Intelligent transport systems solutions in transitional countries: The case of Korea

Transport policy in Korea is driven by the need to cope with ever-worsening traffic conditions. The development of an intelligent transport systems (ITS) Master Plan for Korea is of particular interest and demonstrates the heavy reliance placed on ITS measures to facilitate both the management of congested (but expanding) highway networks and to encourage a shift to greater use of public transport. The paper highlights the major achievements of ITS in Korea by assessing the evidence provided by the widespread implementation of ITS technologies (such as the creation of 'showcase' demonstrations). Some observations from the implementation of ITS in (so-called) transitional economies are presented.

The effects of US shipping regulation on specific aspects of liner conference operation

This paper is the first of two articles by J. E. Davies which seek to explore the incongruities of the USA's current regulatory system. The second paper will cover the overall economic impact of the USA's insistence on open conferences in its trades, whilst the first concentrates on the effects of US regulation on specific aspects of the operation of linear conferences.     

The competitive environment of liner conferences

Although liner conferences are traditionally assumed to possess effective monopoly power, such a view ignores many important aspects of their competitive environment. This article examines some of these neglected competitive features and shows how they may decisively influence conference pricing strategies.

In the analysis of linear shipping, the notion that conferences are effective monopolists lies at the root of many of the grievances of the conference system. It has also become an integral part of the conventional wisdom of shipping economies, to such an extent that the monopoly power of conferences is virtually regarded as a matter of established fact rather than what it really is-namely a postulated assumption open to testing and refutation.

It is the purpose of this paper to explore the competitive conditions of the industry in which liner conferences operate and to try and establish the extent and limitations of their market power. This will involve an analysis of hte bariers to entry which conferences may be protected by, the manner in which the relevant industry should be defined, the possibility and consequences of new entry, and the response of conferences to their competitive environment.     

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.     

机动性是可持续的吗?

可持续的机动性是指,在不破坏地球和其生态环境的前提下,利用可再生能源为人类和货物提供安全可靠的自由运输。为了可持续,机动性必须从＂我们现有的技术＂出发去进化。必须制定尽可能长远的方针政策,而不应该把焦点仅仅集中在短期的解决办法上!     

On the nature and sorces of controversy in the economic analysis of the liner shipping industry†

The simulations performed show that demand for quality tankers has to increase by 30% for a two-tier tanker market to emerge. The two-tier freight structure will only last for 3–5 years due to contracting induced by higher freight rates. This means that OPA does not by itself result in higher freight rates for tankers that comply with the requirements. If Western Europe also closes their trades to substandard tankers, a two-tier market emerges and quality tankers obtain a premium. The paper presents a simulation model for international tanker markets. The non-linear complementary equilibrium model solves for a sequence of static equilibria in segmented tanker freight markets, shipbuilding and scrapping markets. Freight markets are segmented according to quality requirements for tankers. The model specifies three tanker classes and one—quality tankers—can operate both market segments.     

Cycle Network Planning: Towards a Holistic Approach Using Temporal Topology

ABSTRACT

Current cycle-network planning (CNP) at the local level tends to be dominated by a subjective-pragmatic approach in which it is only possible to consider a limited number of route alignment possibilities and development-sequencing scenarios. Although this method may produce acceptable results, it may also be true that the final design could be improved – and the construction efficiency could be enhanced – by a more comprehensive review of the available options in relation to the objectives of the intervention. Such objectives may include accident reduction, modal shift in favour of cycling, health benefits or strategic expansion of a network. This article presents work undertaken to demonstrate a holistic approach to CNP, based on a logically defined spatio-temporal model and allowing some semi-automated multiobjective optimization of network designs in a GIS-based decision-support system. The model is introduced briefly before a case study applying this model to development of a cycle network in a small town in northeast England is described. The results obtained from this case study and the implications of this research for cycle network planners are discussed.
