| 摘要： | The City of Scottsdale, AZ, USA contains numerous examples of left-in left-out (LILO) median opening treatments at intersections and driveways where the minor leg is stop-controlled and the major road is free-flowing. These treatments are typically applied on arterial roadways with medians and consist of a channelizing island in the median which helps direct vehicles turning left both on to and out of minor roads or driveways. Additionally, the treatment contains a left-turn refuge with varying acceleration lengths for vehicles turning left out of minor roads/ driveways (these left-turning vehicles then merge with major road traffic). The City of Scottsdale began installing the LILO treatment several decades ago as a potential alternative to signalized intersections and it currently exists at approximately 60 locations. Although anecdotal evidence seems to indicate the LILO treatments in Scottsdale perform well with respect to operations and safety, a comprehensive analysis of this treatment had not been conducted. |
