Paperback: $30.51
Prints in 3-5 business days
This document provides guidelines for identifying stream instability problems at highway stream crossings. It is an update of the third edition published in 2001. The HEC-20 manual covers geomorphic... More > and hydraulic factors that affect stream stability and provides a step-by-step analysis procedure for evaluation of stream stability problems. Stream channel classification, stream reconnaissance techniques, and rapid assessment methods for channel stability are covered in detail. Quantitative techniques for channel stability analysis, including degradation analysis, are provided, and channel restoration concepts are introduced. Significant new material in this edition includes chapters on sediment transport concepts and channel stability in gravel bed streams, as well as expanded coverage of channel restoration concepts.< Less
Evaluation of Utah Transit Authority’s Connection Protection System - Final Project Report By U.S. Department of Transportation
Paperback: $22.49

The Utah Transit Authority (UTA) implemented a Connection Protection (CP) system to improve the reliability of transfers from the higher frequency light rail TRAX trains to the lower frequency bus... More > services. The CP system examines the status of TRAX trains and issues a “hold at {station name} until {time}” message to buses waiting at the connecting rail stations via the bus’ onboard Mobile Data Terminal (MDT), if the lateness of train is within a pre-determined threshold (e.g., three minutes). The system was completed and tested in January 2002 prior to the Winter Olympic Games in Salt Lake City. The successful implementation and operation of the CP system has received attention from the Federal Transit Administration (FTA) and the U.S. Department of Transportation (USDOT) Intelligent Transportation System (ITS) Joint Program Office (JPO) to warrant a national evaluation study.< Less
Ultra-High Performance Concrete: A State-of-the-Art Report for the Bridge Community By U.S. Department of Transportation
Paperback: $22.94
Prints in 3-5 business days
Ultra-high performance concrete (UHPC) is an advanced construction material that affords new opportunities for the future of the highway infrastructure. The Federal Highway Administration has been... More > engaged in research on the optimal uses of UHPC in the highway bridge infrastructure since 2001 through its Bridge of the Future initiative. This report presents the state of the art in UHPC with regard to uses in the highway transportation infrastructure. Compiled from hundreds of references representing research, development, and deployment efforts around the world, this report provides a framework for gaining a deeper understanding of UHPC as well as a platform from which to increase the use of this class of advanced cementitious composite materials. This report will assist stakeholders, including State transportation departments, researchers, and design consultants, to grasp the capabilities of UHPC and thus use the material to address pressing needs in the highway transportation infrastructure.< Less
