In 2004, CAT received its first shipment of 10 bus rapid transit (BRT) vehicles from Irisbus. These buses served on the new Metropolitan Area Express (MAX) route, which serves Nellis Air Force Base via North Las Vegas Boulevard. RTC was a member of the BRT Consortium organized by the Federal Transit Administration (FTA) in 1999. North Las Vegas Boulevard had been restriped in spring 2000, which converted what had been a breakdown lane into a dedicated transit lane; RTC subsequently applied for a federal grant in 2002 under the Bus Rapid Transit Initiative. The Civis featured an optical guidance system (OGS) to automate docking at level-boarding platforms, similar to a light-rail system; however, the OGS proved to be unreliable in service due to the difficulty of maintaining pavement markings. Revenue service on MAX started on June 30, 2004; ridership increased by 25% by the end of 2004, and end-to-end travel times were cut approximately in half, from 50 to 25 minutes.
