北京市郊铁路建设优化探讨刘小平

建设京津冀环渤海轨道交通“一小时经济圈”对于实现京津冀经济一体化具有重要意义。根据城市规划及北京市城市交通特点,借鉴国际轨道交通特别是市郊铁路建设运营的经验,明确交通经济圈分层结构,提出在发展完善地铁网和高铁网的基础上,因地制宜,近远结合,充分利用既有铁路资源,建设S1至S7数条市郊铁路,并通过综合客运交通枢纽形成“三张网”有机联系,实现综合运能最大化的设想。     

CONSUMER DIRECT FULFILLMENT PERFORMANCE IN INTERNET RETAILING: EMERGENCY TRANSSHIPMENTS AND DEMAND DISPERSION

The collaborative fulfillment of consumer orders by Internet retailers and wholesalers has proven important in the realization of sustainable levels of online profitability. Concentrating on consumer direct fulfillment (or drop shipping), an empirical simulation model evaluates avenues for improving logistical performance. The empirical simulation model centers on the online music CD retailing industry. It evaluates the effects of emergency transshipments and demand dispersion on inventory and product‐release performance, as well as on transportation costs, in consumer direct fulfillment operations. Results show that emergency transshipments improve inventory and product‐release performance in these operations. Furthermore, the inventory‐performance improvements are maximized when inventory facilities fulfill demand that is uniformly balanced across markets primarily assigned to each facility. Finally, gains in inventory and release performance obtained from emergency transshipments outweigh additional transportation costs incurred from a greater reliance on emergency transshipments for consumer direct fulfillment.

Use of mathematical models in automotive transportation policy analysis: A case study

Mathematical models are used widely in automotive transportation policy analysis. The limitations, benefits, and uses of a case-study model, the Sweeney Passenger Car Gasoline Demand Model, were examined. It was found that because of users' lack of awareness of the model's characteristics, the model has sometimes been misused, although the misuse appears to have had no major negative policy impact. However, the model use has had some impact on major automotive/energy policy decisions of the 1970s. Involvement by the model author in applications of the model contributed to effective use of the model in the policy process.     

Parking futures: An international review of trends and speculation

The explosion of low-cost, on-demand taxi services and the anticipation of an autonomous vehicle future has made transportation the center of debate and discussion for the first time since the massive expansion of the US highway system in the 1950s. Yet the realm of parking boasts innovations and developments far beyond the high-profile issues of TNCs and AVs. Rather, innovation in parking is happening in many cases quietly on a wide variety of fronts, including technology, public policy, and design. This paper serves an overview of emerging trends in parking, primarily within the US context. We identify and outline five developments and the pertinent technologies helping to catalyze change: unbundling parking costs, reducing parking minimums, pricing and allocating curb space dynamically, designing hybrid parking structures, and preparing for the autonomous era and “mobility as a service.” This paper presents these trends with illustrative examples highlighting current practices, governance challenges, and possible future scenarios.     

浅谈湖北省出租汽车客运市场存在的主要问题及原因

湖北省出租汽车客运发展到目前,已成为道路运输和城市公共交通的重要组成部分,是一个非常重要的“窗口”行业,倍受各级政府、社会各界和广大人民群众的关注。出租汽车客运,是指用小型客车按乘客意愿提供运送服务,并按行时里程和时间计费的道路旅客运输经营活动。湖北省出租汽车客运行业的发展从二十世纪初出现第一辆出租汽车开始,经历了一个从无到有、由少到多、由弱到强的发展历程。

基于库存理论的铁路始发直达运输产品设计

将库存理论运用到铁路始发直达运输产品设计,能够有效实现运输服务组织成本与库存成本的有机统一。为实现库存成本在铁路始发直达运输中的加载,在考虑周期非完整情况下的库存成本的同时,将铁路运输和库存成本纳入同一目标函数,在装卸车地库存能力约束下,构建基于库存理论的铁路始发直达运输产品设计模型,确定成本最小的铁路始发直达运输产品设计方案。以赤峰地区至山东省煤炭运输网络为例,设计方案有效降低了成本,有助于吸引客户选择铁路运输,以及辅助铁路运营单位研究调整始发直达运输产品方案。
