1. Maintenance and Temporary Traffic Control
Key Points: Module 7 includes 43 slides.

2. What Will be Discussed
Temporary Traffic Control for Pedestrian Facilities
Appropriate Barricades
Alternate Routes
Public Information
Key Points: This module includes a lot of information and design ideas that are good general design for pedestrians but also apply to people with disabilities. In the interests of saving time, some of these slides could be deleted or hidden to focus the presentation more directly on issues for people with disabilities 2

3. MUTCD Provisions
MUTCD, Part 6D When existing pedestrian facilities are disrupted, closed, or relocated in a TTC zone an alternate route must be provided the temporary facilities shall be detectable and include accessibility features consistent with the features present in the existing pedestrian facility
Key Points: These two slides are just a sampling of the new language in the MUTCD that requires accessibility during construction activities. Many of the examples in this module are related to provisions in the MUTCD.

4. Temporary Pedestrian Routes
Includes:
Sidewalks
Shared Use Paths
Curb Ramps
Crosswalks (marked and unmarked)
Pedestrian signals
Access to transit stops and shelters

5. Tools to Minimize Impacts
Construction Phasing
Use of Detailed Plans
Signing and Staging of Work
Accessible Alternate Routes
Effective Barriers
Inspector Training
Public Information
Key Points: With planning up front, the impact of the construction or maintenance activity can be minimized for pedestrians and cyclists. Consider:
Phasing – build new sidewalk first so that its available once old sidewalk is closed for reconstruction of the roadway. Ensure conduit, electrical equipment for signals, other utilities are in place before new sidewalk is poured.
2) Staging of Work – always consider primary pedestrian flow and ensure access is still available to adjacent properties, parking garages and destinations sites. Work on one side of street at a time, or one corner at a time.
3) Alternate Routes – identify the available alternate route every time a section of sidewalk or bikeway is closed. Don’t assume there is one.
4) Public Information – contact managers of office buildings, shopping centers, public facilities, transit providers in advance to discuss project, develop traffic control plan together. You may be surprised at their willingness to work with you to expedite the construction project. Utilize web, media to inform public. Take advantage of new tools such as GMaps Pedometer to evaluate alternate routes and make maps.
5) Try to schedule work in off-peak times, such as when schools out, snow birds have migrated north, non-hurricane season if an evacuation route, or off season for sporting venues, parks.
6) Try some of the new equipment for sidewalk maintenance, such as a burr grinder, which can alleviate variations in concrete slab elevation without replacing the whole section of sidewalk.

6. Construction Phasing Build new sidewalk early in project
When replacing side-walks, work on one side of street at a time, length that can be replaced next day
On bridges, build sidewalk wide enough to accommodate two-way bicycle and pedestrian travel (8’ min.)
Maintain accessible crossings through work zone

7. Construction Phasing Staging to Maintain Alternate Route
Sidewalk Open
Work Area

8. Use of Detailed Plans Large scale (1”=5’)
Show all elevations, dimensions and curve data
Use to show alternate routes
Key Points: Very few places use this sort of detailed engineering in order to comply with ADA standards

11. Signing and Staging of Work Typical Construction Site Problems
“Sidewalk Closed” sign placed too far down the block
No alternate route
Barrier does not provide adequate warning

12. Signing and Staging of Work Better Option!
“Sidewalk Closed” sign placed in advance of construction impact
Does not block access to ramp or push button
At accessible, controlled crossing point
Add photos from Thomasville Road.

13. Accessible Alternate Routes Evaluating Alternate Routes
Accessible pedestrian facilities available
Reasonable length
Continues to provide access to services, destinations
Volume of traffic acceptable
Maintains quality – shade, scenic values, perceived safety
Key Points: In developing an alternate route, consider the length, whether or not bicycle and pedestrian facilities are available, is access still available to services, businesses, destinations such as parks, schools, and other public places. Consider the volume of traffic on the proposed route, and whether or not there are safe places to cross the street. In warm climates, shade is especially important, as is a person’s perception of personal safety. Its best if the detour route is commonly traveled, and can easily be patrolled by law enforcement, especially if its intended to be used after dark.

14. Accessible Alternate Routes Typical Construction Site Problems
Pedestrian zone blocked by materials or equipment.

15. Accessible Alternate Routes Typical Construction Site Problems
Access to curb ramps, crosswalks restricted
Alternate routes not provided
Pedestrians forced to take circuitous, unpredictable or dangerous routes

16. Accessible Alternate Routes
Temporary ramps and boardwalks ensure smooth continuous surface

17. Accessible Alternate Routes
Provide temporary curb ramps where needed

18. Accessible Alternate Routes Curb Cut Ramps
Identify temporary locations in the plans

19. Accessible Alternate Routes Placement of Signage in Work Area Maintain Clear Sidewalk
Use signs of an appropriate scale, type to convey message
Limit signs placed on sidewalk to those needed to maintain pedestrian route
Key Points: TTC signs for roadway related work often impact sidewalks. Plan ahead to what type of signs can be used given the available space outside of the travel lane. The portable lane closure sign shown has minimal impact on sidewalk clearance, especially since the sidewalk is constricted by guardrail and picket railing. Very little consideration though was given to the impact to pedestrians with this variable message board with its safety message. Purpose of barrels?

20. Effective Barriers
Accessible barricades should be provided when construction occurs in the public right-of-way
Barriers defining the alternate route should:
Be 36-42” high & continuous within 6” of the ground
Extend perimeter of construction site or entire length of alternate route

21. Provide crash-worthy barriers when a temporary route is in the roadway
Effective Barriers
Key Points: Good job of providing continuous edge at ground level with barrier wall and curbing, plywood ramp. However, wooden barricade in background needs bottom edge.
Photo Location: Washington DC
Provide crash-worthy barriers when a temporary route is in the roadway

22. Effective Barriers Typical Construction Site Problems
Ineffective barriers (plastic tape) around site doesn’t provide detection
Key Points – Not detectable with a cane until already in work zone, no continuous guidance at ground level (or anywhere), if shoreline along edge of building, may walk right into point of barricade. Good that they are lighted with flashing beacon.

23. Effective Barriers
Effective detectable barricade at curb ramp to indicate a temporary crosswalk closing.

24. Inspector Training Construction Engineering Inspection
Tight construction tolerances needed
Inspections: actual measuring (not visual)
Train contractors, inspectors, concrete finishers, signal subs
Include training on accessibility requirements in certification for Work Zone Supervisors
Key Points: For inspections, it is best to use a digital level on the forms before concrete is poured. Ensure that the carpenters, concrete finishers, and inspectors learn how important the 8.3% and 2% standards are for people with mobility impairments.

25. Public Information
Contact facility managers, transit agencies, schools, parks, public service providers
Develop web sites, esp. for major projects, heavily used facilities, shared use paths
Web site should be accessible
Post in advance of construction or maintenance activity
Map detours and post on web sites, at project location
Send announcements to community radio reading service
Key Points: With planning up front, the impact of the construction or maintenance activity can be minimized for pedestrians and cyclists. Consider:
Phasing – build new sidewalk first so that its available once old sidewalk is closed for reconstruction of the roadway. Ensure conduit, electrical equipment for signals, other utilities are in place before new sidewalk is poured.
2) Staging of Work – always consider primary pedestrian flow and ensure access is still available to adjacent properties, parking garages and destinations sites. Work on one side of street at a time, or one corner at a time.
3) Alternate Routes – identify the available alternate route every time a section of sidewalk or bikeway is closed. Don’t assume there is one.
4) Public Information – contact managers of office buildings, shopping centers, public facilities, transit providers in advance to discuss project, develop traffic control plan together. You may be surprised at their willingness to work with you to expedite the construction project. Utilize web, media to inform public.

6) Try some of the new equipment for sidewalk maintenance, such as a burr grinder, which can alleviate variations in concrete slab elevation without replacing the whole section of sidewalk.

26. Los Gatos Creek Greenway San Jose, CA
Key Points: Is Detour Route a reasonable distance? What are some of the constraints? RR, location of traffic signals to cross larger roadways, shade, volume of traffic. In a commercial or urban setting, an additional 0.7 mile detour would be excessive, but works for this regional trail system.
Greenway work zone is 0.5 miles.
Pedestrian Detour Route is 1.2 miles
