DYNAMIC TESTS OF BREAKAWAY LIGHTING STANDARDS USING SMALL AUTOMOBILES

Results of a study to determine the effectiveness of the current breakaway slip base lighting standards with long mast arms when impacted by small cars are reported. Results show that the current Type 31 slip base used in California is an effective breakaway device when impacted by small cars, and relatively high slip base bolt torques do not seriously affect the slip characteristics of the base. The changes in vehicle momentums measured in both tests were below the desirable maximum of 750 lb-sec (3335 N.s) specified in NCHRP Report 153. The deceleration data and apparent injuries to the dummy also indicate a relatively mild crash for both tests.
