Implementation of Database for TxDOT ARRA Projects

Report discussing projects initiated under the American Recovery and Reinvestment Act of 2009 (ARRA), a fiscal stimulus package signed by President Obama on March 6, 2009. State agencies like the Texas Department of Transportation (TxDOT) who received ARRA funds had to report, on a monthly basis, various data on each project in the ARRA program, including staff numbers, hours worked, and payroll. TxDOT asked the Center for Transportation Research (CTR) to identify and isolate specific elements of the 0-6592 database that TxDOT's Construction Division (CST) can implement into an existing TxDot database. This report describes the implementation of the database and procedures for updating it.

Operational and vehicular strategies for reducing fuel consumption and Green House Gas emissions from trucking

"Reducing fuel consumption and greenhouse gas emissions is becoming increasingly important in the United States, and new legislation can be expected in the near future that will affect trucks either directly or indirectly. This work is a qualitative examination of operational strategies for reducing fuel consumption from freight trucking, and also compares them with vehicular strategies. A focus is placed on who implements, benefits from, and pays for each strategy, and what type of trucking each strategy is applicable to."
