The driveway width determines the layout of roadway cross-section and land resources allocation, affecting the running speed, roadway capacity and safety level. Using the calibrating and statistical methods, an investigation of the running speed on seven different widths (3.2∼4.0m) of urban driveways was conducted and a function of both running speed and speed variance with driveway width was analyzed. The analysis shows that there are no pertinence between the driveway width and speed variance, and no linear dependence with speed within the range of 3.2∼3.5m. A reasonable range of urban driveway width was proposed, and a comparison between the results with the criterions in other countries was given.
