Abstract:This report presents the Environmental Data Test Plan for the national evaluation of the Los Angeles
(LA) Congestion Reduction Demonstration (Metro ExpressLanes) under the United States Department
of Transportation (U.S. DOT) Congestion Reduction Demonstration (CRD) Program. The Los Angeles
CRD projects focus on reducing traffic congestion by employing strategies consisting of combinations
of tolling, transit, telecommuting/travel demand management (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 LA 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 bus service connection, and the expansion of downtown
LA transit signal priority. TDM strategies aim to establish 100 new registered vanpools. This
Environmental Data Test Plan is one of ten test plans being developed. The other nine test plans consist
of the following: traffic; exogenous factors; transit systems; surveys, interviews and workshops;
ridesharing; safety; tolling; content analysis; and cost-benefit. Each test plan is based on the LA CRD
National Evaluation Plan. This test plan describes the sources, availability, and possible risks associated
with the data. The methods for analyzing the tolling data are discussed. The schedule and responsibility
for collecting, analyzing, and reporting the environmental data are also presented.
