We analyze market shares for each public transport mode in total public transport ridership for the multimodal public transportation system of Athens, Greece. This analysis provides useful information for making investment decisions concerning the public transport infrastructure and for allocating subsidies. Due to the non-stationary properties of the data, cointegration techniques are applied to investigate the long run equilibrium relationships. Error Correction Models are implemented to estimate short run dynamics as well as the speed of adjustment from the short to the long run. Results suggest that fare and GDP are the main determinants of the public transport mode shares both in the short and in the long run. Findings also indicate the role of total ridership fluctuations in explaining variations in public transport mode shares. 相似文献

In Sub-Saharan Africa (SSA), inland export transport costs and time delays are much higher for landlocked countries, vary substantially between different geographic corridors, and exhibit substantial uncertainty. Unit costs and costs of time for land transport of exports are high for many agricultural products relative to metals and other high-value products. We illustrate systemic uncertainty in land and maritime transport for exporting by use of simulation. Relationships among uncertainty, infrastructure quality, and other features of logistics systems are highly non-linear, and can be potentially used to identify priorities for trade facilitation. 相似文献

CY Tung was the pioneer of innovation and the practioner of innovative theories in modern shipping, regardless of his huge oil tanker building, container transport, institutional management or resource integration. Tung, the shipping industry have called the pioneer of innovation, Tung's road to success is a story and history of continuous innovation. In his shipping career, adhering to the innovative concept, multi-use new shipping technology, and management practice, Tung had built a team with the ability to innovate. Tung's group, by integrating its human resources, contacts and production resources ultimately established himself in the highly competitive international shipping market and achieved his legendary of the world shipping tycoon. 相似文献

Stronger demand for medium- to long-haul air transport is the main driver of the tourism industry's increasing greenhouse gas (GHG) emissions, causing the current development of global tourism to be environmentally unsustainable. Efficiency improvements and biofuel usage are unlikely to maintain pace with the projected growth in transport volume. Therefore, curbing the growing demand for air transport has been suggested as another option for the sustainable development of tourism. However, the political and industry discourse concerning the restriction of air transport tends to label such a restriction as unethical, as such limits would impair the development that tourism brings to poor countries. This paper investigates the possible impacts of air travel restrictions on the least developed countries (LDCs) and non-LDCs by examining global tourism. The impacts on LDCs are found to be ‘neutral’ on average, with both losses and gains in tourist arrivals. The extent of any losses does not appear to be beyond the scope of possible economic compensation. 相似文献

This paper critically examines the methods of transportation used by independent tourists and how importantly they value mobility throughout their journeys. While independent tourists are frequently identified as being adventurous and highly mobile, relatively few researchers have critically examined the modes of transport they use or the importance they play in enhancing and fulfilling their desired experiences. Indeed, most literature portrays independent tourists as habitual users of public transport as opposed to modes of personal transport. In this paper, the notion of automobility – a combination of autonomous and self-directed movement – is explored from the perspective of independent tourists in Norway. A multi-method qualitative study was undertaken which analysed the views of 38 independent tourists at eight different locations. The findings revealed that personal modes of transport were intrinsic features of the journeys undertaken and that they offered alternative sensory experiences in contrast to public transport. Moreover, for many independent tourists, autonomous journeys were considerably more important than the destinations they visited. Thus, for many independent tourists in Norway, demands for control, flexibility and adventure could only be satisfied by using particular modes of transport. 相似文献
