Abstract:This document presents the final report on the national evaluation of the Los Angeles Congestion Reduction Demonstration (LA
CRD) ExpressLanes Program under the United States Department of Transportation (U.S. DOT) CRD Program. The LA CRD
projects focus on reducing congestion by employing strategies consisting of combinations of Tolling, Transit, Telecommuting/TDM,
and Technology, also known as the 4Ts. Tolling (pricing) strategies include converting high occupancy vehicle (HOV) lanes on the
two freeway corridors to variably-priced high-occupancy toll (HOT) lanes, adding a second HOT lane to portions of one corridor,
and implementation of a downtown L.A. intelligent parking management system featuring demand-based pricing and real-time
parking availability information. Transit improvements include increased bus service, transit station security improvements,
expansion of two transit stations, creation of an El Monte Busway/Union Station connector, and the expansion of downtown L.A.
transit signal priority. TDM strategies aim to establish 100 new registered vanpools. The national evaluation of the LA CRD
projects was guided by the National Evaluation Framework, the LA CRD National Evaluation Plan, and individual test plans for
various components. This report provides information on the use of the new LA CRD projects. Changes in travel speeds, travel
times, trip-time reliability, and transit ridership are described. The air quality, energy, and safety impacts of the LA CRD projects
are examined. Information on changes in unemployment rates and gasoline prices is also summarized.
