Ship finance and Euro-markets

Due to the capital-intensive nature of the modern shipping industry, loan finance plays a major role in vessel-acquisition cost. In this paper, J. B. Yolland discusses government-guaranteed finance, ancillary and commercial new building finance and finance for second-hand tonnage. He also examines a new source of funding found in the Euro-market.     

Techniques of land use/transportation planning in Australian cities

With the publication of the Sydney Area Transportation Study, land-use/transportation studies now have been conducted in all capital cities as well as in the majority of other urban areas with populations in excess of 40.000. A review of these studies is made and a qualitative assessment is attempted of the technical phases —land-use planning, trip-generation, trip-distribution, modal-split, traffic assignment and evaluation. Full summary results of this comparative survey are presented in tabular form, although themes developed in the text are illustrated with specific examples from individual studies. The methodology of land-use/transportation studies has been attacked by some Australian writers. An attempt is made to assess the relevance of these criticisms when applied to the practical planning process in Australia.     

Equilibrium holdings distributions in durable asset markets

The stock of durable goods can be represented by its holdings distribution, defined as the joint distribution of age and physical condition of the population of durable goods. This paper derives the holdings distribution which arises under stationary conditions when durable goods deteriorate according to a Markov process. We show that given the scrappage and utilization decisions of consumers, the holdings distribution F(x) is an equilibrium distribution of an associated regenerative Markov process. Using a basic result from the theory of regenerative stochastic processes, we characterize F(x) as the ratio of the expected number of periods the durable's condition is better than x to the expected lifetime of the asset. Using data from the 1977 National Transportation Survey we illustrate these results by estimating a simple two-parameter model of automobile deterioration and comparing the implied distribution of automobile holdings to the actual distribution.     

Bridge and tunnel toll elasticities in New York

In 1992, the authors carried out a statistical analysis of Triborough Bridge and Tunnel Authority (TBTA) crossings in New York City, to determine the impact of toll increases on traffic volumes and revenue. Using twelve years of monthly time-series data, we developed a set of multiple regression models that estimated traffic volumes on each TBTA bridge and tunnel as a function of the toll level and other explanatory variables. In most cases, the estimated toll elasticities were negative and much less than 1.0 in absolute value; the median toll elasticity for automobiles was found to be –0.10. Our finding that automobile travel demand is highly inelastic with respect to toll rates is consistent with most previous travel demand studies.

加拿大阿尔伯塔省经济的飞速发展，使得为全省制定合理的交通规划成为一项迫切的任务，在这种情况下，本文提出了全省的土地利用交通模型。该模型以PECAS（生产、交易和消费分派系统）结构为基础，实质是在整体经济的前提下考虑基本的交通需求（商品、服务、劳动力交换的流通过程）而进行交通规划。生产、交易和消费分派系统是一种空间经济模拟系统，它侧重交通规划和发展规划，近几年在美国提出并在一些州和城市得到应用。阿尔伯塔省土地利用交通模型受其模型建立基础，尤其是MEPLAN 和TRANUS模型的影响，但该模型在理论基础和行为描述上都做了明显的改进。本文从数据源和标定方法方面介绍加拿大阿尔伯塔省的土地利用交通模型的建立和发展。     

Understanding connectivity to international markets: a systematic review

Improving freight connectivity is increasingly a topic at the centre of the international trade and transport policy agendas. An examination of available documents and studies in both the policy-making and the academic fields shows that the concept of freight connectivity has often been defined in different ways, and thus has taken a variety of meanings. This poses the question on what connectivity is and what are its determinants in the context of international trade. We are not aware of any studies that have analysed, in a systematic way, the different perspectives and determinants of freight connectivity so as to increase access to international markets. This paper seeks to fill this gap by performing a systematic literature review that spans disciplines such as Transport Engineering, Transport and International Economics, and Supply Chain Management. The outcome of this examination is a multidisciplinary framework that hopefully will help stakeholders to understand freight connectivity to international markets better, as well as guide future research and analysis in policy-making.     

A new efficient EDI system for container cargo logistics

There have been many efforts to develop a logistics information system in the Korean logistics industry. In spite of these efforts, there are many points which need improvement in the Logistics Information System, of which function is the electronic data communication without added value. This paper aims to describe some of the main problems and the successful factors which are being found in the evolution of the present EDI systems for clearing import/export container cargoes, with special reference to Singapore, Korea, and Japan. Following this, leaving legal issues aside, to suggest workable guidelines for designing a new efficient EDI system for container cargo logistics. As a result of the review, the following successful factors are drawn: (a) the planning, requirement analysis and design of EDI are critical, as it provides a framework for its implementation; (b) as the data of customs clearance are an integral part of a logistics EDI system, the inclusion of customs in the system design is essential; (c) the sharing system of cargo data as the framework of the logistics EDI is efficient for data interchange; (d) the EDI software for the user has been developed and provided by an EDI network operating company; and (e) to facilitate communication between trading partners and the transport sector, it is necessary to adopt a global message standard, such as EDIFACT.
