In August 2013 the agency merged two routes along El Camino Real into the single all-day ECR route with 15-minute headways, briefly stemming a long-term decline in bus ridership that began in the early 1990s. Ridership on SamTrans buses was 52,140 passengers per weekday in November 2009; by November 2017, it had fallen to 37,830 bus passengers per weekday and continues to decline, further threatening the agency's budget. According to a route-level analysis, in 2014, four lines accounted for more than half of all weekday riders: ECR, 120, 292, and 122/28, with ECR alone accounting for more than of all weekday riders.
