Component

This research examined the major changes in a corridor due to high occupancy toll (HOT) lane implementation and the different impacts of those HOT lanes. Using three pairs of HOT lanes with similar design and operational characteristics, comparisons were made to examine the impacts of the similar HOT lanes in two different corridors. With strict registration requirements for free high occupancy vehicle (HOV)3+ travel on the I-95 Express lanes in Miami there were indications that some carpoolers switched to lower occupancy modes. Tolled access for HOV2s on I-95 and the SR-91 Express lanes near Los Angeles resulted in lower usage of those Express Lanes by the HOV2s as compared to most HOV lanes where HOV2 access is free. On the SR167 (Seattle) and I-25 (Denver) HOT lanes, exogenous factors like gas prices and the economic recession seemed to be the primary influence on the usage of those HOT lanes. In both cases, carpool usage was positively correlated to the gasoline prices. On I-25, the increasing unemployment rate coincided with a decrease in toll paying travelers. On SR 167 there were also indications of mode shifts among the transit, carpool and toll paying single occupancy vehicles (SOVs) due to fluctuating gas prices.
