A new and improved version of the Federal Highway Administration's (FHWA) QuickZone software offers highway agencies and others an even more effective tool for work zone planning. First released in 2002, QuickZone has been used by State and local highway agencies and construction contractors as a work zone delay impact analysis tool. The Microsoft Excel©-based software compares the traffic impacts for work zone mitigation strategies and estimates the costs, traffic delays, and potential backups associated with these impacts. These costs and delays can be estimated for both an average day of work and for the entire life cycle of construction.
Slow Down or Pay Up. That's the message for motorists during National Work Zone Awareness Week (NWZAW) 2005, April 3-9. In 2003, 1,028 people were killed in motor vehicle crashes in work zones and an estimated 41,000 were injured. More than 80 percent of those killed were drivers and passengers.
Across the United States, the use of recycled concrete aggregate (RCA) in the highway infrastructure is reducing waste, cutting costs, and providing durable new roads. Advanced transportation uses of RCA are highlighted in a new Federal Highway Administration (FHWA) report, Transportation Applications of Recycled Concrete Aggregate. The report details the results of a year-long review of RCA use and practices in five States-California, Michigan, Minnesota, Texas, and Virginia (see April 2004 Focus).
Europe's use of innovative quiet pavement technologies to reduce highway noise was the focus of an international scanning tour in the spring of 2004. Jointly sponsored by the Federal Highway Administration (FHWA), American Association of State Highway and Transportation Officials (AASHTO), and the Transportation Research Board/National Cooperative Highway Research Program, the scanning tour team consisted of representatives from FHWA, State transportation agencies, private industry, and academia.
