Remarks by Frank C. Herringer, Administrator of the Urban Mass Transportation Administration, at the American Transit Association's News Conference in Washington, D.C. on March 21, 1973.
The Safety Edge is a relatively low-cost countermeasure that can be applied in both asphalt and concrete paving operations. The Safety Edge has been promoted as a low-cost countermeasure to reduce the frequency and severity of rural roadway departure crashes. However, there is little information about the actual effectiveness of the Safety Edge in

Monitoring of the in-field performance of bridges and other structures has become a very valuable tool to the Iowa DOT Office of Bridges and Structures. There simply is no better way to understand how structures react to loadings than by physical monitoring and testing. There are a large number of monitoring tools that are commercially available. O

Canadian Pacific Railway (CPR) has been a leader in implementation of new friction control technology. Following earlier trials, we report the design, justification, roll out and early results of Total Friction Management (TFM) (GF plus TOR) over all high tonnage lines in Western Canada. Tools and processes needed for implementing TFM over a large

In 2003, BC Rail and Kelsan Technologies carried out a project to quantify the effect of Top of Rail (TOR) Friction Control on fuel consumption and Greenhouse Gas (GHG) emissions by reducing the curving resistance of a standard 3 piece North American truck. Measurable savings were based on monitoring changes in diesel fuel consumption, as well as m
...
The purpose of the work presented has been the development of an explanatory variable that characterizes train handling effects, allowing for the identification of changes in locomotive fuel consumption over a given territory (for example in response to Top of Rail Friction Modifier (TORFM) application) with improved confidence. To generate the exp

Managing the Top Of Rail (TOR) wheel/rail coefficient of friction, using friction modifiers (FM), has consistently demonstrated significant benefits to the heavy haul industry including fuel/energy savings, wheel & rail wear reduction, and reduced state of stress of the track infrastructure. Traditionally, the preferred method of FM application has
...
This paper outlines a new application technology for top of rail (TOR) train mounted friction control, particularly suited for captive freight fleets. The spray application system is mounted on a revenue-generating freight car located immediately behind the trailing locomotive. Compared with locomotive mounted systems [1, 2, 3], the new approach pr

This postcard describes two FHWA reports: "Best Practices for Corrosion Control and Mitigation" and "Industry-Recognized Corrosion Prevention Worker Certifications Effectiveness Evaluation."
Since construction of most of the major highway networks in the United States has already been completed, the majority of current highway work includes maintenance and rehabilitation of those highways, during which work zones are generated. In these areas disruptions to regular traffic flow are inevitable and the safety of road users and highway wo

Safety in highway work zones has been a major concern for many decades. Over the years, government agencies and highway industry have developed work zone safety training programs to educate general public, professionals, and government employers. Existing training programs are conducted in the old fashion classroom setting which has some disadvanta

The Carlin Canyon area is located at the intersection of the westward-flowing r Humboldt River and an unnamed range of hills. These hills trend north-south and are probably a northern extension of the Pinyon Range. In the vicinity of the examined area, Mississippian chert-pebble conglomerates (Tonka fm.) are separated by an angular unconformity fro

This research applied microscopic traffic simulation to freeway work zones to further understand the relationship between traffic variables and capacity. There are two distinct forms of capacity depending upon the flow regime: capacity while traffic is free flowing and capacity while traffic is queued. Actual work zones from the Milwaukee freeway s

FHWA’s Research and Technology (R&T) program is largely governed and shaped by Title 23 United States Code (U.S.C.) § 503, which establishes the Highway Research and Development (HRD) Program and Technology and Innovation Deployment Program (TIDP). HRD funds the research and development (R&D) portion of FHWA’s R&T program, while TIDP governs the te

Most state agencies have good practices for monitoring congestion on roadways within their jurisdiction. Many urbanized areas span state boundaries, where incidents, work zones, and congestion often impact neighboring states or municipalities. States with urbanized borders that experience congestion often develop informal communication procedures a
