Urban arterial streets are designed to provide for through traffic movement and some land access, but they are often called upon to store vehicles by providing curb parking spaces. This study was initiated to determine the frictional effect on through movement caused by vehicles maneuvering into and out these curb spaces. The digital computer simulation method was used following an extensive literature study and limited data collection. The computer model simulated a two-lane, tow-way, 660-ft. Long urban arterial street block containing 20 paralel curb parking spaces. The model was programmed in fortran for the ibm 7094 computer using a modified physical representation method of simulation with periodic scanning. The experimental design tested three levels of service and seven parking turnover rates. The results of statistical tests on the data indicated that level of service was more influential in determining the amount of delay to through vehicles than parking turnover rate.
