Light rail ridership is tabulated using Federal Transit Administration-approved automatic passenger counters (APCs) as its official methodology. Results of a year of testing showed the APCs to be far more accurate than manual counting, and that DART had been underreporting ridership by approximately 15.5 percent by using the manual counting methodology.
The decrease in high-occupancy vehicle (HOV) lane ridership correlates to certain lanes being taken out of service because of construction. The HOV lane on I-635 between I-35E and U-75/Central Expressway was taken out of service in summer 2011. The lane on I-30W will be taken out of service in 2014. The I-35/US-67 HOV lanes also will be impacted by construction. Effective Oct. 1, 2013, the Texas Department of Transportation assumed maintenance, enforcement, and operational responsibility for the HOV lanes within the DART Service Area. DART will continue to report revenue miles from DART's operation of buses on the HOV lanes and receive the associated FTA formula funds.
