| Over recent years, as the market of transportation of passengers grows more and more mature, the competition among all kinds of transportation of passengers is becoming increasing fierce and the railway transport is facing a growing serious situation. There are two reasons accounting for this. On the one hand, objectively, other types of transport are developing rapidly. Their transport abilities are largely enlarge and service quality highly improved. Therefore, they appeal enormously to a great number of passengers. On the other hand, subjectively, there exist many incompatibilities in railway transport itself with the market. The whole competence leaves a lot to be desired, especially that the quality of transport service is not perfect enough, far from being able to satisfy the great number of passengers.Transportation ability calculation is based on the relation between transport demand and transport supply, that is to say, transport demand and supply analysis is the basis of ability calculation and its application. The theories and methods will be quite different when transport ability is calculated from the aspect of quality, the combination of number and quality respectively. Following will be the analysis of the reasons affecting service quality, the service classification of transportation capacity of special passenger into transport transport special line, the calculation of transportation capacity when taking into consideration service quality. Besides, there will be experimental calculation analysis and evaluation of Beijing-Shijiazhuang passenger transport special line. |
