Metro Rapid is a local express bus service with bus rapid transit (BRT) characteristics in Los Angeles County, California. At its peak, Metro had dozens of Rapid routes, but , the system has been largely discontinued. Just three Metro operated Rapid routes remain, along with four routes operated by Big Blue Bus, one by Culver CityBus and one by Torrance Transit. To reduce travel times, buses are equipped with a special transmitter that send a signal to traffic lights, which cause them to favor the bus by holding green lights longer and shortening red lights. Metro Rapid buses also stop less frequently than other routes, with Rapid stops located only at major intersections and transfer points. The frequency of Metro Rapid buses is increased as well, as more buses on a line translates to less wait time at each station. All Metro Rapid buses are low-floor CNG buses for faster boarding and alighting and distinguished by their prominent red color. Overview The Metro Rapid Program was implemented in June 2000-December 2002 with the goal of improving bus speeds within urbanized Los Angeles County. Lines 720 (Wilshire), 745 (Broadway), 754 (Vermont), and 750 (Ventura) were the pilot routes of the program. Metro claims travel times were reduced by as much as 29%. Metro Rapid buses are distinguished by their red and silver livery. Some Rapid stops are equipped with "NextBus" technology which indicates the wait time before the next bus arrives. NextBus displays were installed mostly at stops on Lines 720 and 750. Metro Rapid Lines 720, 744, 770, and 780 were the only lines that complemented multiple lines (the 720 ran alongside the 18 and 20; the 744 ran alongside 233 and 240; the 770 ran alongside 68 and 70; and the 780 rans alongside the 180, 181 and 217); Line 720 is the longest route in the Metro Rapid system. It takes roughly 2 hours from start to end during rush hours. Also, line 720 is the most frequent of all Rapids. In the morning rush hour, the Rapid 720 ranges from every 2–10 minutes. As of June 27, 2021, most lines that complemented multiple lines, except Lines 720 and 754, were discontinued as a result of Metro’s NextGen Bus Plan by merging the Rapid Lines with their Local counterparts to create higher frequency. Line 720 was truncated to Downtown LA at 6th/Central meaning it will no longer complement
