用户均衡条件下3类停车设施收费定价模型

为了模拟多类停车设施运营(收费定价)竞争以及出行者的反馈行为,建立了基于用户均衡条件的路外、路内停车场和停车换乘设施等3类停车设施的收费定价模型.上层优化模型模拟停车运营者以利润最大为目标的停车费定价决策,下层用户均衡条件描述出行者以个人出行成本最小为原则的旅行选择行为,包括方式、路径和停车设施的选择.采用基于灵敏度分析的算法来求解该非线性规划问题.设计算例对模型和算法的有效性进行验证,结果表明:考虑多类停车设施运营竞争对停车收费定价最优解有显著影响,并且可能导致较低的停车收费水平和较好的交通需求管理效果,如人均出行的交通拥挤成本降低,停车换乘方式分担率提高等.     

Impact of the container security initiative on Taiwan's shipping industry

This paper evaluates the impact of risk factors from the container security initiative on Taiwan's shipping industry by employing a risk management matrix to identify the severity and frequency of CSI risk factors, and discovers some appropriate risk management alternatives. This paper's findings are as follows: (1) The majority of risk factors have a moderate-risk level, and possible alternative risk management measures include risk prevention, self-retention and insurance. (2) Ensuring a balance between the efficiency of maritime logistics and supply chain security is of vital importance to any trading countries dealing with security risk issues. (3) The government should encourage the private sector to design and market security hardware and software, which will promote the growth of the domestic security industry and generate employment opportunities.     

The impact of the Panama Canal expansion on Panama’s maritime cluster

The Panama Canal is currently in the process of a major expansion effort. After the new set of locks is opened in 2016, significantly larger ships can traverse the Canal. The current lock system has been in place for over 100 years, even though the size of ocean-going vessels has expanded considerably. One impact is on Panama’s maritime cluster. It is expected that the expansion will result in greater demand for many of the goods and services provided by the cluster. This article examines the economic impact of the Canal expansion on Panama’s maritime cluster. Clusters of economic activity can result in economies of agglomeration and supply chain network effects. Without these economies and network effects, clusters would not have a competitive advantage over businesses that are not in a cluster. It is expected that with a larger cluster, both agglomerative economies and network effects will increase. But, which cluster components will grow and which will not be affected to a great extent? To what extent will bottlenecks appear? These are some of the questions that this article addresses.     

A game-theoretical approach for modeling competitions in a maritime supply chain

ABSTRACT

To accommodate the structural changes in logistics, competitions along a maritime supply chain are more intensive than before. This paper adopts a two-stage noncooperative game-theoretical approach to model the horizontal and vertical interactions among liners and ports. In the first stage, Bertrand game is applied to model the interactions between two liners. When the shipping line decides which port to call, a multinomial Logit model is applied. In the second stage, Bertrand game is applied to model the competitions between two ports. Nash equilibrium is derived by solving the Bertrand games. A numerical example is provided as a case study.     

A review of recent theoretical and empirical analyses of asymmetric information in road safety and automobile insurance

Road safety policies and automobile insurance contracts often use incentive mechanisms based on traffic violations and accidents to promote safe driving. Can these mechanisms improve road safety efficiently? Do they reduce asymmetric information between drivers and insurers and regulators? In other words, is there residual asymmetric information in observed distributions of accidents and infractions? We answer these questions in this article by reviewing recent theoretical and empirical results that rest on various data and methodologies. We present recent tests related to the identification of residual asymmetric information in road safety management and in automobile insurance contracting. We also propose a theoretical analysis of the foundations of point-record driver's licenses observed around the world.

Importance of user perception in evaluating level of service for bus transit for a developing country like India: a review

Assessment of service quality in bus transit planning has received due attention in recent years from the viewpoint of optimal service allocation. The concept of level of service (LOS) has emerged as an effective tool to measure quality of services. Service-quality assessment provides operators with knowledge on users' satisfaction with existing services and their expected LOSs. The importance of user perception towards assessment of LOS has been acknowledged by researchers. While LOS standards for public transportation have been established by the Transportation Research Board in the USA, researchers have questioned the applicability of these standards in the context of different geographic regions. Since the service delivery environment differs between developed and developing nations, the user perception of service quality varies between these economic regions. Substantial research has been carried out in the context of both developed and developing nations, to identify the bus transit service parameters that affect users' perceived service quality; however, little research exists that establishes LOS thresholds for bus transit, based on user perception. This paper reviews the concept of LOS, describes the importance of user perception in assessment of service quality and identifies the need to establish LOS thresholds for bus transit from user perception for developing countries.
