| ABSTRACT Egypt Government decided to implement a new advanced Railways Tracking and Control System (RTCS). The main aim is to protect the citizen’s (passengers) life, future, and business through achieving quick trains-conflict detection, and resolution, short response times in the event of disasters and other operational disturbances, and elimination of most or all “human factors” trains accidents. TRCS can also overcome the problem of railways traffic congestion which has increasingly become a major economic barrier to the flow of goods across the country. A team has been dedicated for the Egyptian RTCS project where the system investigation, data gathering, feasibility study, data analysis, system design phases have been accomplished and the project is now in the real implementation phase. The new advanced RTCS combines real-time rescheduling with an advanced train control tool. The system is designed to increase railway network capacity and stability in heavily used mixed traffic networks while minimizing the cost of building new railway infrastructure. The system combines real-time rescheduling, train control, and a new strategy for train operations into a coordinated Main Control Center (MCC) for traffic management. This approach is based on saturated use of network capacity bottlenecks, which is implemented by ensuring that MCC and every train always have up-to-date, conflict free schedule containing time, and speed and route information. The implementation of the Egyptian RTCS shall provide the input data about the railway subsystem (i.e. stations, locomotives, trains, trips…etc) that help in modeling the RTCS. The objectives of the modeling are to assign the fleet of locomotives to a network of trains while satisfying a variety of trips constraints and minimizing the total economic cost. The research on the modeling of railways transportation include scheduling theory, graph theory, mathematical programming, operational theory, and some have addressed the problem of traffic controlling from multiple levels’ points of view. In this paper, RTCS planning is formulated as Mixed Integer Programming (MIP) problem. The modeling network is a weekly space-time network where arcs denote trains, nodes denote events (arrivals and departures of trains at terminals), and different locomotive types define different commodities. The objectives of this paper are to present the building of Egyptian RTCS project effort and to emphasis on the benefits of implementing this project as well as to present the use of integer MIP techniques for modeling such an RTCS. | ||
