Another consideration is the amount of overall Washington highway fatalities that had heavy truck involvement. If heavy trucks are over-represented in non-work zone fatalities by a similar amount, than some of the root causes may be relevant beyond work zones and you might be able to learn something from examining non-work zone crashes as well. Some State DOTs that do extensive work zone crash analysis and might be helpful for ideas are Ohio, Florida, and New York. Additionally, there is information from a Kansas DOT study of major causes of work zone crashes - see http://www.ops.fhwa.dot.gov/wz/resources/final_rule/data_examples.htm -----Original Message----- From: Symoun, Jennifer E. [mailto:[log in to unmask]] Sent: Thursday, September 09, 2010 2:38 PM To: FHWA Freight Planning Subject: RE: Reducing Work Zone Truck Fatalities 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.
