Although curbs have been discouraged on high-speed roads based on previous research, the use of curbs is often required for certain situations. There exists a need to examine the use of curbs in conjunction with the Midwest Guardrail System (MGS) in order to determine effective curb placement guidelines. Four vehicle crash tests were performed to investigate vehicle behaviors after traversing a 152-mm (6-in.) AASHTO Type B curb. Two tests with 2270P pickup trucks, one test with the 1100C passenger car, and one test with the 2000P pickup truck, were performed. All of the vehicles were tested at a target speed of 100 km/h (62.1 mph) and at a target angle of 25 degrees. Test data was collected by both low- and high-speed video cameras and transducers. An analysis was performed on vehicle trajectories with respect to the MGS height to determine the critical lateral offset locations for further investigation within the curb-MGS combination study.
