In this article, multiple-product PVRP with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. A mathematical formulation was provided for this problem. Each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. To solve the problem, two meta-heuristic methods...

Passenger flow forecast is of essential importance to the organization of railway transportation and is one of the most important basics for the decision-making on transportation pattern and train operation planning. Passenger flow of high-speed railway features the quasi-periodic variations in a short time and complex nonlinear fluctuation because of existence of many influencing factors. In t...

A major problem addressed in railway network planning relates to distinguishing the role of the railway line in the network, and making a reasonable classification of the lines based on their role. Accessibility has been widely used to measure the role of transportation infrastructure in various studies, but few quantitative models for the classification of the role have been presented yet. In ...

In recent years, some sadly famous terrorist attacks that occurred in different countries have put into evidence that railway transportation systems are not suitably protected, and not capable of tolerating and promptly reacting to them. Moreover, it is clear that such mass transportation systems are particularly attractive for terrorists, due to the potentially far-reaching, often “spectacular...

On the basis of study of domestic and foreign experts, according to the existing energy structure and present status of transportation industry, comparing and analyzing the energy consumption and low-carbon economy indicators of different modes of transportation, this paper put forward the thinking of constructing low-carbon comprehensive transport system, which takes railway as main and also c...

Recently, social environment rapidly varies and it affects the trend of social infrastructure. Railway transportation which is typical social infrastructure is also affected by this trend. To meet this situation, the railway system needs a capability for gradual and short-term extension. To realize these requirements, an autonomous decentralised software architecture is proposed and its practic...

To satisfy the growing passenger transportation demands and improve the service quality in railway system, a more stable and robust timetable needs to be designed while considering highly utilized capacity. Acyclic timetable is extensively applied in large railway networks. In order to acquire the quality of timetable, analytical timetable stability analysis software PETER (Performance Evaluati...
