Abstract:Problem: The first version of the Highway Safety Manual (HSM) was released in 2010 and is currently being deployed by several states as the primary methodology for performing predictive analysis to identify critical segments of the network and to evaluate the benefits of countermeasures. In this context, it is critical to train the current and future professionals on the underlying theory behind these methods and the effective application of the same. Although the HSM methods rely on vast amounts of spatial data (roadway network and geometry, geo-coded crashes etc.) the training materials rely mostly on spreadsheet-based tools for application of the methods and the HSM software are also non-spatial and do not directly integrate with Geographic Information Systems (GIS).
