Estimation of origin‐destination matrices for a multimodal public transit network

This paper presents a procedure for the estimation of origin‐destination (O‐D) matrices for a multimodal public transit network. The system consists of a number of favored public transit modes that are obtained from a modal split process in a traditional four‐step transportation model. The demand of each favored mode is assigned to the multimodal network, which is comprised of a set of connected links of different public transit modes. An entropy maximization procedure is proposed to simultaneously estimate the O‐D demand matrices of all favored modes, which are consistent with target data sets such as the boarding counts and line segment flows that are observed directly in the network. A case study of the Hong Kong multimodal transit network is used to demonstrate the effectiveness of the proposed methodology.     

港口腹地划分的两种新方法探讨--以大连国际航运中心为例

引入经济地理学的新理论成果———圈层结构法和点轴法,提出了圈层结构划分法和点轴结构划分法两种新的港口腹地划分方法,并应用这两种新方法对大连国际航运中心港口腹地范围的界定与划分进行实例分析。与以往的行政区划法、经济区域法等港口腹地划分方法相比,这两种方法更加注重对港口原有腹地的细分,更接近于港口腹地的实际状况,进而有利于港口企业的经营发展。     

从国际海运企业购并效益谈对我国的启示

购并是企业实施外部发展战略的常规策略，在进入和退出壁垒均较高的国际海运业，购并成为形成国际性经营联合体及市场领导企业的重要途径。通过购并，国际海运市场的集中度越来越高，呈现出多寡头垄断的市场格局。购并带给海运企业的最大效益是实现了规模经济，同时还提高了购并企业的融资能力，为企业提供了获取先进技术和优秀人才的渠道，并使企业可以享受税收上的优惠。国际海运业的购并历程为正处于高速发展阶段的国内海运业提供了良好的经验借鉴。

Development and Deployment of Public Transport Policy and Planning in Taiwan

Over the past decade, the escalating roadway congestion and environmental deterioration due to heavy use of private vehicles have provoked the Taiwan government to realize the importance of public transport systems. Under the “carrot-and-stick” rationales, the government has formulated public transport policies and exercised a series of related initiatives by providing sufficient and higher quality of public transport services so as to attract more private vehicle users. In this paper, the planning philosophy and policy formulation of Taiwan’s public transport development are highlighted. The most important initiatives, including the Five-year Enhancement of Mass Transportation Program and the upgrading public transport schemes in the National Development Plan are examined. Based on previous experience and lessons, we point out the most challenging issues that the government will encounter. Suggestions for the future of public transport planning are also addressed.

Driver requirements and road traffic informatics

Initially the driver's role as a link in the driver-vehicle-road-traffic control-chain is discussed in a historical perspective. The gradual changes and the advantages and problems arising from these changes are discussed from behavioural point of view.Then the driver tasks are analyzed. A separation is made between trip planning, navigation, road following, traffic interaction, rule compliance, other than traffic tasks, car handling and speed choice. The relations between and the weights of these subtasks are discussed. Some existing driver behaviour models are reviewed in relation to the above mentioned tasks.Finally an effort is made based on the analyses of driver tasks and driver models to specify some general and some more specific potential advantages and problems with expected future RTI-systems.
