ABSTRACT
The performance of the Minnesota Department of Transportation (MnDOT)P-1 28-inch parapet was
evaluated using trajectory simulation of both MASH car and pickup truck test vehicles. The MnDOT 28-inch P-1 parapet is considered structurally adequate by MnDOT engineers to resist passenger vehicle impacts.
This report concludes that the MnDOT 28-inch P1 parapet on 8-inch sidewalk can successfully
redirect both the MASH 1100C small car and 2270P pickup truck test vehicles at an impact speed of 35 mph and impact angle of 25 degrees. Other impact speeds and taller curb cases were investigated in this study but the lack of experimental data addressing tire/suspension model validity for higher speed and taller curbs does not facilitate a conclusion for these cases.
