Sign design, content, placement standards, measures to avoid visual clutter, installationand maintenance polices, and other considerations need to be established and agreedupon by stakeholders and responsible parties prior to implementation. The partiesresponsible for installation and maintenance need to be apprised of protocols includingcoordination of responsibilities when multiple agencies are involved. This needs toinclude entities with roadway construction authority so that roadway projects impactingtrail crossings and intersections include appropriate and uniform design treatments andstandards, regardless of locality. As development and implementation of IntelligentTransportation Systems occurs wayfinding resources could be added such as locationspecificinformation via cell phone (based upon mile posts along bicycle routes and railtrails).Project 5.2.3: Intersection Improvements on Setucket Road PathProject Description – Intersection treatments along the Setucket Road and OldChatham Road Paths are inconsistent and lacking in conspicuous pavement markingsthat comply with national standards and design guidelines. Designed primarily as a sidepath, there is a resultant 38 roadway crossings in only 7 miles, and as a result a need forhigh visibility crosswalks and other pavement markings to communicate to motoristsand path users the presence of conflict points. Pavement markings and signage alsocommunicate appropriate actions at intersections for both motorists and path users.Additionally, access to the paths needs to be upgraded to provide curb ramps and ADAcompliantdetectable warning surfaces.Preliminary Design Concepts – High visibility crosswalks and improved signage andintersection treatments that are consistent with MUTCD and ADA standards andAASHTO design guidelines need to be selected to be applied uniformly along the facility.Consideration should also be given to evaluating the existing configuration andgeometrics for each of the intersections and changes made that will enhance safety. Thisreview should include issues such as sight distance, bollard placement, path width, angleof approach/crossing (skewed crossings), etc.Cost Estimate – Costs vary subject to existing conditions and improvements needed atindividual locations. Unit costs for typical crossing improvements are provided.• Residential Crossing – $1,500.00• Signalized Crossing – $70,000.00Assumes installation of signalized intersection on two-lane roadway with mast arms,signal heads, pedestrian signals, pavement markings, and appropriate pedestrianupgrades such as curb cuts and ADA curb ramps.Recommendations for Implementation – A complete review of the existingconditions should be conducted and documented and feedback from users should becollected to identify deficient conditions and desired improvements. Existing elementsthat are not consistent with MUTCD standards, AASHTO guidelines, and current bestChapter 5: Bike & Pedestrian Cape Cod Regional Transportation Plan | August 2011Page 402
