Abstract

This chapter is the first thorough assessment of a full implementation of the concept of dynamic traffic management in combination with advanced optimization tools. In the last years, several studies on partial implementations of: this concept have been carried out reporting promising results. The development of new strategies for railway traffic control experienced an increasing interest due to the expected growth of traffic demand and to the limited possibilities of enhancing the infrastructure, which increase the needs for efficient use of resources and the pressure on traffic controllers. Improving the efficiency requires advanced decision support tools that accurately monitor the current train positions and dynamics, and other operating conditions, predict the potential conflicts and reschedule trains in real-time such that consecutive delays are minimized. We carry on our study using an innovative computerized railway traffic management system, called ROMA (Railway traffic Optimization by Means of Alternative graphs). An extensive computational study is carried out, based on two complex and busy dispatching areas of the Dutch rail :network. We study practical size instances and different types of disturbances, including train delays and blocked tracks. Our results show the high potential of ROMA as a support tool to improve punctuality through intelligent use of the rail infrastructure and efficient use of the available transport capacity.
