In this seminar, I would like to present two of my papers, my bachelorís thesis and masterís thesis respectively, regarding route choice model and algorithm. The title of bachelorís thesis is ďcomparative study of Logit-based network loading algorithmsĒ, which concerns analytical and numerical comparisons of traditional STOCH algorithm and Topological-scan based Logit algorithm (T-Logit). Analytical study shows that T-Logit is more accurate than STOCH. Detailed numerical experiments illustrate how Logit parameter influences the loading result. My research topic of masterís thesis is ďroute choice behavior modeling with travel time reliability requirement under uncertain demandĒ. Mixed-strategy is employed to model travelerís route choice behavior, which also considers travelerís travel time reliability requirement when they face an unreliable traffic network. Demand uncertainty is the source of unreliability. An understandable and resolvable SUE mathematical program is constructed. The model can be easily extended to multi-class user type and numerical examples can prove its validity.
