主讲人介绍:

聂宇博士,美国西北大学土木环境工程系助理教授。获清华大学结构工程学士学位,加利福尼亚大学交通工程博士学位。研究领域包括交通运输系统分析、交通仿真、交通流理论等。目前担任美国运输研究协会交通网路建模分委会、交通流理论特征分委会委员, Transportation Research Part B编委,国家科学基金审查小组成员。他的研究被国家科学基金、美国交通部、联邦公路管理局以及美国伊利诺州交通部所支持。

 

报告概要:

Transportation systems are affected by uncertainties of various sorts.  As a result, reliability has become a critical dimension in user experience of transportation services.  On one hand, lack of reliability either encourages overly conservative risk-averse behavior or leads to uncomfortable, sometimes disastrous, disruptions to personal and business schedules. On the other hand, users’ risk-taking behavior in presence of uncertainties may collectively affect the “equilibrium” of traffic in the system, and hence the design and operational decisions.

In this talk, a unified approach is proposed to model heterogonous risk-taking behavior in route choice based on the theory of stochastic dominance (SD), a tool widely used in finance and economics.
