Pedestrians in NCDOT Work ZonesPedestrian Accommodations Directive Signed by Tim Littlein July 2018 Became effectiveimmediately forprojects in allphases ofdevelopment andconstruction.5

Pedestrians in NCDOT Work ZonesPedestrian Accommodations Directive Governs the level ofaccommodation for PedestrianTraffic in Work Zones based onPedestrian Volumes. Requires that active pedestrianmovements be maintainedthroughout construction. Requires the use of ADAcompliant traffic controldevices along the sidewalk.6

Pedestrians in NCDOT Work ZonesProject Development Team RolesCommunity Studies Conduct site visits Document the presence, nature,and volume of pedestrian activity,as described by the CommunityImpact Assessment guidelines7

Pedestrians in NCDOT Work ZonesPedestrian Counts Counts can be ordered throughConnect NCDOT Traffic SafetyUnit website Must be approved and standardturn around time is 2 weeks Average per day over 7-daycontinuous count required Must be able to identifypedestrians with mobility andvisual disabilities Order counts when theperceived volume is high, notwhen it’s very low8

Pedestrians in NCDOT Work ZonesDetermining the Level of Pedestrian AccommodationFour Levels of Accommodation1) Absence of Need Less than10 Peds/Day AND no existingfacilities2) Basic 10 to 99 Peds/Day orexisting facilities present3) Moderate 100 to 499Peds/Day4) Full 500 or more Peds/Day9

Pedestrians in NCDOT Work ZonesProject Development Team RolesProject Management With Community Studies,determine required level ofpedestrian accommodation Ensure pedestrianaccommodation level getsincluded in project planningdocument and/or projectcommitments. Ensure that pedestrianaccommodation is includedin the project scope of work10

Pedestrians in NCDOT Work ZonesProject Development Team RolesTMP Designer Design a TransportationManagement Plan in accordancewith the level of accommodationneeded If possible, WALK the projectarea to determine existingconditions and document, asnecessary. It may be the onlyopportunity before constructionbegins11

Pedestrians in NCDOT Work ZonesSite VisitsThings to look for Existing sidewalks and/or wornpaths (document existing ADAfeatures) Pedestrian generators andattractors such as schools, busstops, parks, proximity ofcommercial and residential areasUse local knowledge Communicate with regional trafficengineer and Division staff todetermine pedestrian activity Contact local service providers forcitizens with disabilities12

Pedestrians in NCDOT Work ZonesSite VisitsDetermine continuity of Existing Sidewalks (i.e. do they connect tothe next intersection? or simply end) Noncontinuous sidewalks are not expected to be maintained However, if there is a worn foot path that continues from thesidewalk and connects somewhere then it must be maintained13

Pedestrians in NCDOT Work ZonesSite Visits Check the condition of the existing sidewalk for:– Uneven/Damaged sidewalks due to tree roots, settlement, and other issues– Obstructions in the path such as power poles or trees14

Pedestrians in NCDOT Work ZonesSite Visits2) Evaluate Existing Sidewalks for ADACompliance Width of sidewalk (3’ Min, howeveranything less than 5’ has to have“passing” spaces every 200’ ) Running slope of sidewalk (5% or less) Cross slope of sidewalk (2% or less)15

Pedestrians in NCDOT Work ZonesSite VisitsCheck for existing curb ramps– Detectable edging– Is there a flat surface to turn around at thetop of the ramp?– Is there a receiving ramp on the other sideof the road?– What direction does the ramp direct users?16

Pedestrians in NCDOT Work ZonesSite VisitsMost existing sidewalks are not ADA Compliant The work zone does not have to be brought up to fullADA standards during construction– Any existing ADA features should be present in any temporaryfacility– Any traffic control devices that are used to maintain pedestrianaccess must be ADA compliant.17

Pedestrians in NCDOT Work ZonesTakeaways from this Segment The level of pedestrian accommodation should be determinedas early as possible in the process (in planning) Order pedestrian counts when you think the volumes may behigh enough to fall into the moderate level of accommodation The level of pedestrian accommodation should be captured ina firm’s scope of work and manday estimate Existing ADA features of a sidewalk should be noted as earlyas possible so that those features are known by all and tohelp avoid surprises during TMP design18

Pedestrians in NCDOT Work ZonesBest Practices for TMP Designers Understand the level ofpedestrian accommodationrequired on each roadway. Absence of Need:– Nothing needed in TMP atstart of project.– But as sidewalks get built bythe project, those facilitiesmay need to follow Basicaccommodations.19

Pedestrians in NCDOT Work ZonesBest Practices for TMP Designers Basic Accommodations– ADA compliant devices needto be used to close existingfacilities. Type III Barricadesare NOT ADA compliant.– Permanent facilities shouldbe phased early. Existingfacilities on one side shouldbe maintained untilpermanent facilities can open.– Off-site detours (up to ½ mileadditional length) may beused.– Pedestrian transport serviceare another option, but pickuplocations need to be planned.20

Pedestrians in NCDOT Work ZonesBest Practices for TMP Designers ModerateAccommodations– Maintenance of existingfacilities becomes moreimportant.– On-call transport serviceis not permitted -Recurring transport (suchas a bus on a schedule)is required.– Offsite detours are stillpermitted (up to ½ mileadditional length)21

Pedestrians in NCDOT Work ZonesBest Practices for TMP Designers Full Accommodations– Peds should bemaintained on-site at alltimes.– Ped facilities duringconstruction MUST meetcurrent ADA standards– May require ADAupgrades as Phase 1 ofconstruction– If on-site peds cannot bemaintained, recurringtransport is requiredevery 20 minutes.– Offsite detours are NOTpermitted.22

Pedestrians in NCDOT Work ZonesADA Compliant Pedestrian TCD’s Pedestrian Channelizing Devices Show on plans to close sidewalksand/or channelize pedestrians whenaway from traffic. Paid by LF, pay for SIDEWALKCLOSED signs separately asBarricade Mounted Signs. Water-filled or portable concretebarrier (WFB/PCB) can be used inplans to separate peds from traffic. Ifused for this, pay as WFB/PCB, NOTPedestrian Channelizing Device. WFB/PCB will need proper end unitswhen in vehicle clear zone. Contractor can use WFB/PCB in lieuof Ped. chan. devices with Engineer’sApprovalPedestrian ChannelizingDevices – Away from TrafficWater-filled Barrier –Adjacent to Traffic44

Pedestrians in NCDOT Work ZonesADA Compliant Pedestrian TCD’s Audible Warning Devices Must be used in conjunctionwith pedestrian transportservice at sidewalk closurelocations. Must also be used at allpedestrian path changes(on/off-site detours) if existingaudible devices are on project,such as locator tones at trafficsignals. Paid by Each, Quantity ismeasured as the maximumnumber on the job at any giventime.45

Pedestrians in NCDOT Work ZonesADA Compliant Pedestrian TCD’s Temporary CurbRamps Used wheneverpedestrians musttraverse an existingcurb or other gradechange. Paid by Each.
