IN-HOUSE ACCESSIBILITY TREATMENTS Universal Design for Plazas, Bikeways and Shared Streets NACTO Designing Cities 2017: Chicago Background 1 nyc.gov/dot STREET IMPROVEMENT PROJECTS Before Goals: • Safety • Accessibility • Mobility for all users • Enhanced quality of life After SIP Allen-Pike Streets, Chinatown, Manhattan 100+ quick, in-house pedestrian, bike, & bus projects a year, small to large 3 nyc.gov/dot TEMPORARY SIDEWALK EXTENSIONS Flexible delineators Granite blocks “Truffle” colored paint or epoxied Planters with aggregate maintenance partner Division St, Chinatown, Manhattan Litter & snow removal required by maintenance partner or streetsweepers/snowplows Union Square, Manhattan 4 nyc.gov/dot ACCESSIBILITY OUTREACH • NYC DOT approached by People for Accessible & Safe Streets, an advocacy group for low vision & blind pedestrians • In-house painted/epoxied gravel spaces flush with roadway not detectable by cane users who usually rely on curb edge or detectable warning in pedestrian ramps • In 2013, NYC DOT hired a consultant to develop accessibility treatment standards • Five main design goals were developed to delineate the edge of the temporary spaces Madison Square, Manhattan 5 nyc.gov/dot Temporary Sidewalk Extension Design Goals 2 nyc.gov/dot 1. DETECTABLE WARNING STRIP AT EDGE Provide DWS for the full width of the crosswalk, parallel to the edge of sidewalk extension Flatbush Ave, Brooklyn Early tests used standard size mats that didn’t provide information for the full width of the pedestrian space at the crosswalk 7 nyc.gov/dot Delancey St, Manhattan 2. DETECTABLE WARNING STRIP COLOR Yellow might not stand out against “truffle” as it wears Madison Square, MN Union Square, MN Gray mats didn’t provide necessary contrast with color of surface Red chosen – high contrast 8 nyc.gov/dot Coney Island, Brooklyn 3. DETECTABLE WARNING STRIP IN PEDESTRIAN RAMPS Bay St, Staten Island Ensure there’s DWS on both sides of crosswalk Remove existing DWS in pedestrian ramps leading to temporary sidewalk extensions Flatbush Ave, Brooklyn 9 nyc.gov/dot 4. GRANITE BLOCK AT CROSSWALK Markings Concrete Layout Install at edge of crosswalk to provide directional information Madison Square, Manhattan 10 nyc.gov/dot 5. EDGE OBJECT SPACING Delineators, granite blocks and planters Provides information about where not to cross 3rd Ave and 138 St, The Bronx 3’ within 15’ of crosswalk 5’ remainder of edge Madison Square, Manhattan 11 nyc.gov/dot Considerations 3 nyc.gov/dot DETECTABLE WARNING STRIP MATERIAL Union Square, MN Flatbush Ave, Brooklyn User testing Rubber mats epoxied & screwed to asphalt came loose quickly Poured in place liquid DWS holds up & can be applied to all surfaces 13 nyc.gov/dot MAINTENANCE Excessive delineators present purchasing and maintenance issues Brooklyn College Delineators must be 11’ off curb for street sweeper/plow access if there isn’t a maintenance partner 3rd Ave and 138 St, The Bronx nyc.gov/dot CAPITAL BUILD OUT After SIP SIP projects go onto Capital pipeline list 5-10 year process, including funding prioritization, design and construction After Capital Allen-Pike Streets, Chinatown, MN 15 nyc.gov/dot New Treatments Under Investigation 4 nyc.gov/dot SHARED STREETS Madison Square, Manhattan Rigid plastic lozenge tiles 17 nyc.gov/dot AT-GRADE BIKE PATHS Investigating material options 5310 grant application for dedicated research staff East River Greenway, MN 18 nyc.gov/dot THANK YOU!
