| 摘要： | The high occupancy vehicle (HOV) lanes in the Salt Lake Valley operate between 600 North and 10600 South on Interstate 15 (I-15). They were opened on the reconstructed I-15 in May 2001. Two or more person carpools, vanpools, buses, motorcycles, alternative fuel vehicles (AFVs) and emergency vehicles are eligible to use the HOV lanes. They operate in both the northbound and southbound directions and are separated by a solid white striping that allows HOV entrance and exit. They operate 24 hours a day, seven days a week. There are inside ramps to the HOV lanes at 400 South, which is the downtown area in Salt Lake City. A previous study of the HOV lanes was conducted before the lanes opened and continued through their first year of operation. The study recorded several HOV lane benefits. This report is based on an exhaustive evaluation of the third year of HOV lane operation in the Salt Lake Valley. The measures of effectiveness adopted were vehicle volume, average vehicle occupancy (AVO), modal split, person throughput, travel time, speed, accident rates and violation rates. Vehicle volumes and speeds were collected by video detection using the video feeds provided by the Utah Department of Transportation. |
