This report describes a series of full-scale vehicular crash tests conducted to evaluate the impact performance of small sign supports used by the Arizona Department of Transportation (ADOT). The tests were conducted and evaluated in accordance with the recommendations of NCHRP Report 230 and the 1985 AASHTO "Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals."

Guidelines were developed to assist the Arizona Department of Transportation (ADOT) in (1) determining if an existing sign installation, not in compliance with current safety standards, should be replaced by a system that does meet the safety standards, and (2) selecting a cost effective sign support for new installations. A benefit/cost (B/C) program, developed at the Texas Transportation Institute (TTI) was used to develop the guidelines.

Guidelines are presented to assist transportation agencies select a sign support system. Three major elements are addressed in the guidelines: safety, design, and economics. An economic analysis procedure was formulated whereby the present worth of initial and annual costs of a given support system can be computed and compared with costs of other systems. The procedure was used in an example to analyze the relative costs of available support systems for small sign installations. A limited sensitivity analysis was also performed to evaluate the influence of input parameters on costs.

Summarized are the results of a study entitled "Cost Effectiveness of Small Highway Sign Supports." The basic purpose of the study was to develop objective criteria and methodologies to assist the engineer in the selection of a cost-effective sign support system. To accomplish this objective, four tasks were required. These were (1) survey existing practices, (2) evaluate the crashworthiness of widely used support systems and promising new systems, (3) develop methodologies whereby candidate systems could be evaluated on a cost-effective basis, and (4) to the extent possible, identify the relative cost-effectiveness of current systems.
