aIntegrated system planning for railways J. Dreier, U. Brockmann IWIngenieurgesellschaftfur Verkehrsplanung und Verkehrssicherung GmbH, Obergstrasse 5, D-38102 Braunschweig, Germany Abstract Integrated System Planning (ISP) is a method for optimizing long-term assignment of railway passenger carrying capacity to passenger demand. The three goals of ISP are (1) to increase the market share of railway passenger transportation (strategic area), (2) to balance passenger load on trains by coordinating regional and long-distance traffic to arrive at optimized timetables (capacity area) and (3) to lower production cost by integrating production planning to optimize rolling stock and personnel assignment (resource area). ISP and railway operations are supported by compatible software packages that eliminate manual data reentry. 1 Introduction Integrated System Planning (ISP) is a multi-step hierarchical process as shown in Figure 1 comprising • Passenger Demand Det
