Abstract

The objective of the study was to investigate the effect of two, four, and six-foot curbing on a bridge with ten-foot shoulders on the operational characteristics of vehicles on and in the vicinity of the bridge. The test results indicated a definite effect of curbing width on vehicle speeds and placements. The vehicle speeds with curbing in place were significantly lower than without curbing. There was a significant interaction between positions and conditions for vehicle placement.
