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. Additional tasks dealt with the impact behavior of rural mailboxes, crash test evaluation of selected small sign supports using subcompact automobiles, and static load tests of a signpost in soil. Results of the study are presented in seven technical reports. A narrated, documentary 16mm movie presenting a summary of the study was also developed.
