Anti-Icing Strategies Being Implemented in the States
Liquid application being applied to prevent road from becoming icy.
On Oct. 10, 1995, FHWA hosted a symposium on Test and Evaluation Project No. 28, "Anti-Icing Technology", in Estes Park, Colorado. The symposium culminated in a 2-year field test and evalua tion of various anti-icing technologies that were identified under the Strategic Highway Research Program. It provided a dynamic forum for winter maintenance managers and specialists to exchange information across State lines and gain insights into this critical area of highway maintenance.
Over 200 interested participants representing a comprehensive cross-section of the highway commu nity attended the symposium. They included 27 State highway agencies as well as many counties and towns, academic institutions, consultants, product suppliers, and equipment manufacturers. Discussions with the audience indicated that the implementation of anti-icing technologies and practices have advanced throughout the Nation. Many of the maintenance managers and field per sonnel had expressed concerns that information and strategies on winter maintenance control be presented at the symposium to help them implement effective anti-icing programs. Details on anti -icing can be found in FHWA's Manual of Practice for Effective Anti-Icing , FHWA-SA-95-XXX.

Human Factors Handbook Available for Designing Advanced TMC's
The Intelligent Transportation System (ITS) era is bringing advanced technology to Traffic Manage ment Centers (TMC's). New and existing TMC's, for example, are expanding their roles and updat ing their capabilities with an increase in automation. The introduction of automation and complex information display and control systems could create unexpected problems for system operators and increase the likelihood of error. The impact of automated systems and the level of system complexity on operator performance should be addressed to increase operator efficiency.
To investigate TMC design objectives from a human factors perspective, researchers at the Georgia Tech Research Institute (GTRI) are exploring the roles of computers and humans within ITS traffic management systems. The project is for an FHWA research program entitled "Human Factors in Advanced Traffic Management Systems (ATMS)." This comprehensive program of human factors research was started in 1993.
A primary product of this ATMS project will be a comprehensive design handbook of recommenda tions and human factors guidelines for designers and users of future TMC's. The handbook is being developed in two phases. In the first phase, GTRI obtained analytic data for a first-edition handbook.
Information in the first-edition is based on lessons learned from (1) top-down system analysis; and (2) analytic data obtained from visits to about 24 TMC's as well as interviews with TMC experts in the United States, Canada, and Europe. The handbook will be modified based on inputs from the study's second phase. During this phase, GTRI will obtain empirical data by testing technologies and conducting comprehensive human factors experiments on a TMC research simulator. The resulting final handbook of design standards and guidelines will be available during the spring of 1997.

Congestion Pricing Conference Includes Report on State Route 91 Project
On October 17, 1995, FHWA's Congestion Pricing Team conducted a 1-day workshop in Philadelphia, Pennsylvania. The workshop was held to highlight recent activities of the Congestion Pricing Pilot Program and stimulate discussion of key implementation issues. The program, authorized by ISTEA, now has 10 active projects throughout the United States.
Two are pilot implementation projects, seven are pre-implementation efforts designed to lay the groundwork for potential future applica tions of congestion pricing, and one is a privately-funded implementation project for the automated express lanes on State Route 91 (SR91) in Orange County, California. FHWA is committing funds for post-implementation monitoring and evaluation of the SR91 project.
Reports on the progress of these projects were a key feature of the workshop. Participation by FHWA's project partners generated lively discussion. The report on the SR91 project was of great interest since this privately-funded and operated toll facility will be the first one in the United States to use an electronic variable toll system to manage traffic flow. The facility, which was built in the median strip of SR91, was opened in December 1995.
Other features of the workshop included breakout sessions on building partnerships, public outreach research, advanced technology, and evaluation. Time was also devoted to open discussion of poten tial new congestion pricing applications in the northeastern United States. Response from the 75 workshop participants was extremely positive. Several activities, including additional regional workshops, are being planned for later in 1996 and 1997. More information on these activities, the Philadelphia workshop, and other congestion pricing issues, is available from the Congestion Pricing Team, (202) 366-0570.

International Bridge Maintenance Course Proves Successful
Sponsored by the U.S. DOT, FHWA, and the National Highway Institute (NHI), the International Bridge Maintenance Training Course was a big success. It provided practical training for maintain ing, repairing, and rehabilitating highway bridges under a range of conditions. It included 5 days of classroom instruction and 4 days of on-site field visits to demonstrate concepts learned in the class room.
At the end of the course, the international participants were fully prepared to apply their knowledge to actual bridge maintenance operations in their home countries. A total of 25 people, representing 12 countries, took part in the course.
The course was conducted from September 18 to 28 at the Double Tree Tysons Corner Hotel in Falls Church, Virginia. The lead instructor and developer of the course was Ron Purvis from Wilbur Smith Associates. Mr. Purvis is a leading specialist in highway bridge technology. The course covered such bridge maintenance topics as structural mechanics, condition assessments, traffic maintenance, environmental issues, and worker safety. As part of the field visits, the participants reviewed operations at the Virginia Research Council, TFHRC, Chesapeake Bay Bridge, and the Virginia DOT. The course is the first in a series of courses designed for an international audience.

FHWA Associate Administrator for Policy Ventures to Australia for APEC Meeting
The coastal city of Sydney was the host venue for the Asia-Pacific Economic Cooperation's (APEC) Eighth Transportation Working Group Meeting in September. The Transportation Working Group is 1 of 10 topic groups formed within this coalition of 18 international economies. In Sydney, Gloria J. Jeff, FHWA's Associate Administrator for Policy, chaired the Transportation Working Group's steering committee meeting for the Congestion Points Study. This intermodal study will identify major transportation bottlenecks at airports, seaports, and land access points in the Pacific Rim, and devise strategies to mitigate them. The scope of the study includes institutional, regulatory, and operational barriers, as well as physical infrastructure deficiencies that impede the flow of passengers and cargo.
The proceedings of the steering committee meeting featured progress reports on transportation industry focus groups conducted throughout the Pacific Rim in the second phase of this three-phase study. The outcome of U.S. meetings conducted with State, local, and private transportation provid ers and customers in Los Angeles, San Francisco, and Seattle will be incorporated into a phase II final report. The final phase of the study will culminate in late 1996 with a report featuring a best practices manual and innovative congestion mitigation strategies.
Associate Administrator Jeff also presented a paper on the "National Freight Partnership," an effort initiated by FHWA and the U.S. DOT's Office of Intermodalism to enhance communication and interaction between Government and the transportation industry. This innovative public/private collaboration is designed to address cargo movement issues, remove obstacles to efficient freight transport, and enhance communication among private sector transportation freight users and provid ers and public transportation agencies.
Ms. Jeff's contribution to the Transportation Working Group highlighted FHWA's accomplishments in an international arena and created a dialogue and an information-sharing network with other Pacific Rim countries.

Highway Capacity Support Team Established
FHWA is sponsoring efforts to provide technical support for the Highway Capacity Manual (HCM). The HCM contains procedures for determining the capacity and levels of service for a variety of highway facilities. The procedures are widely used to design and evaluate facilities throughout the Nation. The HCM is the product of the Transportation Research Board's Committee on Highway Capacity and Quality of Service (HCQS). The committee has developed three editions of the HCM since 1950 and most recently released the 1994 edition which contains major updates to the 1985 edition. Over 10,000 copies of the 1994 HCM, which was actually released in January 1995, have been sold to date.
