Identifying Governance Relationships Between Intermodal Terminals and Logistics Platforms

Abstract

Governance theory examines different ways of managing resources and relationships in order to achieve a desired outcome. This paper applies governance theory to intermodal terminals and logistics platforms, extending previous work on ownership to include different operational models. An inductive methodology is used to derive a typology of governance relationships from an analysis of the transport and logistics literature. The classification developed in this paper explores different kinds of integration that can help support growth of intermodal transport services. The understanding of transport governance is extended via three key relationships: first, between the logistics platform and the site tenants (therefore, encouraging consolidation and efficiencies that can boost rail services at the site); second, between the terminal operator and rail service provision (which can aid service planning and train loading factors); and third, between the inland site (either terminal, logistics platform or both) and port(s), (thus enabling better planning and efficiency of port rail shuttles).     

Integrated smart feeder/shuttle transit service: simulation of new routing strategies

The idea of designing an integrated smart feeder/shuttle service stemmed from the need to overcome the problem of using an excessive number of cars arriving and parking at a train station within the same time span. This problem results in high parking demand around the train station. Moreover, some potential train riders will, instead, use their cars and hence become a party to increasing the traffic congestion. This work develops a new idea of an integrated and innovative feeder/shuttle system with new operating and routing concepts. The fulfilled objectives are as follows: (i) to construct and examine different operating strategies from both the user and operator perspectives; (ii) to examine different routing models and scenarios; and (iii) to construct a simulation tool for (i) and (ii). Ten different routing strategies are examined, with all the combinations of fixed/flexible routes, fixed/flexible schedules, a unidirectional or bidirectional concept, and shortcut (shortest path) and/or short‐turn (turnaround) concepts. These strategies are investigated by employing a simulation model specifically developed and constructed for this purpose. This simulation model is used in a case study of Castro Valley in California in which the feeder/shuttle service is coordinated with the Bay Area Rapid Transit service, and the 10 routing strategies are compared in regard to four fleet‐size scenarios. One of the interesting results found is that the fixed‐route and flexible‐route concepts are comparable in performance measures when applying a combination of operating strategies.

Evaluating Flexible Transport Solutions

Abstract

Flexible transport services (FTS) have been of increasing interest in developing countries as a bridge between the use of personal car travel and fixed route transit services. This paper reports on findings from a recent study in Queensland Australia, which identified lessons from an international review and implications for Australia. Potential strategic directions, including a vision, mission, key result areas, strategies, and identified means of measuring performance are described. Evaluation criteria for assessing flexible transport proposals were developed, and approaches to identifying and assessing needs and demands outlined. The use of emerging technologies is also a key element of successful flexible transport services.     

基于CAE分析的某车型发动机舱内饰优化设计

针对某车型发动机舱内多个零部件发生烤焦和烤化问题,根据CAE对整车爬坡工况时机舱内空气流动状函分析结果,得出此问题是由发动机舱进风量不足、发动机舱前部和后部存在空气热回流等现象所引起的。文章通过增加散热器导风板、修改前保险杠上部装饰板和发动机底部护板等措施,使总进风量提高了5．6％,发动机舱后部靠近前围外隔热垫温度明显降低。改善了发动机舱的内流状况,为后续的机舱内饰设计提供了新的思路和方法。     

交通拥挤收费空间公平性探讨

将出行者按照时间价值（VOT）和地域划分为不同群体,在一个简单路网上建立交通网络模型,分析拥挤收费的公平性影响.研究模拟居民的多种不同出行选择,分析了实施拥挤收费对两处居民各类人群在出行方式分担、行程时间以及交通可达性等方面的影响.研究发现,对于始发地居民,引入拥挤收费能够降低其行程时间,提高可达性;而对于周边道路沿途的居民,若周边道路通行能力不高,适当的拥挤收费会提高可达性,若周边道路通行能力较好,拥挤收费则会小幅度的减少其交通可达性.
