This paper examines the optimal lane width of the urban expressway by using a driving simulator. Vehicle speed and lateral offset were selected as indicators of driving safety, and limited speed and free speed experiments were carried out. The results show that lane width has a significant effect on lateral offset but not on vehicle speed. According to the lateral offset, when the speed limit is 80 km/h, the reasonable lane width is preferably greater than or equal to 3.25 m. When the speed limit is 100 km/h, the reasonable lane width is preferably greater than or equal to 3.5 m. According to the in-lane driving proportion, 3.25 m can meet the requirements of normal driving. In order to satisfy driving safety, the lane width can be compressed to improve the user efficiency of the urban expressway.
