Abstract:
The Louisiana Department of Transportation and Development (LDOTD) contracted with the Texas Transportation Institute (TTI) to evaluate the impact characteristics of Louisiana's multi-directional, 8.9 cm (3-1/2 in) diameter steel post, small sigh support when impacted by an 820 kg (1,808 lb) vehicle at 35 km (22 mi/h) and 100 km/h (62 mi/h). The full-scale crash tests were conducted and evaluated in accordance with the criteria provided in the 1985 American Association of State Highway and Transportation Officials (AASHTO) Guide: Standards Specifications for Structural Supports for Highway Signs, Luminaries, and Traffic Signals and the National Cooperative Highway Research Program (NCHRP) Draft Report 350. Both the low and high-speed impact tests satisfied the test criteria by: (1) the sign support yielding to the vehicle, (2)the sign installation and vehicle presented no undue hazard to other motorist after impact and (3) occupant risk values were well below the maximum allowable levels. This sign installation in "standard soil" is acceptable according to the test level 3 evaluation criteria recommended in NCHRP Report 350 and the 1985 AASHTO Standards.
