Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a study to determine passenger car equivalents (PCEs) of trucks and other vehicles on urban freeways. Field data collection used the Traffic Evaluator System (TES). Samples of weaving, merge, diverge, and basic freeway sections were studied in Houston, Dallas and Atlanta. Detailed vehicle classification, headway, speed, and spacing were developed for over 287,000 vehicles.

Book excerpt: The objective of this work was to determine the passenger car equivalent value for fourteen different vehicle types under varying traffic and roadway geometry conditions. This was accomplished by analyzing field data collected in several states on both two-lane and four-lane highways. Data included headways, speeds and travel time by vehicle type, traffic volume condition, and roadway section type. An analytical model was developed to estimate passenger car equivalent values based upon speed distributions, traffic volume, and vehicle type. The calibrated model was used to estimate passenger car equivalent values for fourteen vehicle types under the specified typical conditions for two-lane and four-lane rural highways.

This book was released on 2010 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The significant impact Heavy Vehicles (HV) have on freeway operations has been identified since the first edition of the Highway Capacity Manual (HCM). The method of incorporating their impact in freeway capacity calculations has changed through the years. The HCM 2000 used Passenger Car Equivalent (PCE) values and percent of trucks/buses and Recreational Vehicles (RV) to account for HV effect on capacity. However PCE values in the most recent HCM edition rely on a limited field database and extensive simulation runs based on this information; they were calibrated on s̀teady-flow' traffic operations. The objective of this effort was to indentify and quantify HV characteristics that have an impact of freeway throughput at various congestion levels on level, urban freeways using 1.2 million individual vehicle observations, with an emphasis on operations at LOS E and F. It was desired to use the products of this effort as recommended inputs for future simulation runs of congested freeway flow conditions. Passenger Car (PC) and HV headways were found to increase with HV presence in the traffic stream. A similar pattern was found for the PCE factor. The PCE value, under congested conditions and more than 9% HV presence, was found to be 1.76, which is higher than the HCM 2000-recommended value of 1.5 for level freeway sections. Also, passenger car was found to have the effect of more than 1 PC at congested condition with high HV presence.

This book was released on 2014-04-03 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1950, the Highway Capacity Manual has been a standard used in the planning, design, analysis, and operation of virtually any highway traffic facility in the United States. It has also been widely used abroad, and has spurred the development of similar manuals in other countries. The twin concepts of capacity and level of service have been developed in the manual, and methodologies have been presented that allow highway traffic facilities to be designed on a common basis, and allow for the analysis of operational quality under various traffic demand scenarios. The manual also addresses related pedestrian, bicycle, and transit issues. This book details the fundamental development of the concepts of capacity and level of service, and of the specific methodologies developed to describe them over a wide range of facility types. The book is comprised of two volumes. Volume 1 (this book) focuses on the development of basic principles, and their application to uninterrupted flow facilities: freeways, multilane highways, and two-lane highways. Weaving, merging, and diverging segments on freeways and multilane highways are also discussed in detail. Volume 2 focuses on interrupted flow facilities: signalized and unsignalized intersections, urban streets and arterials. It is intended to help users of the manual understand how concepts, approaches, and specific methodologies were developed, and to understand the underlying principles that each embodies. It is also intended to act as a basic reference for current and future researchers who will continue to develop new and improved capacity analysis methodologies for many years to come.
