Game Theoretic Formulations and Solution Methods for Transport Network Reliability and Robust Network Design

Robust Network Design

  • Project Team:
    • Principal investigators: Wai Yuen Szeto and Prof. Margaret O’Mahony
    • Research Student: Liam O’Brien

  • Description:
    • The contribution of the project is to significantly enhance the non-data driven deterministic framework of the game theory approach for analysing the network reliability. In doing so, superior models of risk-averse behaviour in route choice have been and will continue to be developed. These enhanced models will in turn be used in conjunction with the reliability measures developed to accurately capture the upper and lower bounds of the network reliability. This approach will be particularly suitable for the cases where there is little or no data on previous incidents in the network (which is very often the case). Furthermore the models of risk-averse behaviour developed in the thesis will be used to produce robust and reliable transport network design. Finally the project will provide a significant contribution to knowledge through the development of suitable solution algorithms which will allow for ease of implementation in practice.
