Intersections and Mid-Block Crossings
Wider or offset intersections are particularly good candidates for intersection markings. They can reinforce the proper path for bikes and instill confidence in crossing larger intersections. Typical markings include dotted lines through the intersection with a width and position consistent with the bike facility it follows. Shared lane markings and colored pavement can be used to further highlight the bike treatments. Colored pavement can be especially useful at conflict points both through intersections and at conflict points with driveways. BIKE PROTECTED INTERSECTIONS Protected intersections have been implemented across North America as cities have expanded their protected bikeway networks. Also known as setback or offset intersections, this design keeps bicycles physically separate from motor vehicles up until the intersection, providing a high degree of comfort and safety for people of all ages and abilities. This design can reduce the likelihood of highspeed vehicle turns, improve sightlines, and dramatically reduce the distance and time during which people on bikes are exposed to conflicts. For example, in San Francisco, a protected intersection design resulted in 98% of drivers yielding to people on bikes, and 100% yielding to people walking. A study in New York found that protected intersections had fewer vehicle-bike conflicts than even a dedicated turn lane with a dedicated bike signal phase 37 .
Transit Intersection Treatments Transit-specific intersection treatments can elevate transit to an equal standing with other modes on Hillsborough County’s streets by creating an environment supportive of reliable and efficient service. The following treatments are summarized to provide an overview of treatments available. Further guidance on the use of these treatments is available in the NACTO Transit Street Design Guide. RIGHT-TURN LANES The interaction of Bus Only Lanes and right-turn lanes can provide priority for buses through an intersection. For moderate right-turn volumes, turning vehicles can share a bus lane
