讲座嘉宾 简介
Ronghui Liu (刘蓉晖) is Professor in Traffic Network Modelling and Transport Operations, at the Institute for Transport Studies (ITS), University of Leeds. Her research span a number of areas in transport data and modelling: from traffic flow modelling and microsimulation, traffic network modelling, public transport (including buses and trains) timetable optimisation and real-time control algorithms, to more recently in applying AI/ML in developing data-driven methods for the optimisation and control. She has been elected as a Fellow of the Turing Institute, the UK’s national institute for data science and AI, an Associated Editor of IEEE-ITS and Deputy Editor of Journal of Intelligent Transportation Systems. Since 2021, she has also been the Director of Research for ITS, the 2nd largest academic unit dedicated to transport research and education in Europe.
讲座概要
In this study, we consider a rational inattentive (RI) route choice problem. Since a computational challenge, called curse of dimensionality, always arises in the existing route-based RI choice models. We establish a RI choice model by link-based segments, where the RI choice behaviour is learnt along the links instead of the routes. We introduce the background information into the RI choice model, which ensures its optimal solution locates within the interior of the feasible region. We then analytically characterize the closed-form expression of the optimal solution, which resembles a nested logit model. Finally, a numerical example is illustrated, showing that the solution algorithm can identify the RI route choice behaviour within a reasonable computation timeframe.
