In 2010, SPAD introduced the express transit system in Klang Valley, namely BET, where the buses utilize less congested highways to link between heavily populated areas and city centers in Kuala Lumpur, Putrajaya and Penang. Naturally, by using the highways, travel time is reduced as the highways are less congested than the normal routes. The service will have limited stops and rely on feeder buses and park-n-ride facilities to ensure sufficient ridership. With BET, travel time is expected to be reduced by up to 50 percent on certain BETs.
