At the Alabama Department of Transportation (ALDOT), the tool used by traffic engineers to predict whether a queue will form at a freeway work zone is the Excel-based ―Lane Rental Model‖ developed at the Oklahoma Department of Transportation (OkDOT) and whose work zone capacity values are based on the 1994 Highway Capacity Manual (HCM, 1994).

Publication No. FHWA-HRT-05-051 This paper presents estimates for the economic (human capital) and comprehensive costs per crash for six KABCO groupings within 22 selected crash types and within two-speed limit categories (= 50 mi/h)). The comprehensive costs include nonmonetary losses. To produce these cost estimates, previously developed costs per victim keyed on the AIS injury […]

The Federal Motor Carrier Safety Administration (FMCSA) has given high priority to research regarding collisions between large trucks (gross vehicle weight > 4,540 kilograms (10,000 pounds)) and other vehicles on the roadway. This research aims to improve knowledge about the high-risk behaviors of truck and passenger vehicle (car) drivers.

The issue of work zone safety cannot be properly addressed without attempting to understand fully the problems associated with work zones. The purpose of this research project was to investigate the current status of work zone safety in Alabama and other states and to recommend possible safety-enhancement measures. A database of crash report information was […]
This manual describes a comprehensive approach to traffic safety analysis, from collecting potentially useful information to ranking tentative solutions. Individual chapters can also be consulted and applied independently, such as to check a location’s crash ranking (Chapter 3), alternative crash countermeasures (Chapter 4) or the relative safety benefits and costs of a specific countermeasure (Chapter […]
Report No.: ANSI D16.1-1996 The primary purpose of the Manual on Classification of Motor Vehicle Traffic Accidents is to promote uniformity and comparability of motor vehicle traffic accident statistics now being developed in states and local jurisdictions.
