Travel demand prediction under non-recurrent situations

A fantastic topic. The goal is to predict travel demand under non-recurrent situations based on normal historical data. I have developed a model for metro systems.

Intelligent Transportation System Planning

A extreme practical topic. Intelligent transportation system planning based on consideration of smart connected vehicles. The V2I roadside environment design and the coordinated traffic signal control/traffic guidance system design are included.
