I80/94 Expressway Traffic Simulation for Transportation Planning

Freight Reliability Simulation and Visualization 


THE PROBLEM

Visualization of Borman Expressway

Visualization of Borman Expressway

The Borman Expressway is a sixteen mile segment of interstates 80 and 94 (I-80/94) and is part of the Gary-Chicago-Milwaukee corridor. It begins at the Indiana/Illinois border and stretches east to the Indiana toll road interchange. The average daily traffic (ADT) on the Borman is approximately 140,000 vehicles, with freight comprising about 30% of the traffic on average and peaking at 70% at night. Traffic volumes are relatively constant from the morning through the early evening, with near or at capacity volumes during most daylight hours under perfect operational conditions. The purpose of this study is to measure the economic effects of the interaction between congestion and freight mobility across Northwest Indiana. 


THE PROJECT

Traffic Visualization from real time data

Traffic Visualization from real time data

By utilizing the visualization and simulation resources at Purdue University and through collaboration with the Center for Innovation through Visualization and Simulation (CIVS) at Purdue Calumet, this study will contribute to the general body of knowledge of how visually enhanced applications can enrich the existing transportation system database to effectively measure benefits and costs associated with improvement in freight transportation. Visualization applications in freight transportation can help to gain insights into effective solutions. 


THE RESULTS

Results from traffic simulation

Results from traffic simulation

The results from this synthesis study will provide the transportation planners and policymakers in Northwest Indiana with specific tools for making informed decisions on how best to allocate resources to improve the reliability of the freight transportation network. The I-65 Borman Corridor has a significant freight activity in the Midwest. This case study provides an opportunity to assess the economic impacts of operational disruptions of freight movements as measured by the travel time delay.
