Safety Issue #6. Pedestrian AccommodationsEnhancements:1. With intersection improvement to a roundabout or traffic signal, include appropriatepedestrian accommodations. If the intersection remains unsignalized, consider installingcrosswalks at the intersection with appropriate advance warning signage.Safety Issue #7. Bicycle AccommodationsEnhancements:1. Redesign of the intersection should incorporate bicycle accommodations such as a 4-foot paved shoulder, bike route signing, and bicycle detection if a signal is installed.Safety Issue #8. SpeedEnhancements:1. Conduct a speed study to determine the prevailing speeds and adjust speed regulationas necessary based on findings.2. Increase enforcement in the vicinity of the intersection through the use of either speedtrailers or uniformed officers.3. Reconfiguration of the intersection into a 5-leg roundabout will reduce speeds throughthe intersection area.3.4.2 DENNIS ROADWAY SAFETY AUDIT3.4.2.1 Route 134 at the Route 6 RampsThis study completed in 2009 identified six safety issues and associated enhancements:Safety Issue #1. Interchange GeometryEnhancements:1. Review operations and the feasibility of adding adequate acceleration and decelerationlanes at the interchange of Route 134/Route 6.2. At the Route 6 eastbound off-ramp to Route 134 southbound, lengthen the solid whitechannelization line from the end of the delta island to reinforce the separation betweenthe ramp and Route 134 southbound, and to delineate the additional lane. Replace themerge sign with an “add lane” warning sign. In conjunction, review the distancebetween the Route 6 eastbound ramps and the mall signal for appropriate weavedistance.3. Provide adequate turning radii to accommodate larger vehicles in a single lane on theRoute 6 eastbound ramp to Route 134 southbound and on the Route 6 westbound rampto Route 134 northbound.Chapter 3: Safety Cape Cod Regional Transportation Plan | August 2011Page 302
