In order to achieve an efficient transportation system, proper demand management strategies are more critical than increasing facility capacity. Previous studies suggest that most of the strategies have substantial impacts on traffic pattern and travel behaviors, but the effects may not be exactly the same as they were initially expected to be. This project focuses on assessing travel demand management strategies to enhance such understanding. Among the existing research, users’ behavior in freight transportation is relatively under-investigated, because the empirical data collection is difficult. Therefore, this project fills the void by analyzing exclusively on freight carriers’ behavior changes in response to freight travel demand management strategies. A survey was conducted and a regression model was established to provide important insights into the behavior problem.
