Florida uses restrictive medians and directional median openings to manage left turns and crossing movements on multilane highways. Left turn egress movements from driveways or side streets would be replaced by turning right onto the major road and then making U-turns at downstream median openings or signalized intersections. One of the public concerns regarding this treatment is that drivers making a right-turn followed by a U-turn (RTUT) could experience much longer delay and travel time than those who would otherwise make a direct left turn (DLT). This study analyzed the operational effects of a widely used access management treatment: U-turns at downstream signalized intersections as an alternative to direct left turns. Data were collected on eight selected street segments in the Tampa Bay area in Florida. A total of more than 300 hours of traffic data were collected.
