationality of the improvement plan. The comprehensive index value, as defined in this paper, the service quality of the non-motorized carriageway on a trunk road has been greatly improved by optimizing its design, indicating that the improvement is evident, especially more sustainable for mixed bicycle flow. This paper aims to provide a reference for the design of non-motor vehicle lanes.
