ICT Research Identifies Data Inventory Collection Techniques for Implementation of Highway Safety Manual for IDOT

AASHTO’s Highway Safety Manual (HSM), published in 2010, presents a complete collection of quantitative safety analysis methods. It allows decision makers and engineers to evaluate safety alongside other transportation performance measures, such as traffic operations, environmental impacts, and construction costs. The Illinois Department of Transportation (IDOT) sought to expand the implementation of HSM methods to boost roadway safety in Illinois. However, the highway inventory data required for this implementation are not stored in IDOT’s databases. Therefore, a research project, funded by IDOT and conducted by the Illinois Center for Transportation (ICT), was instituted to identify and comparatively evaluate cost-effective techniques and methods for collecting and storing highway inventory data.
