Texas Transportation Institute: Traffic congestion creates $78 billion drain

Traffic congestion continues to worsen in American cities of all sizes, creating a $78 billion annual drain on the U.S. economy in the form of 4.2 billion lost hours and 2.9 billion gallons of wasted fuel — that’s 105 million weeks of vacation and 58 fully loaded supertankers.

These are among the key findings of the Texas Transportation Institute’s 2007 Urban Mobility Report. Improvements to the methodology used to measure congestion nationwide have produced the most detailed picture yet of a problem that is growing worse in all 437 of the nation’s urban areas. The current report is based on 2005 figures, the most recent year for which complete data was available.

“There is no ‘magic’ technology or solution on the horizon because there is no single cause of congestion,” noted study co-author Tim Lomax, a research engineer at TTI. “The good news is that there are multiple strategies involving traffic operations and public transit available right now that if applied together, can lessen this problem.”

The 2007 mobility report notes that congestion causes the average peak period traveler to spend an extra 38 hours of travel time and consume an additional 26 gallons of fuel, amounting to a cost of $710 per traveler. Along with expanding the estimates of the effect of congestion to all 437 U.S. urban areas, the study provides detailed information for 85 specific urban areas.

The report also focuses on the problems presented by “irregular events” — crashes, stalled vehicles, work zones, weather problems and special events — that cause unreliable travel times and contribute significantly to the overall congestion problem. Worsening congestion, the study notes, is reflected in several ways:

  • Trips take longer

  • Congestion affects more of the day

  • Congestion affects weekend travel and rural areas

  • Congestion affects more personal trips and freight shipments

  • Trip travel times increasingly are unreliable

  • Researchers spent two years revising the methodology using additional sources of traffic information, providing more — and higher quality — data on which to base the current study.

  • The report identifies multiple solutions to the congestion problem that, researchers say, must be used together to be effective. These include:

  • Get as much service as possible from existing infrastructure

  • Add road and transit system capacity in critical corridors

  • Relieve chokepoints

  • Change usage patterns

  • Provide choices

  • Diversify the development patterns

  • Keep expectations realistic

  • “Congestion is a far more complex problem than is apparent at first glance,” Lomax said. “The better the data we use to define the problem, the more successful we will be in addressing its root causes.”

Cemex and Polaris Minerals Corp. on Sept. 26 entered into a long-term supply and distribution agreement for marine transported construction aggregates in the states of California, Oregon, and Washington.

For this three-state area, the parties have agreed that Cemex will be the exclusive marketer for Polaris, and Polaris will be the exclusive supplier to Cemex of marine transported construction aggregates for the company’s internal use and for sales by it to third parties.

Polaris has already commenced sand and gravel shipments from the Orca Quarry to the two existing Cemex terminals in San Francisco Bay. In addition, the two companies have entered into an alliance for the development of future construction aggregates import terminals in the same territory.

Included in the strategic alliance is an expectation that Polaris will develop its 70-percent-owned Eagle Rock Quarry at a time to be determined by market demand. The parties have agreed to cooperate in the pursuit of markets and terminal capacity for Eagle Rock crushed granite products. The existing Polaris construction aggregate supply and distribution agreement covering the four northern California counties of Marin, Sonoma, Mendocino, and Napa is unaffected by this alliance.

Allstone Quarry Products makes Guinness Book of World Records

Most Canadians spell it inukshuk. The government of Nunavut says it’s inuksuk. No matter how you spell it, Joe Melo owns the largest one in the world and the Guinness Book of World Records is ready to honor that achievement.

At 11.9 meters high, Melo’s inuksuk beats the nearest competition, the 2010 Olympic mascot, by almost 3 meters. Built from 11 pieces of solid granite, the giant statue weighs 82 tons. The arms alone — made of a single slab of granite — are a half-meter thick and span more than 8 meters across.

The statue was assembled by crane and is held together by gravity alone, with only the inuksuk’s feet imbedded in solid concrete.

Melo, owner of Allstone Quarry Products near Shomberg, extracted the granite from his quarry in Big Wood Township located about 40 minutes south of Sudbury.

The statue was officially submitted to the Guinness organization Sept. 13 as a certified structural engineer, a certified surveyor and other witnesses made a full report on the monument’s vital statistics.

Melo, who supplies some of the biggest chunks of rock in the province, says he never intended to beat the world’s record. He built the structure about five years ago and says he wasn’t aware that the inuksuk was the world’s tallest until several marketing companies brought the fact to his attention.

Cemex Confirms Plans to Sell Some Assets to CRH

Mexican cement company Cemex on Sept. 17 confirmed that it is in talks to sell some of its U.S. and European assets to CRH, an Ireland-based international building materials group.

“The total value of the transactions could range from $3.5 billion to $4.5 billion,” Cemex said in a statement, confirming an earlier statement issued by CRH.

The assets under negotiation include those operations in Florida and Arizona that the U.S. Department of Justice has required Cemex to sell as a result of its acquisition of Australia’s Rinker earlier this year, according to a Cemex statement.

Cemex is also discussing the possibility of selling a number of other assets in the U.S., including its concrete pipe business, its materials and concrete products operations in the Pacific Northwest, Utah, Wyoming, Nebraska, New Mexico, and El Paso, Texas, its the aggregates operations in Kentucky, its cement plants in Wampum, Pa., and Fairborn, Ohio, and its gypsum wallboard distribution business in Florida.

In Europe, the assets under negotiation include the San Feliu cement plant in Catalonia, Spain and Cemex’s ready-mix concrete and aggregates assets in Austria and Hungary, the Cemex statement said.

 Citigroup, Merrill Lynch and Morgan Stanley are acting as financial advisors, Cemex said.

Open House at Ostrander Quarry in Ohio

A public open house was held at the Shelly Materials Ostrander Quarry on Aug. 25, with more than 550 neighbors, customers, and employees in attendance.

A blast that provided the operation with more than 15,000 tons of shot rock was set off during the open house to show what is entailed in the procedure.

Other activities included bus trips into the quarry, booths set up by Shelly Materials, Ohio Geological Survey, Dyno Nobel, and Sauls Seismic., as well as obstacle courses, equipment displays, and rock painting.

The Ostrander Quarry produces more than 1,500,000 tons per year of limestone with No. 304 and No. 57 as the operation’s primary products. These products are mostly used for concrete, asphalt, and as a base material for foundations of parking lots, buildings, schools, hospitals, roadways, and sidewalks.

The ShelleyCo.’s Ostrander Quarry set off a blast at its Aug. 25 open house so attendees would better understand what it entails. The blast provided the operation with about 15,000 tons of shot rock. A clown paints a young girl’s face at the open house, which was held to help with community relations efforts between the aggregates operation and the community.

Market Situation

by Bill Watkins

Due to the recent consolidation in the construction materials sector, all of the companies have been combined into one index, which more accurately reflects industry performance given the vertical integration of most large producers. In general, the industry index continues to outperform the broad universe. Acquisition premiums remain embedded in many stock prices, which continue to provide some pricing support. In addition, the more diversified and integrated businesses continue to report relatively strong earnings, which bode well for their respective share prices. Overall, long-term industry fundamentals remain positive for construction materials producers.

Production

U.S. Aggregate Production Down in 2007

Crushed stone and sand and gravel production dipped down in the second-quarter of this year.

by Jason Christopher Willett, Wallace P. Bolen, and Marc A. Angulo

Editor’s note: The U.S. Geological Survey (USGS) released its quarterly report on the amount of aggregate produced and shipped in late September. A detailed report from the government agency follows.

An estimated 389 million metric tons of crushed stone was produced and shipped for consumption in the United States during the second quarter of 2007, a decrease of 14.9 percent compared with the same period of 2006. The estimated output of crushed stone produced for consumption during the first six months of 2007 was 643 metric tons, a 17.8-percent decrease compared with the same period of 2006.

The estimated U.S. output of construction sand and gravel produced and shipped for consumption in the second quarter of 2007 was 292 metric tons, a decrease of 14.0 percent compared with that of the same period of 2006. The estimated output of construction sand and gravel produced for consumption in the first six months of 2007 was 471 metric tons, a 15.9-percent decrease compared with the same period of 2006.

An estimated 681 metric tons of total aggregates was produced and shipped for consumption in the United States during the second quarter of 2007, a decrease of 14.2 percent compared with that of the same period of 2006. The estimated output of aggregates produced for consumption during the first six months of 2007 was 1.11 billion metric tons, a 16.9-percent decrease compared with that of the same period of 2006.

Portland cement consumption

The estimated portland cement consumption decreased by 8.7 percent during the second quarter of 2007 and decreased by 11.5 percent during the first six months of 2007, compared with that of the same period of 2006. This information is a product of the USGS monthly survey of U.S. cement producers.

The production-for-consumption estimates for crushed stone, construction sand and gravel, and aggregates, are generated independently for each state and each geographic division, and the 48 conterminous states, which are treated as separate statistical sample areas. Therefore, some differences may exist between the total for a division and the sum of the state totals that are part of the same geographic division.

Similarly, differences may exist between the estimations of total aggregates and estimations done separately for crushed stone and construction sand and gravel for a specific statistical area. The information from the USGS quarterly survey on domestic production of crushed stone, construction sand and gravel, and aggregates has become a significant indicator of construction activity at the national, regional, and state level.

This survey is a sample survey that generates production-for-consumption estimates by quarters, based on information reported voluntarily by a limited number of producing companies.

Occasionally, the number of companies reporting in an area varies from quarter to quarter, or previously reported data by some companies are revised. As a result of such changes in the size or the composition of the statistical sample, the estimated quantities for prior quarters are recalculated. The latest release of the quarterly Mineral Industry Surveys contains the most recent estimated totals and percentage changes and supersedes previously published similar information.

Estimated aggregate sales

The estimated crushed stone sold or used in the United States during the second quarter of 2007 decreased in eight of the nine geographic divisions. The largest decreases were recorded in the West South Central (24.8 percent), South Atlantic (24.2 percent), and West North Central (20.4 percent) divisions. The only increase in the production of crushed stone was recorded in the Mountain (5.1 percent) division.

The leading geographic divisions in the production of crushed stone sold or used during the second quarter of 2007 were the South Atlantic with 91.3 metric tons, or 23.5 percent of the U.S. total, followed by the East North Central with 72.4 metric tons, or 18.6 percent, and the Middle Atlantic with 50.6 metric tons, or 13.0 percent.

The estimated construction sand and gravel sold or used in the United States in the second quarter of 2007 decreased in eight of nine geographic divisions. The largest decreases were recorded in West North Central (24.3 percent), the South Atlantic (21.3 percent), and the East North Central (19.5 percent) divisions. The only increase in the production of construction sand and gravel was recorded in the New England (7.8 percent) division.

The leading geographic divisions for the total amount of construction sand and gravel sold or used in the second quarter of 2007 were the Mountain with 74.1 metric tons, or 25.4 percent of the U.S. total, followed by the Pacific with 53.0 metric tons, or 18.2 percent, and the East North Central with 50.3 metric tons, or 17.2 percent.

The estimated U.S. output of aggregates sold or used in the second quarter of 2007 decreased in all of the nine geographic divisions. The largest decreases were recorded in the South Atlantic (24.0 percent), the West South Central (23.3 percent), and the West North Central (21.7 percent) divisions.

The leading geographic divisions for the total amount of aggregates sold or used in the second quarter of 2007 were the East North Central with 124 metric tons, or 18.2 percent of the U.S. total, followed by the South Atlantic with 111 metric tons or 16.3 percent, and the Mountain with 92.5 metric tons, or 13.6 percent.

The estimated totals by quarters for the geographic divisions do not include Alaska and Hawaii.

The estimated production-for-consumption of crushed stone in the second quarter of 2007 decreased in 38 of the 47 states that were estimated, with the largest percentage decreases occurring in South Dakota (55.1 percent), Wyoming (42.0 percent), Nebraska (40.5 percent), South Carolina (32.4 percent), and North Carolina (31.9 percent). The five leading states, in descending order of production, in the production-for-consumption of crushed stone during the second quarter of 2007 were Pennsylvania, Texas, Florida, Georgia, and Illinois. Their combined total production-for-consumption represented 30.5 percent of the U.S. total.

The production-for-consumption of construction sand and gravel decreased in 35 of the 46 states that were estimated, with the largest decreases occurring in Arkansas (68.7 percent), Nevada (47.6 percent), Minnesota (38.4 percent), Florida (33.9 percent), and South Dakota (33.2 percent). The five leading states, in descending order of production, in the production-for-consumption of construction sand and gravel during the second quarter of 2007 were California, Arizona, Texas, Michigan, and Washington. Their combined total production-for-consumption represented 34.6 percent of the U.S. total.

The production-for-consumption of total aggregates in the second quarter of 2007 decreased in 40 of the 46 states that were estimated, with the largest decreases occurring in South Dakota (49.6 percent), Nebraska (38.5 percent), Wyoming (35.6 percent), Nevada (33.0 percent), and North Carolina (30.8 percent). The five leading states, in descending order of production, in the production-for-consumption of aggregates during the second quarter of 2007 were California, Texas, Pennsylvania, Florida, and Ohio. Their combined total production-for-consumption represented 26.9 percent of the U.S. total.
