2010 Crash Facts Book
The Alabama Crash Facts Book (CFB) is an annual publication produced in part by CAPS that provides a wide breadth of traffic safety statistics for a variety of constituencies. While most of the users of the CFB are traffic safety personnel, this publication is also intended to serve as a public information conduit.
Work Zone Lane Closure Analysis Model
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).

Crash Cost Estimates by Maximum Police-Reported Injury Severity Within Selected Crash Geometries
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 […]

FHWA Crash Cost Estimates by Roadway Type and Speed Limits
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 severity scale […]
Highway Safety Information System: An Examination of Fault, Unsafe Driving Acts, and Total Harm in Car-Truck Collisions
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.

National Work Zone Safety Information Clearinghouse
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 […]
