2 Overview of 2013 Work Zone Crashes Work Zone Safety Discussion TopicsOverview of changes included in the Virginia Work Area Protection Manual, Revision 1Overview of 2013 Work Zone CrashesOverview of Short Term Reduced Work Zone Speed Limit Request ProcessRevision 1 will allow thick aluminum signs versus the current thick sign.Section 6F.02
3 VA Work Area Protection Manual REVISION 1 Key DatesRevision Effective Date(s):April 1, 2015 – Daily OperationsJuly 1, 2015 – Projects bid on or after July 1, 2015Any project bid before July 1, 2015 will continue under the 2011 VA Work Area Protection Manual, without revision 1.
4 Portable Sign Supports Stands should be flush to the ground or roadway surface as possibleLegs fully extendedLegs are flush but must be extendedUnstableSection 6F.03
5 Portable Sign Supports Weight may be added to stabilize portable sign supports:Two drum collars on center of sign standA sandbag per leg weighing approximately 25 lbsTwo drum collar weights may take the place of four 25 lb. sandbags.Section 6F.03
6 Figure 6F-4, Vehicle-Mounted Signs for Temporary Traffic Control The WORK VEHICLE DO NOT FOLLOW sign may be replaced now with the WORK VEHICLE FREQUENT TURNS sign. All must be converted over by July 1, 2017.Section 6F.64
7 Appendix D Portable Changeable Message Signs Displays Appendix D was revised to provide uniformity across the Commonwealth by standardizing PCMS messages for temporary traffic control applications as shown in Chapter 6H. The new Tables are:PCMS Message for TTC ApplicationsUnacceptable Portable Changeable MessagesThe changes in Appendix D and based on meetings and recommendations by the Regional Work Zone Coordinators as well as field reviews and a review of adjacent stateDOTs.

10 2013 Work Zone Crash Statistics The following information helps explain what occurred in 2013 with work zone crashes statewide.Here’s just a graphic replication of where the crashes occurred in The following slides will explain more information about these crashes. . .
11 2013 Work Zone Crash Statistics WZ Crashes and Injuries20122013The good news first, we experienced 60 fewer WZ crashes in 2013 than we did in 2012, and a few less injuries . . .2012
12 2013 Work Zone Crash Statistics The bad news is we experienced 4 more fatal crashes, resulting in 21 fatalities, up from the previous year’s total of 12 crashes and 13 fatalities.A little closer to home, the 21 fatalities' also includes Trevor Blankenship, a consultant inspector working for the district Traffic Engineering section, and Kenterrious Christian, an employee of Pavemart Corp.* Includes a consultant inspector and a pavement marking contractor employee.
13 2013 Work Zone Crash Statistics Of the 3405 crashes last year, 469 were single vehicle crashes while 2935 were multi-vehicle crashes.Included in these numbers were 63 motorcycle crashes resulting in 67 injuries and 3 fatalities.Combined, there were a total of 7192 motorists involved in a work zone crash in 2013.Of the 3404 WZ crashes last year, 469 were single vehicle crashes, while 2935 were multi-vehicle crashes.Included in these numbers were 63 motorcycle crashes resulting in 67 injuries and 3 fatalities.Combined, there were almost 7200 motorists involved in a work zone crash in 2013.
14 2013 Work Zone Crash Statistics Two thirds of the 2013 crashes were by drivers 30 years old or older. That’s why it’s critical that we use devices that are visible, both day and night.Two thirds of the 2013 crashes were by drivers 30 years old or older.
15 2013 Work Zone Crash Statistics Crashes by MonthThe monthly breakdown of crashes looks like this, and an average of 9+ crashes a day occurring in WZ’s.Looking from June to the end of the year, crashes jumped to nearly 11 a day.Average of 9.3 crashes per day for the year.Nearly 11 crashes per day from June to December.
16 2013 Work Zone Crash Statistics This chart shows that a majority of our WZ crashes occurred on the Interstate system, more than all other crashes combined!

20 How’s it looking in 2014? Fredericksburg – 8 reviews Has it gotten any better in Looking at the following headlines from better roads, it doesn’t look like it!Fredericksburg – 8 reviewsNorthern VA – 3 reviewsCulpeper – 5 reviewsBristol – 9 reviewsLynchburg – 4 reviewsPurpose: To assess the effectiveness of VDOT’s work zone safety policies and procedures and compliance to the 2011 Virginia Work Area Protection manual
21 2014 Work Zone Reviews Fredericksburg – 8 reviews The following were positive findings during our review this year:Proper signage for lane closures and shoulder operationsEffective use of PCMS and Arrow BoardsAdequate taper lengths and placement of tapersUse of High Visibility Class 3 garments by workersPositive flow of traffic through the work zonesFredericksburg – 8 reviewsNorthern VA – 3 reviewsCulpeper – 5 reviewsBristol – 9 reviewsLynchburg – 4 reviews
22 2014 Work Zone ReviewsThe following were deficiencies related to paving operations found during our review this year:Missing “End of Day” signage (Bump, Uneven Lanes, Rough Road) on some operations and entrance ramps.Mixture of drums with improper sheeting.Nighttime glare from work lights.Maintenance of channelizing devices near exit ramps.Workers wearing high visibility garments improperly.
23 2014 Work Zone ReviewsThe following are some additional areas of concern expressed by VDOT staff:Channelizing devices placed into open travel lanes for the entire length of the lane closure versus moving out then back in along with the operation.Lane closures excessively longer than needed.Closing ramps too soon.Running ramp traffic across grass areas.Leaving out advanced STOP AHEAD or YIELD AHEAD signs on entrance ramps.
24 Short Term Reduced Work Zone Speed Limit Request Process Process finalized and published in December 2014Active upon initiationIs a result of direct inquiry from industry for streamlined processAvailable on VDOT website:
25 Short Term Reduced Work Zone Speed Limit Request Process Where does this apply?Work Zone duration is 72 hours or lessInterstate routesLimited access, muli-lane divided highwaysPosted speed limits of 55 MPH or greaterOther locations follow TE process
26 Short Term Reduced Work Zone Speed Limit Request Process Recommendations for work zone speed limits:Maximum reduction is 10 MPHMinimum work zone speed limit is 50 MPH (exceptions by RTE)Signs posted in accordance with VA WAPMAssistance from VSP for enforcement is encouraged
27 Short Term Reduced Work Zone Speed Limit Request Process Conditions where reduction may be warranted:Lane closure results in congestion that is expected to reduce operating speeds by at least 10 MPHPavement surface conditions induce vehicle instability (uneven, broken, ridged, etc.)Workers within 2 feet of travel lane for majority of work zoneLane width reductions resulting in travel widths less than 11’Work activity reduces available sight distance
28 Short Term Reduced Work Zone Speed Limit Request Process Additional items for consideration:Reduction only in effect during time of day when work zone is activeContractor will bear responsibility for covering uncovering existing posted speed limit signageContractor will bear responsibility for maintenance of records (date, time and termini) for reduced speed zoneAll traffic control devices will be installed based on the original posted speed limit
29 Short Term Reduced Work Zone Speed Limit Request Process Process steps for requests:Contractor completes fill it form (available on VDOT website) and submits to VDOT staff overseeing workVDOT construction staff reviews and solicits concurrence/approvals from Traffic Engineering staffReview times will be dependent on region specific practices – it is recommended to allow for at least one work week to process/review requestsOnce accepted by VDOT, contractor can install as part of work zone set up (see TTC-52.1)
