Abstract:
This paper presents the
results of a full-scale crash test into an energy absorbing lighting
pole situated on an unlevel or sloped roadside. With poles representing
approximately one third of single vehicle accidents involving roadside
objects it is important to ascertain the performance of luminaire
supports in Australian road environment. Operational performance
of some pole types in unlevel road environments seriously diminishes
the safe and predictable performance of lighting poles. This research
utilises a full-scale crash test with an instrumented vehicle and
dummy to determine performance of the pole. Analysis of the data
acquired during the test was conducted to determine the performance
of the appurtenance and effect of an unlevel roadside on the test
outcome. The test results suggest that the test article is suitable
for use on Australian roadsides, particularly sloped roadsides,
pending some minor changes to the design. The study is limited to
one full-scale test due to the inherently high cost of full-scale
destructive testing. It is recommended that more testing of Australian
poles is conducted to allow the refinement of Australian appurtenances
making Australian roads more forgiving, reducing the number of lives
lost each year in Australia due to road crashes.
