Author Description

In recent decades, tolling has been implemented in many highways, bridges, and tunnels for generating revenues for construction, management, and maintenance. To setup tolling scenarios, traditional methods, such as surveys and public hearing, are time and cost consuming. In addition, there likely have various impacts for the different levels of toll. However, there is a lack of handy tool for analyzing the impacts of time-of-day tolling on roadways. Therefore, the purposes of this project are: 1) propose a model to capture the relationship between the time-of-day toll and route choice; 2) develop a TOD analysis software that is convenient for quickly evaluating the impacts of various time-of-day tolling scenarios; 3) easy visualize traffic flows on roadways through different toll rates; 4) and graphically illustrate the revenue, monetary savings, travel times, speeds, VHT, VMT, and welfare from the results. The TOD analysis pack can help to reduce drastically the time and effort in analyzing the costs and impacts of any time-of-day tolling project. It also provides a convenient and flexible tool for testing the impacts of various tolling scenarios for any highway. The visualization features can illustrate the diversion of traffic due to tolling implementation, and can display the top-ten most impacted roads. The TOD analysis pack can seamlessly be jointed-up with the existing TransCAD models that already exist at INDOT. Moreover, the application can be integrated with Google Maps, which provides additional information for users.
