Several years ago the FHWA Work zone Mobility and Safety program did a fact sheet on Communicating Work Zone Information to Truckers in North Carolina - http://www.ops.fhwa.dot.gov/wz/practices/factsheets/factsheet10.htm. In addition, there was a Talking Freight webinar on Freight and Work Zones in June 2007, with a presentation from NCDOT. The presentations from this webinar are on http://www.fhwa.dot.gov/freightplanning/07talking.htm, under June 20. It seems that North Carolina has done a lot in this area and may be a state to contact for more information. -----Original Message----- From: FHWA Freight Planning [mailto:[log in to unmask]] On Behalf Of Jose Holguin-Veras Sent: Thursday, September 09, 2010 1:41 PM To: [log in to unmask] Subject: Re: Reducing Work Zone Truck Fatalities 5-6% is typically the percent of trucks in total (day + night) traffic. At night, and particularly at interstates, it is larger. Are the 5-6% figures for total or only for night traffic? My sense is that this may have an impact on your analysis. jhv On 9/9/2010 1:21 PM, Dale A Tabat wrote: > All, > Both nationally and in the State of Washington, 22 percent of > fatalities occurring in highway work zones from 2002 to 2009 involved freight trucks. > The average percentage of trucks in Washington State highways is 5-6 > percent so heavy trucks are over represented in work zone fatalities. > WSDOT and agencies are looking to perform root cause analysis of the > problem to focus potential solutions on elements that most > significantly contribute to the problem. > > I am interested in obtaining information related to this research and > would appreciate any work being done or completed. > > Are other states doing analysis in this area? > Are other states interested in this problem? > > Thank you, > Dale A Tabat > Truck Freight Program and Policy Manager Washington State DOT > [log in to unmask] > > -- Jose Holguin-Veras, Ph.D., P.E.
