Book Description
This 33-mile segment of US Highway 550 has a greater avalanche hazard than aU other Colorado highways combined. A total of 95 avalanche paths intersect the highway with an avalanche hazard of 443. More than 70 encounters between avalanches and vehicle. and six fatalities have occurred since 1950. The objective of this research project is to develop a methodology for calculating the severity of a particular avalanche activity. The project is not intended to develop a "black box" type of computer program for avalanche forecasting. Instead, it is intending to investigate parameters that may be important in forecasting on Highway 550, and to suggest how they may be used to forecast avalanches in the future

Book Description
This report represents the findings of a study that demonstrates the feasibility of estimating link travel time and speed in real-time for rural, mountainous sections of interstate freeway in Colorado using vehicles instrumented with global positioning system (GPS) receivers, serving as probes in traffic streams. The system configuration developed includes a cost-effective, portable GPS deployment unit, communication links to a server PC and an integrated prototype system for vehicle tracking and estimating link travel time statistics. This study was carried out in two phases. The objective of the first phase was to identify a cost-effective means of monitoring traffic within a rural, mountainous stretch of the I-70 freeway. An algorithm was developed to estimate average link speed, travel time and the standard error of estimates to provide user information on the reliability of the estimates based on the probe data. The algorithm was tested for different traffic conditions and geometric characteristics of links. In the second phase of the project, a real-time demonstrational prototype was developed to receive, process and estimate link travel time and speed statistics in real-time. The system was tested off-line and on-line based on field data received from the I-70 corridor. In addition, GPS receivers were deployed using a commercial vanpool service and the system was evaluated further.

Book Description
This report documents the noise measurements taken using a single vehicle on four different pavement surface textures. The pavements were located on US285 southwest of Denver, Colorado. Noise measurements were taken inside the vehicle, 25 ft from the center of the closest driving lane, and near the right rear tire. Skid testing was performed at 40 mph in conformance with the American Society for Testing and Materials procedure E 274 for a ribbed tire. The surface types included longitudinal tined concrete, transverse tined concrete, ground concrete, and an asphalt surface (3/8 in. nominal Stone Mastic Asphalt).

Book Description
This volume grew out of a conference organized by James Alleman and Paul Rappoport, conducted on October 10, 2011 in Jackson Hole, Wyoming, in honor of the work of Lester D. Taylor, whose pioneering work in demand and market analysis has had profound implications on research across a wide spectrum of industries. In his Prologue, Eli M. Noam notes that demand analysis in the information sector must recognize the “public good” characteristics of media products and networks, while taking into account the effects of interdependent user behavior; the strong cross-elasticities in a market; as well as the phenomenon of supply creating its own demand. The second Prologue, by Timothy Tardiff and Daniel Levy, focuses more specifically on Taylor’s body of work, in particular its practical applications and usefulness in analyses of, and practices within, the Information and Communications Technology (ICT) sector (known in Europe and elsewhere as the Telecommunications, Media, and Technology (TMT) sector). The remainder of the book is organized into four parts: Advances in Theory; Empirical Applications; Evidence-Based Policy Applications; and a final Conclusion. The book closes with an Appendix by Sharon Levin and Stanford Levin detailing Taylor’s contributions using bibliometrics. Not only featuring chapters from distinguished scholars in economics, applied sciences, and technology, this volume includes two contributions directly from Lester Taylor, providing unique insight into economics from a lifetime in the field. “What a worthy book! Every applied researcher in communications encounters Lester Taylor’s work. Many empirical exercises in communications can trace their roots to Taylor’s pioneering research and his thoughtful leadership. This book assembles an impressive set of contributors and contributions to honor Taylor. No surprise, the collection extends far and wide into many of the core topics of communications and media markets. The emphasis is where it should be–on important and novel research questions informed by useful data. —Shane Greenstein, Professor of Management and Strategy, Kellogg School of Management, Northwestern University “For more than 40 years, Lester Taylor has been a leader in the application of consumer modeling, econometric techniques and microeconomic data to understand residential and business user behavior in telecommunications markets. During that time, he inspired a cadre of students and colleagues who applied this potent combination to address critical corporate and regulatory issues arising in the telecommunications sector. This volume collects the recent product of many of these same researchers and several other devotees who go beyond empirical analysis of fixed line service by extending Prof. Taylor’s approach to the next wave of services and technologies. These contributions, including two new papers by Prof. Taylor, offer an opportunity for the next generation to learn from his work as it grapples with the pressing issues of consumer demand in the rapidly evolving digital economy.” — Glenn Woroch, Adjunct Professor of Economics, University of California, Berkeley
