practices will help the states more effectively address workforce
issues and contribute to the development and effective management
of a knowledgeable, skilled and motivated state DOT workforce.
This study identified, researched, analyzed and documented
state innovative practices for workforce development. The
results have been incorporated in the FHWA workforce development
website at www.nhi.fhwa.dot.gov/transworkforce. (NCHRP Staff:

Task 151, FY 2002, "Transportation Security"
(Consultant: Various). This project produced material needed
by AASHTO's Security Task Force and state DOTs. Two contractors'
reports, prepared for the AASHTO Security Task Force with
funding provided through the National Cooperative Highway
Research Program, are available on the AASHTO web site at
http://security.transportation.org/community/security/guides.html.
"A Guide to Highway Vulnerability Assessment for Critical
Asset Identification and Protection" was prepared by
Science Applications International Corporation, and "A
Guide to Updating Highway Emergency Response Plans for Terrorist
Incidents" was prepared by Parsons Brinckerhoff--PB Farradyne.
Contract staff support to the AASHTO Security Task Force is
provided by TransTech Management, Inc. (NCHRP Staff: S.A.
Parker)
Task 147, FY 2002, "Update of the Design Guidelines
for the Control of Blowing and Drifting Snow" (Dr.
Ronald D. Tabler). This study updated the 1994 publication
"Design Guidelines for the Control of Blowing and Drifting
Snow." This update will provide enhanced information
for the design of effective and economical measures for controlling
snowdrifts and reducing the concentration of snow in the air.
The project required a substantially larger effort than initially
anticipated. The project is complete. The final report was
prepared on a CD-ROM and will be furnished to SICOP for posting
on the SICOP website. (NCHRP Staff: A.N. Hanna)
Task 117, FY 2000, "Benefit/Cost Study of RWIS and
Anti-icing Technologies" (S. Edward Boselly, III).
The study has provided the operations staff of highway agencies
with benefit/cost analyses of applying RWIS/Anti-icing technologies.
A final report was received in March 2001. Copies were forwarded
to the chair and members of the AASHTO Highway Subcommittee
on Maintenance. (NCHRP Staff: A.N. Hanna)
Task 83, FY 1997, "Guide for Snow and Ice Control"
(Weather Solutions Group). There is a great disparity in the
technology and quality of winter maintenance as it is performed
by the different states and municipalities. There is a need
to develop a guide manual for snow and ice control that addresses
the different aspects of winter maintenance. The objective
of this project was to develop a guide for ice and snow control.
A draft outline for this guide manual was developed under
NCHRP Project 20-7, Task 71, "Winter Maintenance Program,"
and finalized based on the results of a national workshop
held on April 1-2, 1996. The project is complete; a guide
manual that addresses issues pertaining to materials, equipment,
operations, personnel, administration and management, and
related special considerations has been prepared and forwarded
to AASHTO headquarters for distribution to the members of
the AASHTO Highway Subcommittee on Maintenance. (NCHRP Staff:
A.N. Hanna)
Task 71, FY 1994, "Winter Maintenance Program"
(Mr. L. Gary Byrd). The AASHTO Subcommittee on Maintenance
(SCOM) identified the development of a winter maintenance
program (WMP) as an important task based on the recommendations
of an international winter maintenance technology scanning
tour. The goals of the proposed WMP are to (1) sustain or
improve levels of winter maintenance service with significant
benefit/cost improvements, (2) provide an enhanced level of
environmental protection, and (3) place technology in service
on operational maintenance section within two winter seasons.
This project provided the initial steps toward developing
a WMP by establishing a broadly based winter maintenance panel
and conducting a national workshop on April 1-2, 1996, in
Washington, DC. The final report provides a comprehensive
outline of the proposed Snow and Ice Control Guide and outlines
plans for initiating the proposed Snow and Ice Pooled Fund
Cooperative Program. The report has been transmitted to the
AASHTO Highway Subcommittee on Maintenance and to the workshop
participants. (NCHRP Staff: A.N. Hanna)
