Logit algorithms� comparisons and Route choice modeling with reliability requirement

In this seminar, I would like to present two of my papers, my bachelor�s thesis and master�s thesis respectively, regarding route choice model and algorithm. The title of bachelor�s thesis is �comparative study of Logit-based network loading algorithms�, 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 master�s thesis is �route choice behavior modeling with travel time reliability requirement under uncertain demand�. Mixed-strategy is employed to model traveler�s route choice behavior, which also considers traveler�s 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.
