    About this Project
    Brief Project Description & Background
    This project involves two major steps for applying the national Highway Safety Manual (HSM) in states. The first step is the calibration of HSM to local conditions using historical safety, geometric and demand data. The focus of the calibration will be on Missouri although other MATC states could also benefit from the results. The second step is the development of training and technology transfer for a wide range of organizations including MoDOT, metropolitan planning organizations, regional planning commissions and local communities.
    Research Objective
    The objective is to develop a long term process for calibration of HSM and not just produce a set of calibration values once. The calibration process will be carefully documented so that future calibrations can follow the same procedures using the same types of data.
    Potential Benefits
    The first major product is the documentation of the overall calibration process that will be formatted for inclusion into the DOT policy guides. This will allow the on-going updating of HSM calibration factors in the future. The second product is a set of calibration factor tables. The tables will be in a user-friendly "wiki" format that could easily be translated into other document formats for other MATC states.
