Optimized Development of Urban Transportation Networks 2.0

Abstract

This report presents as series of eight papers on methods for planning, designing, and scheduling the implementation of improvements in urban transportation systems. Five of the papers (1 - 4 and 6) focus on methods for evaluating, sequencing and scheduling interrelated improvements in transportation networks while the others present methods for designing flexible route services (5 - 7) and improving the reliability of rail transit networks (8). Due to the complexity of the relevant functions for evaluating interrelated network improvements, which cannot be optimized with classical calculus techniques, the proposed methods rely on customized genetic algorithms for optimizing the selection, sequencing and scheduling of the interrelated alternatives. Applications to urban transportation networks are presented in papers for journals, which are included in appendices. The papers demonstrate the applicability of the developed methods to urban road networks, intersections in urban road networks, urban rail transit networks and flexible-route transportation systems.
