老城区停车改善方案研究——以C市为例

为促进老城区停车系统良性发展,本文调查C市老城区停车现状,基于停车需求分析,在静态交通良性发展框架基础上,针对现存主要问题提出停车设施改善措施,推动构建“配建为主、路外为辅、路内补充”的停车系统。分析结果表明,通过增量供给约4000个固定停车泊位,可解决67%的停车泊位缺口;利用老城区更新用地12.65公顷建设公共停车场可有效缓解停车供需矛盾;推广公建类建筑夜间停车共享,可为老旧小区提供约1310个夜间泊位,满足居住区夜间停车需求。研究结果为停车设施建设优化提供一定参考,并为行业管理提供理论依据。

中心城高校校园静态交通系统的规划设计研究——以上海交通大学徐汇校区为例

为缓解我国校园的静态交通问题,以上海交通大学徐汇校区为例,通过调研校园停车特性以及现状停车问题,在对停车预测基础上,提出了适合校园静态交通系统的发展策略和规划布局,并提出了开发利用体育场地下空间资源解决校园停车难的规划方案,净化地面交通,保护校园环境。研究可为未来其他高校的静态交通系统规划设计提供参考。

Sensitivity analysis method for increasing the passenger demands of parking and riding

Focused on finding out the relationship between passenger demands of P&R and its influencing factors, a nested-logit mode choice model was developed based on the characteristic of different modes and transfer rules. The utility functions were given respectively according to the characteristic of each alternative. Passenger demands of different modes between O-D pairs were obtained by making use of the binary logit model. Then an equilibrium model for different modes was proposed. Under this condition, the approximate relationship between passenger demands of different modes and their characteristic indexes was modeled by the sensitivity analysis method. Shift volume among different modes was achieved by utilizing this model when their characteristic indexes were changed. A case study indicates that the model and algorithm presented in this paper are effective.
