Maritime connectivity and agricultural trade

Seaborne shipping is the dominant mode of transport in international trade in agricultural products, and an increasing part of seaborne agricultural trade is carried in containers. Furthermore, the majority of world containers are moved through liner shipping services, that is, regular transport services provided by global shipping companies which comprise a dense network connecting ports and countries around the world. Using a theoretically consistent gravity equation and a novel identification strategy based on the use of intra-national trade flows, this paper investigates the effect of liner shipping connectivity on international trade in agricultural products. The results show that liner shipping connectivity has a positive and statistically significative effect on agricultural trade. Moreover, this positive effect can be observed for the majority of the agricultural products analysed and is also identified for countries at different stages of development. These findings appear especially relevant in terms of the objective of increasing less developed countries' participation in global agricultural trade.     

Robustness of the air transport network

This paper presents a methodology for the detection of critical airports (those whose isolation would cause the largest losses in network connectivity) in the global air transport network (ATN), based on simulating an attack on selected ATN airports using different adaptive selection criteria. The performances of several node selection criteria are compared, together with a new criterion based on Bonacich power centrality. The results show that most critical airports can be detected with an adaptive strategy based on betweenness centrality. The detection of such airports may help the development of contingency plans to develop an appropriate response to any airport closure.     

The evaluation of demand responsive transport services in Europe

Over the last decade Demand Responsive Transport (DRT) services have grown in popularity for several reasons including: the shortcomings of conventional regular bus and taxi services; shortcomings of special transport services; and new developments in community transport. Traditional dial-a-ride services have often been criticised because of their relatively high cost of provision, their lack of flexibility in route planning and their inability to manage high demand. The potential for overcoming these limitations may be realised through the introduction of telematics-based DRT and this has been widely demonstrated, for example, in recent research funded by the European Commission (e.g. the DGXIII-funded SAMPO and SAMPLUS projects). This paper provides an introduction to the concept of telematics-based DRT services and presents the results of the evaluation of a set of DRT technologies and operations at urban and rural sites across Europe. The paper offers discussion in terms of the key issues that influence the introduction of DRT services.     

西安铁路枢纽客运系统扩能方案研究

西安铁路枢纽将有8个方向、7条铁路线引入,既有西安站已不能满足客流增长的需要。分析西安枢纽内影响客运能力的各项因素,结合西安枢纽的改扩建及西安城市规划,提出新建第二客运站——西安北站和辅助客运站——纺织城站,并对原西安站进行扩建的方案,形成西安枢纽客运系统二主一辅的格局。

三圃制与中古英国的运输革命

从12世纪开始，三圃制在英国的推广普及使得燕麦有了稳定的产量，加上套马技术的进步，从而为马在经济尤其是交通运输中发挥作用解决了饲料问题和技术问题。到13世纪中叶马已取代牛成为运输的主要畜力，14世纪马车已成为陆路运输的主要工具。中世纪英国的运输革命加速了经济的发展、促进了城乡之间的交流、加深了商品经济的复杂性、密切了农民与市场的联系。     

公路运输合同法律风险防范探析

探讨了公路货物运输如何从合同这个角度去规避风险,阐述了公路运输必须要认真对待合同的订立,合同必须条款完备,责任期间及权责的划分要明确。同时,执行合同一定要严格把关,尤其是接货与交货阶段,以杜绝法律风险的发生。
