Product Description: Contains up-to-date and accessible material, plus all the necessary mathematical background. By verifying the asymmetric property of the dynamic link travel time function, while identifying the inflow, exit flow and number of vehicles on a physical link as three different states over time, the author adopts a variational inequality approach using one time-space link variable...read more

Modelling Transport J. de D. Ortúzar Pontificia Universidad Católica de Chile, Santiago, Chile L. G. Willumsen Steer Davis Gleave, London, UK This is a crucial time for transport planning and policy making, and investment in these areas is increasing. This book presents a unique contemporary account of key transport modelling techniques and applications. The authors identify methods of responding to current pressing transport planning issues and problems, reflecting radical innovations from which transport modelling techniques have benefited in recent years. Guidance is given on model selection, development, adaptation and application in different contexts. The treatment is accessible to students and practitioners alike and the subject is approached as a modelling exercise with discussion of the roles of theory, data, model specification, estimation, validation and application. Techniques are included for selecting the right level of analysis and detail for modelling purposes and how to adapt existing tools to serve the needs of regular updating of models and plans. Appearing soon after the first edition, this second edition is completely updated and presents strengthened material on Stated-Preference Techniques. The book will be useful for practitioners and both graduate and final year first degree students in civil engineering, geography, transportation and planning.
