EVALUATION OF HOV AND SHOULDER TRAVEL LANE STRATEGY FOR I-95

In December 1991, the Virginia Department of Transportation (VDOT) adopted 24-hour shoulder lane travel on Interstate 95 (I-95) through heavily congested Northern Virginia, outside of Washington, D.C. This interim strategy was designed to work in conjunction with existing high-occupancy vehicle (HOV) lanes to relieve congestion until construction activities could be completed. Public concern about the effectiveness of the strategy and the potential safety impacts prompted VDOT to initiate a system analysis of the corridor's traffic operations. This study focuses on a 12.4-km (7.7-mi) section of eight-lane divided freeway on I-95. The purpose of this study was to assess the impact of the HOV/shoulder lane travel strategy on traffic operations and safety, to identify actual and potential problems, and to suggest measures for remediation. The findings of the study are explained and details provided on the three types of analyses conducted--forecasting, statistical, and capacity and simulation.
