This project was concerned with the transition designs used between w-beam and the guardrail, and rigid bridge rail parapets or wingwalls. State designs submitted to the federal highway administration (FHWA) were rated and designs selected for crash test evaluation. New designs were also formulated and subjected to crash test evaluation. Most of th

This is the fifth report to Congress under Section 207. The reports contain an extension of a series of statistical data published annually since 1967 by the Federal Highway Administration (FHWA) as "Fatal and Injury Accident Rates on Federal-Aid and Other Highway Systems." The series has been a cooperative effort of the FHWA1s Offices of Traffic O

This report is the users manual for the SRAP (Safety Resource Allocation Programs) microcomputer program package on IBM-PC and compatible microcomputers. The SRAP package contains three computerized methodologies-incremental benefit-cost analysis, integer programming, and dynamic programming-developed by the FHWA to aid highway safety planning deci

Users of this manual are expected to be researchers who are attempting to develop models that can be used to predict occurrence of pedestrian accidents in a particular city. The manual presents guidelines in the development of such· models. A group-type analysis approach for the prediction of pedestrian/vehicle accidents using pedestrian/vehicle co

Users of the manual are expected to be in divisions responsible for pedestrian safety in cities, counties, and other jurisdictions. The users manual outlines a step-by-step procedure to measure pedestrian volumes using small count intervals. Appendixes are given to present and discuss the methodology of this procedure. the MUTCD Warrant 3 minimum p

We report the development of a premixed electrically conductive polymer concrete overlay for use on bridge decks and other concrete members, in conjunction with cathodic protection systems. The development of a conductive overlay culminated in the installation of such an overlay on a full-bridge deck in Pulaski, Virginia; the active cathodic protec

Safety Steps for Pedestrians; Effects of Calcium Magnesium Acetate on Reinforced Steel Concrete; Prediction of the Service Life of Warning Signs; Analysis of Concrete Cores from a Cathodically Protected Bridge Deck
The report documents the development and installation of an instrumented pavement on I-80 in Iowa for the purposes of demonstration and answering current pavement questions. Its two primary objectives include documentation of the installation and verification of existing design procedures through monitoring of the continuous traffic stream reaction

Accident surveillance programs require a measure of wet-pavement exposure to determine whether the wet-pavement accident rates of particular highway sections are higher or lower than expected. This research program used the results of laboratory and field tests, together with available weather data to construct a model for estimating the percentage

A study was made of the influence of consolidation on properties of portland cement concrete. Consolidation was found to have a strong influence on compressive strength, bond of concrete to reinforcing steel, and permeability of concrete. There is a lesser effect of consolidation on resistance to freezing and thawing. There is a loss of about 30 pe
