  • Abstract:
    The primary objectives of this research included an identification of literature in Utah and nationally on ; how changing toll rates, occupancies, and violation rates have had an effect on Express Lane use and an examination ; of the utilization of the Express Lanes under a limited number of congestion and pricing scenarios. The results of ; this study indicate that while the majority of the Express Lane corridor within the state of Utah is operating within ; acceptable ranges set by the Utah Department of Transportation (UDOT) and Federal Highway Administration ; (FHWA), there are several zones where 10th ; percentile speeds have dropped below the 55 mph goal set by UDOT ; including Zones 140 and 145 in the AM peak and Zones 145, 250, and 260 in the PM peak. Additionally, the 10th ; percentile speeds in Zone 255 in the PM peak have dropped below the FHWA requirement of 45 mph. ; There are several methods to reduce the volume in the Express Lanes, which, if implemented, are ; anticipated to increase the speeds within these lanes. These methods include: 1) increase Express Lane tolls during ; peak periods; 2) increase the High Occupancy Vehicle (HOV) limits in the Express Lanes; 3) reduce violation rates ; along the corridor through methods such as improved enforcement, education, campaigns, etc. and 4) enforce ; current cap for “C” decal vehicles in the Express Lanes and consider options for increasing the number of “C” ; decals issued for off-peak travel and/or travel outside of the congested areas during peak periods. ; To better understand the impacts of the alternatives additional research is necessary including a detailed ; analysis of average vehicle occupancy (AVO) in the Express Lanes and the GP lanes and a more detailed analysis of ; enforcement alternatives for the state. Additional research could also include a survey of travelers to better estimate ; their toll price elasticity, and a detailed analysis of the geometry of the Express Lane corridor.
