Impacts to Transit from Los Angeles Congestion Reduction Demonstration

The Metro Los Angeles Congestion Reduction Demonstration (CRD) converted the carpool lanes on I-110 and I-10 into dynamically priced managed lanes. A significant share of the CRD funds was used to improve the Metro Silver Line express bus on I-110 and the Foothill Transit Silver Streak express bus on I-10. The purpose of this research paper is to highlight some of the transit evaluation findings. In the I-110 corridor, ridership on the Silver Line increased 52 percent in the morning peak period and 41 percent in the afternoon peak period. After tolling began, ridership increased another 29 percent in the morning peak period and another 25 percent in the afternoon peak period. In the I-10 corridor, service was added to the Silver Streak concurrent with tolling. Ridership increased 59 percent in the morning peak period and 15 percent in the afternoon peak period. The data suggests that implementing variable tolls has had little or no negative impact to bus travel times. On I-110, the Silver Line’s average travel time after tolls increased less than a minute in the morning and was virtually the same in the afternoon. On I-10, the Silver Line’s average travel time decreased 4 percent in the morning and 14 percent in the afternoon. That 14 percent reduction equated to a 2.6 minute reduction. The Silver Streak’s average travel time on I-110 decreased 22 percent in the morning and 17 percent in the afternoon. This amounted to a 4.7 minute and 3.8 minute reduction respectively
