Bridge Health-Informed Route Planning: Challenges and Promises

Bridge Health-Informed Route Planning: Challenges and Promises

Bridge safety in transportation and logistics is a pressing issue for many countries, and the United States is no exception. In fact, the ACSE gave an overall cumulative grade of C- for the US infrastructure. The presence of unsafe bridges within transportation routes poses significant challenges to many stakeholders. This includes traffic safety concerns, environmental hazards, and economic implications, as exemplified by the Yellowstone River, Montana, and Minneapolis 35W bridges.

This paper proposes integrating bridge health information in route planning. Our research encourages stakeholders to make informed decisions by taking into account bridge risk factors and the sensitivity of transported materials (e.g., hazardous materials, heavy equipment etc.). This approach enables strategies like load balancing, rerouting enforcement, and prioritizing maintenance tasks to be applied effectively.

First, we discuss our methodology of generating a bridge-health enhanced Geographic Information System (GIS) dataset that integrates bridge information from the National Bridge Inventory (NBI) with GIS data from OpenStreetMap. Leveraging this dataset, we analyze example origin-destination (OD) pairs in Nebraska to demonstrate how different routes in Nebraska exhibit, besides differences in travel distance, varying statistics on bridge health scores. We also introduce a simulation platform for route planning and visualization currently being developed.

We finally discuss the challenges we faced and opportunities ahead in merging these distinct datasets (GIS and NBI). The platform, coupled with the enhanced GIS dataset, offers valuable tools for transportation engineers, researchers, policymakers, and route planners alike.

Furthermore, our findings and proposed methodologies provide valuable insights for optimizing transportation safety, reducing environmental impact, and efficiently maintaining infrastructure. We conclude that incorporating bridge health considerations into route planning can improve safety, efficiency, and sustainability of transportation networks.
