Numerous public policies have been promulgated on the assumption that telecommunications will be a useful trip reduction instrument. However, many scholars have suggested that the predominant effect of telecommunications may be complementarity — increasing travel. Although short-term,...

The Innovative Corridors Initiative (ICI) Business Model Analysis examines public-private partnerships designed to deploy intelligent transportation systems (ITS) technologies that can improve transportation system management and provide real-time information to users. This study builds on the...

This technical memorandum summarizes the analysis performed to evaluate the cost of the Long-Life Pavement Rehabilitation Strategies (LLPRS) program. This study is part of the effort to develop an Integrated Pavement Strategy Decision Support System to allow engineers to analyze efficient...

This report presents the results of construction, Heavy Vehicle Simulator (HVS) tests, deflection tests, post-HVS forensic testing, and analysis on dowel bar retrofitted (DBR) concrete pavement test sections at Palmdale, California. This project was originally proposed in 2000 by the Caltrans...

In this final progress report, we describe research results from Phase I of a technical/economic study of fossil hydrogen energy systems with CO2 sequestration. This work was performed under NETL Award No. DE-FC26-02NT41623, during the period September 2002 through August 2004. The primary...

This report is the fifth in a series of first-level analysis reports that describe the results of HVS testing on a full-scale experiment being performed at the Richmond Field Station (RFS) to validate Caltrans overlay strategies for the rehabilitation of cracked asphalt concrete. It describes...

Hydrogen offers potential advantages as a future energy carrier, with respect to reduced emissions of greenhouse gases and air pollutants, and enhanced energy supply security. However, the current lack of an extensive hydrogen (H2) infrastructure is often cited as a serious barrier to the...

Prepared for the National Hydrogen Association Annual Hydrogen Conference (NHA 2005), Washington, DC, March 29 - April 1, 2005 Although reliability has not been evaluated for hydrogen energy systems, it is often assessed in other energy sectors. We investigated methods used to assess reliability...

This report is the fourth in a series of first-level analysis reports that describe the results of HVS testing on a fullscale experiment being performed at the Richmond Field Station (RFS) to validate Caltrans overlay strategies for the rehabilitation of cracked asphalt concrete. It describes...

A free-draining, easy-to-use patch material was evaluated in order to determine if it could be successfully used to patch holes and pop-outs in open-graded asphalt pavements. FloMix, an off-the-shelf patching product from Roklin Systems Inc., was modified to produce a free-draining, fast-setting...
