The United States and many other advanced industrial countries are concerned about the slow down in productivity growth since the early 1970s. Recent discussions in the literature have emphasized inadequate growth of infrastructure capital as a cause of the slow down in productivity at the aggregate and industry levels. The level of aggregation use

Connection plates cross frame diaphragms not rigidly attached to tension flanges can develop fatigue cracking in the unstiffened web gap due to the out-of-plane distortion. This report investigates repair procedures for fatigue damage in the web gap of steel highway bridges. The procedures investigated include drilling holes at crack tips, flame-cu

This report addresses a primary dilemma of the transportation planning community, namely, how to evaluate and compare urban passenger transportation projects regardless of mode. After identifying the full-cost approach as an effective tool for undertaking such comparisons, this report describes MODECOST, a full-cost evaluation model developed by th

Using a full-cost approach, we evaluated the different transportation improvement alternatives (developed by Rust Lichliter/Jameson) available for the Northeast (IH-35) corridor in San Antonio, Texas. Through MODECOST- a computer model based on the full-cost analysis concept- we found that the current facility cannot meet future traffic demands. As

This research study investigated guide signing practices used around the state and the rest of the nation for multilane exits. In particular, the research focused on signing for multilane exits with optional lanes. Photographs were taken of guide signing at multilane interchanges in the cities of San Antonio, Houston, Dallas, and Fort Worth, Texas.
