This paper analyses the rules for network access, the track access charging scheme and the problems of competition in the rail market. The focus is on regional rail passenger transport due to the fact that this is the most lucrative and promising market for new entrants. The main result is that in this segment in particular non-DB companies have increasingly used the chances which were opened by (paid) access to DB tracks and competitive tendering by regional authorities. However, although their market share has grown DB is still the major carrier. The failure to set an appropriate institutional and regulatory framework has proven to be the major obstacle to a more intensive competition in the rail market.</p></div>","PeriodicalId":100719,"journal":{"name":"International Journal of Transport Management","volume":"2 1","pages":"Pages 17-27"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ijtm.2004.05.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92972045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Models are evaluated for trips via a corridor and for a network system meeting a uniform trip demand.</p><p>The network transport model uses a grid-based synchronous system which could serve a whole city with a maximum of one transfer. This model has been proposed by others, but as far as is known no basic results have been published for its operational effectiveness. The analysis has provided a number of mathematical results for this system. The system proposed may have value in its own right, but is introduced to enable the effectiveness of meeting transport demand with transport networks of different density to be calibrated.</p><p>An interesting result, which may be new, is that the average trip length for uniform demand in a grid-based city is equal to one sixth of the city perimeter served, independent of grid density.</p><p>The results for the linear and network cases were found to be very similar. In both cases, average walk lengths are equal to average stop separation. Minimum trip times, including walk, wait, in-vehicle and transfer elements, were found to occur with a station separation of around 0.5<!--> <!-->km.

The favoured specification is a stock adjustment model augmented by a stochastic trend to allow for changing consumer preferences over modes of transport. Empirical estimates suggest that the future growth prospects for motorcycles may be quite good. This tentative conclusion follows primarily from what appears to be a significant, relatively high, long-run income elasticity of demand for motorcycles, combined with a high cross-elasticity of substitution effect with regard to a measure of the cost of motoring, which is dominated by the costs of buying and running a car. At the same time, our estimates indicate that these effects are subject to a countervailing tendency, represented by an on-going change in the public’s preferences away from motorcycles towards other modes of transport. Which of these tendencies will dominate in the motorcycle market over the next few years remains to be seen.</p></div>","PeriodicalId":100719,"journal":{"name":"International Journal of Transport Management","volume":"2 3","pages":"Pages 111-121"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ijtm.2005.04.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84506887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In developing countries, the trend of turning to the private sector for the provision of public transport services has resulted in a large number of individual operators whose main aim is (not surprisingly) to maximise profits. The drive for profitability can be achieved by increasing efficiency and cutting bloated costs, but may also lead to unfavourable behaviour that can adversely affect passenger safety and comfort and could also damage the urban environment. The challenge is to find a way to regulate and control this multiplicity of small businesses in such a way as to retain the cost minimisation pressures of the profit-seeking private sector without sacrificing safety, health or quality of service.</p><p>This paper presents a comparison of stakeholder attitudes to the regulation and control public transport in Dar es Salaam (Tanzania) and Faisalabad (Pakistan). The views of stakeholders were established as part of a wider DFID-sponsored study of ‘Partnerships to improve access and quality of urban public transport for the urban poor’ and were collected using content analysis, literature reviews, historical analysis, case studies, focus group discussions, forums and workshops. The stakeholders involved included users, particularly passengers from low-income households, providers and operators of services (drivers and conductors), and regulatory agencies. The example of the Faisalabad Urban Transport Society (FUTS), effectively a public–private partnership, is described to provide a useful model of regulation and control of private sector operators as well as for reconciling the interests of multiple stakeholders.</p></div>","PeriodicalId":100719,"journal":{"name":"International Journal of Transport Management","volume":"2 3","pages":"Pages 149-160"},"PeriodicalIF":0.0,"publicationDate":"2004-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ijtm.2005.06.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"98825444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
