  1. Maintenance and Protection of Traffic (MPT) – HDM Ch 16

  2. Goal • Safe and adequate maintenance of traffic

  3. Issues • Where is traffic going to go? • Off-site detour • On-site detour • Staged Construction • Temporary roads and ramps • Temporary structure • When can contractor work? • Anytime? • Non-peak hours? • Night? • What signs/markings are needed? • Consistency with MUTCD

  4. Others • Do peds and bicyclists need accommodation? • Are dedicated police traffic services needed? • What will be sequencing of MPT? • What are costs? • Can capacity and LOS be maintained?

  5. Off-Site Detours • Use of state, county or local roads • Detour lengths? • Must look @ improvements necessary to handle increased traffic volumes: • Pavement widths and thicknesses • Structures • Guide Railing • Signs/Signals • Lateral Clearances

  6. On-Site Detours • Staged Construction (build a portion at a time) • Temporary Roads and Ramps • Temporary Structures • Misc: • Must maintain driveway access • Maintain one or two lanes? • Should detours be paved?

  7. Toolbag • Flaggers • Pavement markings • Signs • Channelizing Devices (cones, tubular markers, drums, barricades) • Barriers • Arrow panels • Lights • Traffic Signals • Rumble Strips

  8. Show Overheads Must consider how phasing will impact placement of materials Cross-sections can be used as a tool

  9. Facilities for Bikes – HDM Ch 17

  10. Bicyclists • Improvements: • Grates-eliminate or use special grates • RR crossing-90 degree crossings or reduce flangeway width • Pavements-Eliminate irregularities • TCS-Check clearance interval

  11. Bicycle Provisions • Wide Curb lanes • Urban areas • 14’ of usable pavt width (wider if possible) • Shoulders • Rural areas • >= 4’ (wider if vehicle speed > 35 mph, >5% HV, obstructions, children, ped use of shoulders

  12. Shared Lane

  13. Bicycle Provisions • Bicycle Lane (portion of roadway designated for bicyclists) • Used on bicycle routes mapped by MPO’s • 4’ min. width • Can be conflicts • Bicycle Path (bikeway physically separated from veh. Traffic) • Design similar to road

  14. Bike Lanes

  15. Bike Lane w/ Parking

  16. Facilities for Peds – HDM Ch 18

  17. Pedestrians-Importance: • 2000 Census: • New York State--30% of residents don’t own cars • Estimated pedestrian AADT-- 20 million trips • As population ages, expect more pedestrian use

  18. Pedestrians and Bicyclists By law, pedestrians and bicyclists can use unlimited access highways and streets. Low Volume Facilities-share roadway w/ vehicles High Volume Facilities-best to separate traffic streams • Reduce accident potential • Decrease travel time

  19. Maintenance • NYSDOT does not maintain sidewalks, bikepaths or bicycle parking facilities. • Local government agency must pass a resolution agreeing to maintain these facilities before they are built (new policy?)

  20. Assessing Needs-Land Use • Residential • Business/commercial • Mixed commercial/residential • Industrial • Recreational • Educational • Agricultural/Open Space

  21. Assessing Needs-Generators • Major employment centers • Schools • Parks • Shopping Centers • Residential Neighborhoods • Medical Centers • Colleges and Universities • Bus Stops • Transit Stations • Recreation Areas

  22. Existing Characteristics • Special User Groups • Trip Purpose • Frequency of Use • Volumes

  23. Existing Accommodations • Locations of walkways, bikeways, shoulders and worn paths • Incomplete systems • Existing signing • Existing conditions • Existing features than enhance/reduce feasibility • Existing Right-of-Way

  24. Others • Local plans • Accident History • Existing Site Characteristics: • Parking • Lighting • Crosswalks • Signals • Drainage • Roadway Surface Condition

  25. Pedestrian Facilities • Sidewalks • 5’ minimum (see next slide) • 2% cross slope • 7’ minimum near parking lanes • 6’-6” vertical clearance • Shoulders (if no sidewalks) • Greater than or equal to 4’ • Crosswalks • Traffic Control Features • Handicapped Accessibility Features

  26. Ped Accommodations Not Warranted • Peds prohibited by law • Cost disproportionate to need • Sparse Population-Absence of Need
