by COTA's new lift-equipped buses. From 2007 to 2008, the agency removed all exterior advertisements from its buses, citing diminishing ad revenue and desiring a clean, neat look to the buses. The agency purchased its downtown office, the William J. Lhota Building, in 2008. Also in 2008, the city of Dublin was added into COTA service areas. In 2016, COTA introduced 4G connectivity in its buses, giving passengers better internet access and allowing for real-time bus tracking to improve communication and efficiency. Real-time bus tracking for passengers began in May 2016 through the Transit app. On May 1, 2017, the agency overhauled its bus network, the first redesign since COTA's establishment in 1971. The effort simplified routes, increased bus frequency, connected more locations, and reduced bus congestion in downtown Columbus. The redesign doubled the agency's number of frequent lines (from four to eight) and significantly increased weekend service. The project caused a 3.6 percent increase in ridership by May 2018. In August 2017, COTA became the third large transit agency with fleet-wide passenger WiFi. On June 1, 2018, COTA began the C-Pass program, giving employees of certain companies downtown free rides on COTA buses. By 2019, the program enrolled about 420 companies. C-Pass is scheduled to be discontinued on December 31, 2020; property owners will decide whether to fund the program further. In July 2019, the agency's customer service center at its headquarters closed for renovations. The project involved creating a larger, more inviting space, installing new ticket machines and a large display with transit information, and redesigning part of the building's exterior. The agency opened the new Customer Experience Center in November 2019. In the first "tactical urbanism" project COTA and the City of Columbus operated a temporary busway on Third Street in downtown Columbus from July 22 to August 2, 2019 in an area heavily congested during rush hour. The results were significantly decreased travel times, the average dropping over two minutes from Long Street to Noble Street. The project was inspired by the city of Boston converting a bike lane and on-street parking into a temporary busway. Also in 2019, COTA introduced the COTA Connector system for fare payments. The system includes a smart card that is available for purchase and refills, and a digital wallet through a smartphone app, allowing the use of displayed QR codes to pay when boarding buses. In 2020, COTA reported 19.1
