Every sector of urban transportation faces the problems of rising costs, limited funds, and depleting resources with which to provide for increasing travel demands. Getting the greatest production out of the existing transportation facilities is the goal of every transportation agency. The Texas State Department of Highways and Public Transportation is testing the concept of increasing roadway capacity on urban freeways by restriping the mainlane pavement with narrower lane widths and encroaching on the shoulder to create one additional lane for travel. Two sections of U.S. 59 southwest Freeway in Houston were modified for study. Before and after data were collected over a seven-year period to determine the effectiveness of reconfiguring the surface geometrics of freeways to provide an additional lane for travel 24 hours every day. A second section was modified to provide the additional lane during peak periods only on weekdays. This 'permissive' design was studied over a four-year period.
