Imagine a unit being transformed from Code 4 (C4) (not combat ready) to Code 1 (C1) (fully combat ready) in only 152 days and then successfully executing more than 1,400 combat engineer missions in an urban environment in the span of a one-year deployment. A unit engaged by insurgent forces more than 50 times, yet never wavering in the face of the inherent dangers of combat. A unit whose Soldiers were awarded 42 Bronze Stars, 22 Purple Hearts, and 12 Army Commendation Medals for Valor and nominated for the Meritorious Unit Citation. Sounds like Audie Murphy s unit in World War II, doesn t it? Well, it isn t. This is the story of the 458th Engineer Battalion (Corps) (Wheeled), United States Army Reserve, and how its Citizen-Soldiers provided full spectrum engineer support to the 1st Cavalry Division in the urban environment of Baghdad, Iraq, during Operation Iraqi Freedom. The purpose of this article is to share information with the Engineer Regiment to help guide other engineer units in their preparations for conducting operations in an urban environment in support of the Global War on Terrorism., Published in Engineer p11-14 Jul-Sep 2005.

Some of the data are based on samples and are subject to sampling variability.

Several high profile incidents have focused attention on "tarmac delays" that resulted in air travelers spending long periods of time aboard aircraft waiting to either take off or move to a gate after landing. Taxi-time data collected by the Bureau of Transportation Statistics (BTS) for the year 2007 shows: • Both outbound and inbound taxi times increased noticeably in 2007 and surpassed the previous peak reached in 2000; • 93 percent of flights left the ground within 30 minutes of gate departure, compared to 96 percent in 1995; • Extended taxi times in excess of 2 hours, which occur infrequently, increased in recent years but have not reached the levels experienced in the 1999 to 2000 period; • The longest taxi-out times occurred during the summer; and, • Although flight volumes impact taxiing times, other factors also come into play.

The safety of the traveling public is the number one concern of the U.S. Department of Transportation. Although progress has been made in reducing fatalities, roughly 94 percent of transportation fatalities arose from motor vehicle crashes. Injuries from crashes are a major U.S. public health issue. The U.S. transportation system is an extensive, interrelated public and private network of roads, airports, railroads, transit routes, waterways, terminals, ports, and pipelines. Millions of people and businesses rely on this expanding system to get to work, conduct business, ship goods within the United States and abroad and travel on vacations. The transportation system links regions and connects urban and rural areas. The U.S. transportation system makes possible a high degree of personal accessibility and freight activity. The data in this section show growth in travel and freight shipments over time. Factors influencing this growth include vehicle availability, travel costs, population, congestion, the economy, and consumer income. Transportation is a major sector of the U.S. economy. It moves people and goods, employs millions of workers, generates revenue, and consumes resources and services produced by other sectors of the economy. In 2009, transportation related goods and services contributed $1.2 trillion to the $14.1 trillion U.S. Gross Domestic Product. While transportation enhances the quality of our lives, it also generates environmental impacts that can lead to human health problems and environmental damage. Overall, most transportation air emissions in the United States, such as particulates, have declined since 1980 despite significant increases in U.S. population, Gross Domestic Product, and vehicle-miles traveled. However, carbon dioxide emissions from transportation fuel use rose steadily until 2007 before decreasing in 2008. Statistics published in this Pocket Guide to Transportation come from many different sources. Some statistics are based on samp
