Summary

This document is the May/June 2006 issue of *Public Roads*, a bimonthly publication by the Federal Highway Administration (FHWA) Office of Research, Development, and Technology. It is not a single research paper but a collection of articles addressing current federal highway policies, programs, and technological developments. The issue highlights three primary areas of focus: safety for an aging population, the evolution of advanced research funding, and the application of high-tech solutions to freight efficiency. The first major article, "Road Users Can Grow Old Gracefully—With Some Help," addresses the challenge of maintaining safe mobility for the growing U.S. population aged 65 and older. The authors note that while older drivers have lower crash involvement rates per 1,000 licensed drivers compared to the general population, their fatality rates per mile driven are comparable to those of young adults due to increased frailty. The article details specific age-related declines in vision, musculoskeletal function, and cognition, such as reduced peripheral vision, slower reaction times, and diminished working memory. It proposes infrastructure countermeasures, including enlarging roadway signs, using retroreflective pavement markings to improve curve detection, avoiding skewed intersection designs, and implementing redundant street signs to aid memory. For pedestrians, the article recommends adjusting traffic signal timing to accommodate slower walking speeds (0.9 meters per second) and installing median refuges and leading pedestrian intervals to enhance safety. The second article, "The Evolution of Advanced Research," outlines FHWA’s strategy for pursuing high-risk, high-payoff technologies under the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU). This legislation authorized a $14 million annual increase in funding for exploratory advanced research. The article distinguishes between basic, advanced, and applied research, emphasizing that advanced research focuses on multidisciplinary, high-risk innovations with the potential for significant breakthroughs. Examples of such research include nanotechnology applications for pavement materials and the installation of fiber-optic sensors in steel rebar to create "smart" bridges capable of nondestructively diagnosing damage and counting traffic. The third featured article, "A High-Tech Route for Freight Efficiency," discusses the use of intelligent transportation systems to mitigate truck congestion. It highlights the Electronic Freight Management (EFM) program, a USDOT-sponsored initiative that partners with industry and government agencies to improve the efficiency, safety, and security of goods movement. The EFM program aims to demonstrate a common message set for the electronic transfer of shipment information between supply chain partners in real time, addressing the growing challenge of freight volume and capacity constraints. Collectively, these articles illustrate FHWA’s dual focus on adapting infrastructure to demographic shifts and leveraging advanced research and information technology to enhance system efficiency and safety. The issue underscores that infrastructure improvements for older road users often benefit all users, while advanced research investments aim to secure long-term technological advantages for the nation’s transportation network.
