On 12th July,2017, in Room A716 of the New Main Building, Associate Professor Xiaolei Guo,from Windsor University, was invited to make a lecture on “Profit Maximizationby a Private Toll Road with Cars and Trucks”. The lecture was hosted byprofessor Tian Qiong and more than 30 people attended, including professors and students from School of Economics and Management, Beihang university.

The profit maximizing behavior of a private firm which operates a toll road competing against a free alternative in presence of cars and trucks is a common phenomenon. He found that the firm takes either a car-strategy or atruck-strategy for profit maximization. For a traffic mix with relatively large car volume and small truck volume, the car-strategy results in no trucks using the toll road, while the truck-strategy results in all trucks using the toll road. He then considered mixed travel behaviors of cars and trucks in that trucks choose routes deterministically, while cars follow stochastic user equilibrium in route choice. He found that, depending on the per-truck pavementdamage cost, the firm may take a car-strategy, a truck-strategy, or a car-truckmixed strategy.

After thelecture, associate professor Xiao Lei Guo conducted further discussions with the audience.
