Portable Changeable Message Signs (PCMS)  Overuse of “ROAD WORK AHEAD” and “(USE) CAUTION”  Using dependent message fragments  Must read both panels to get entire message  Misaligned PCMS makes them illegible  In need of repair – Burned out LEDs

Need more informative messages Ensure visibility

Avoid using message fragments on a single panel…

First message… …Second message… Use standard rigid sign, Or non-dependent messages: TRUCKS ENTERING 450 FT WORK VEHICLES AHEAD

First message… …Second message…

 Missing LEDs can render a PCMS illegible.

Bike/Ped/ADA Accommodation  No significant gains made in accommodation or design  Gravel surfaces not ADA-compliant nor bicycle-friendly  More guidance to keep bikes out of work area  More guidance for peds in urban work zones

Close bike lane completely, Redirect bicycles, Warn motorized traffic of bike presence

Close sidewalks w/ proper signing/devices Provide safe, efficient, signed, ADA alternate route Provide additional signing for motorists, as needed

Close sidewalks w/ proper signing/devices Provide safe, efficient, signed, ADA alternate route Provide additional signing for motorists, as needed If peds must use roadway, need ADA ramps from curb Need channelization devices between traffic and peds Could alternate route use existing pavement in front of local businesses?

Pavement Markings  Additional temp. markings needed until permanent can be applied  Faded striping in curvilinear sections  Reflective markers need better maintenance  Markings not matching Regulatory signing (“No Lane Changes”, “Do Not Pass”)

Channelization devices and/or temporary pavement markers should be used to substitute for permanent markings: Nighttime/Overnight Freeways or High ADT

Badly damaged/missing markers mean very poor nighttime visibility Contractors required to maintain/replace damaged markers/markings

With permanent markings in place… With poorly maintained temporary markings in place…

Double-solid striping begins at regulatory sign Signing and striping must match for enforceability

TEMPORARY SIGN DESIGN  Sign Legend, Color, Sizes  Wordy messages  Structurally questionable (crashworthy)  Complicates enforceability  Detour Signing  Recommend more detailed signing plans  Incorrect Application  Use correct design for corresponding message

TEMPORARY SIGN IMPLEMENTATION  Sign Spacing  Too close together (temp. & existing)  Blocking critical guide, service signing. See TM800  More Signs as per Specification  Additional “Abrupt Edge” and “No Center Stripe” signs  “Road Work Ahead” and “End Road Work” signs  In the middle of projects  Moved as work moves  Enforcement relies on these signs. Defines work zone limits.  “Clipped” Signs on Barrier Sign Supports  Phased out. Gone as of June-Nov ‘09, Standard Drawings  Repeated improper design and usage  Use 36”x36” sign from now on

Largely positive comments regarding traffic flow and delay through work zones Comments eluded to delays or slowed traffic stemming from:  “Gawk” effect  Tricky traffic merges or alignment shifts  Confusing detour (signing?)  Contractor operation oversights  Gravel staged surfacing created very slow traffic  Flagging operations

Temporary Signing  Quality was good – visibility, sheeting condition  Particularly high quality roll-up signs

Channelization Devices  Plastic Drums in excellent condition  Drum Tapers excellent (especially for freeway lane closures!)  Overall good device spacing  Barricades in good condition

Temporary Concrete Barrier  Good condition & alignment  Use of “screening” helps prevent “gawking” & improves speeds  Increased use of Reflective Barrier Panels helps delineate barrier

Pavement Markings  Most cases, striping was fresh, clear, well placed  Markers notable in freeway crossovers and on-site diversions  Reflective markers in good shape and alignment  Flexible markers need more attention

No unreasonable delays experienced through 60 projects. Average travel speed through majority of work zones was at or near the posted speed. For Flagging operations:  Statewide: Max. = 10 min. Average = 2.1 min. (for 16 projects)  By Region: For Temporary Signals:  Statewide: Average = 2.5 min. (for 7 projects)
