The article explores the ways by which three communities in the U.S. have built roads and manage traffic flow. It describes the custom traffic-modeling tool developed by Iowa State University's Institute for Transportation (InTrans) for West Des Moines Public Works in Iowa. The use of inSync from Rhythm Engineering for traffic flow management in Lenexa, Kansas is discussed. The queue jumper technology is integrated into signalized intersections where bus traffic is heaviest in the city of Chandler, Arizona.

Presents question and answer advisory about operations at motor vehicle accidents. Main components of operating guideline; Need for firefighters to wear their reflective traffic vest; Deployment of law enforcers in place early during auto accidents to assist with traffic flow and crew safety.

Focuses on the high-occupancy toll (HOT) lanes, an option to relieve traffic congestion in the U.S. by restricting the use of some freeway lanes to those drivers who pay to use them. Assessment of tolls for HOT lanes; Background on the emergence of the HOT lanes concept; Implementation of the San Diego Association of Governments projects.

The article focuses on the use the traffic-sensor post (TSP), a wireless, solar-powered sensor array in monitoring traffic flow. The author says that TSP offers a more accurate, inexpensive, and easy-to-install approach. TSP may share data of vehicle location with nearby intersections, communicate to radio emergency requests, and take commands from a traffic-control center. TSP uses the Cap Pad, passive-infrared (PIR) sensors, and pneumatic tubes. The author compares the accuracy of Cap Pad and weight-in-motion (WIM) sensor applications.

The article reports that engineers at Traffic.com Inc. had devised a way to save fuel by monitoring traffic flows with sensors stationed along roadsides. The company opted for solar panels, which can provide the 5W requirements during the day and charge batteries that last through the night. Traffic.com has installed more than 3,000 solar-powered traffic sensors, with another 10,000 or so scheduled. That underscores the success of solar power, which has been growing at double-digit rates for the past few years. The company's finely-focused application also points up solar's struggle to become a viable competitor in the power arena. INSET: Wind Energy Catches Updraft.

Discusses the installation of the Intelligent Transportation System (ITS) in Dallas which will assist the Texas Department of Transportation (DOT) in traffic management. Use of video cameras to observe roadways; Transference of data at automated teller machines (ATM); Speculation that traffic information will eventually be made available to commuters via the Internet.

The article reports on the views of the readers of American City & County e-mail newsletter on the solution to traffic congestion in the U.S. Reason Foundation predicted that more lane-miles of capacity would have to be added to the nation's freeways. According to Tim Keenan of Cypress, expanded transit options is the only solution to get people around and avoid gridlock. Mayor John Hieftje of Michigan says travel options must be increased through efficient and cost-effective mass transit.

Focuses on plans of state and local traffic agencies to remedy highway congestion in the U.S. Statement from Monique Bond of the Chicago Office of Emergency Management about the effect of stranded vehicles on the traffic flow; Approach used by the Pennsylvania Department of Transportation to ease the traffic; Tactics used by the Georgia Regional Transportation Authority to clear roads.

Reports on the Crossrail project to link east and west London. Plans to drill a twin-bore tunnel capable of carrying mainline trains at 60-100 mph from Paddington to Liverpool Street; Obstacles in the form of utility networks, building foundations, and tube lines; Merging of existing paths with the underground corridors to avoid purchase of large land for tracks; Use of links to provide a major strategic route to reduce congestion on the roads and on existing rail lines.

The article reports on how signal synchronization can help mitigate traffic problems in California. According to the "County News" newsletter, the problems originate on the highways. It mentions a microprocessor called a Universal Time Base Unit installed at each intersection that synchronizes lights based on an atomic clock.

The article offers a look at the findings of the 2010 Urban Mobility Report which forecasts the growth of traffic congestion in most urban areas in the U.S. Tim Lomax, researcher of the report, published by the Texas Transportation Institute at Texas A&M University, explains the findings of the comprehensive national congestion measurement. The report highlights some of the effects of the traffic problems in the country. It also features several strategies for reducing traffic congestion.

The article focuses on a research concentrating the road train concept supported by technology firm Ricardo PLC and carmaker Volvo AB. It notes that this idea could improve traffic flow, reduce accidents and improve fuel consumption. Eric Coelingh of Volvo AB states that this type of autonomous driving does not require any investment in infrastructure.

The article reports on the results of a study conducted the Australian Bureau of Transport and Regional Economics which reveals that the overall cost of traffic congestion in 2005 across all capital cities was $9.39 billion. This amount includes the impact of extra vehicle costs and longer and less flexible travel times. It is projected that congestion cost could rise to $20.40 billion in 2020.

Deals with the 2004 Urban Mobility Report by the Texas Transportation Institute, which evaluated the congestion problem in U.S. cities. Population in urban areas; Recognition of the need for infrastructure capacity in modes of transportation; Role of the U.S. Congress in the passage of transportation legislation against congestion.

Focuses on the traffic management project at the University of California at Berkeley, designed to send data over a wide area network from sensors in California highways to the California Department of Transportation, where it can be used to accurately predict traffic flows. Project design; Congestion reduction resulting from the diversion of about 5 percent of traffic.

Comments on the Mobility 21, a group which aims to find ways to improve the traffic congestion problems in Los Angeles County, California. Members of the group; Goals of the group; Issues being lobbied by the group in the U.S. Congress.

The article reports on the launching of the Intelligent Vehicle/Highway System projected for the area of Orlando, Florida. Drivers equipped with Oldsmobile Trofoes will get advice from their vehicles though electronic maps, symbolic displays, and synthesized voice. The automobiles will also report their position and status to a traffic management center. Likewise, the said report will also gather traffic flow data for the American Automobile Association's (AAA) database and render traffic advice to drivers.
