    About this Project
    Brief Project Description & Background
    The Missouri HAL manual is used for identifying, analyzing and correcting high crash locations and has not been updated since 1999. There is an urgent need to bring this manual up-to-date and to incorporate the methodology that is included in the national Highway Safety Manual. This fourth edition is expected to be a complete re-working of all existing chapters of the manual and the addition of new statistical methodologies such as Empirical Bayes, Negative Binomial models, Safety Performance Functions (SPFs), Crash Modification Factors (CMFs) and Calibration factors (Cs).
    Research Objective
    The objective is the publication of an improved HAL manual that will be user-friendly to local communities.
    Potential Benefits
    One potential benefit is the improvement in safety of local communities who can utilize the updated HAL manual for establishing and operating local safety programs.
