Performance Implications Of Bicycle Specific Treatments At Signalized Intersections, Andrew Kading Apr 2016

Performance Implications Of Bicycle Specific Treatments At Signalized Intersections, Andrew Kading

Civil and Environmental Engineering Master's Project Reports

A rise in cycling nationwide has brought an increased awareness of bicycle specific safety concerns, particularly right-hook crashes at signalized intersections. There are several common and emerging signal timing strategies that are can be used to improve the safety and efficiency of traffic signals for people on bicycles, including the Leading Bicycle Intervals (LBI), Split LBI, and Exclusive Bicycle Phasing (EBP). The leading and split bicycle intervals provide a head start for bicycles in advance of concurrent and conflicting motor vehicle movements, typically about 3-5 seconds. The EBP provides an interval only when bicycles are moving. To examine the performance …
