    • Reducing Speeds in our Rural Communities and Increasing Safety Neil E. Boudreau MassDOT State Traffic Engineer January 18, 20131 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • MUTCD Speed Zoning Criteria Standard – Requires Engineering study Post only in 5 MPH multiples Guidance – Within 5 mph of 85 percentile Re-evaluate every 5 years Optional Factors – Road characteristics Roadside development Parking and pedestrian activity Crash experience (min. 12-months)2 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • State Guidelines MGL Chapter 90, Sections 17 & 18 define speed limit control in MA MassDOT’s Speed Zoning Procedures helps municipalities understand the process Regulatory – Requires an engineering study to determine 85th% speed and guide the setting of the “posted” limit Statutory - maximum speed limit applicable to a particular type of roadway characteristics (i.e. Thickly Settled, Business District)3 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Functional ClassificationCategorization of roadways by the character of service they provide Service characteristics Access Mobility Roadway connectivity Adjacent land use Topography Road Function defines speeds4 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Rural Road Challenges Higher speed roadways passing through Town Centers or near schools with different roadside environments Higher speed roadways that also share the road with farm equipment, bicycles and pedestrians Lack of pedestrian and bicycle facilities Frequent horizontal and vertical curvatures in the roadway – poor sight distance Lighting and visibility – few rural roadways are lit making it particularly hard to see other road users at night5 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Engineering Measures for Managing Speed Context Sensitive Design – Urban Areas Traffic Calming Roundabouts Perceptual measures Vehicle activated speed displays Roadway design elements6 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Contact Sensitive DesignContext Sensitive Solutions is acollaborative, interdisciplinary approachthat involves all stakeholders to develop atransportation facility that fits its physicalsetting and preserves scenic, aesthetic,historic, and environmental resources,while maintaining safety and mobility.7 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Traffic Calming8 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Roundabouts9 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Perceptual Measures10 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Vehicle Activated Speed Displays11 | Leading the Nation in Transportation Excellence | www.mass.gov/massdot January 30, 2013
    • Roadway Design ElementsGateway treatments and roadside plantings Help inform the driver of a changing environment Help define town centers and other areas (e.g. schools, recreational parks) Help with speed reductions and can also help narrow the roadwayRoadway Cross Section/Road Diet Narrow lane widths Inclusion of bike lanes and/or parking Sidewalks offset by grass strip
