Exit Ramp


Book Description

Have you ever wondered how much that guy with the cardboard sign makes? One economics student did and he decided to find out. During the summer of his senior year at college, while earning a B.A. in Economics and Political Science, David P. Spears spent eighty hours undercover as a panhandler. Systematically recording every transaction at the exit ramp, Spears captured a rarely seen picture of how modern urban charity works. This book is the record of his adventures, part economic research, part investigative journalism. Both the numbers and the stories behind the numbers provide answers to the questions we've all been wondering: Who gives more to panhandlers-men or women? What percentage of drivers roll down their windows to donate? And most important of all, how much can a panhandler earn per hour? Get out your bi-weekly pay stub-by the end of this book you'll know if you make more or less than the guy with the cardboard sign.




Off Ramp


Book Description

"We visit discount funeral homes ("Let's say you're dead..."), campgrounds where international bonds are formed ("We are from Netherlands, and we are for two days wonderink, who it is you are"), and storage facilities where America keeps its strangest secrets. We meet the men who drew the comic-book characters (including Wonder Woman) Stuever loved as a child, professional bowlers, waterbed aficionados, and some Texans on "debris drives" in search of pieces of the fallen Columbia shuttle. Finally, we travel to Stuever's hometown of Oklahoma City where the bombing of the Alfred P.Murrah federal building has created a kind of Elsewhere he has never seen before."--BOOK JACKET.




Guidelines for Ramp and Interchange Spacing


Book Description

TRB's National Cooperative Highway Research Program (NCHRP) Report 687: Guidelines for Ramp and Interchange Spacing explores guidelines for ramp and interchange spacing based on design, operations, safety, and signing considerations. The report is designed to help aid the decision-making process when an agency is considering new ramps or interchanges on existing facilities, modifying ramps and interchanges of existing facilities, or when planning and designing new highway and interchange facilities. The guidelines also offer standardized definitions measuring ramp and interchange spacing, which have varied in previous design guides. A final report documenting the full research effort related to the development of NCHRP Report 687 was published as NCHRP Web-Only Document 169--




Traffic Control Systems Handbook


Book Description

This handbook, which was developed in recognition of the need for the compilation and dissemination of information on advanced traffic control systems, presents the basic principles for the planning, design, and implementation of such systems for urban streets and freeways. The presentation concept and organization of this handbook is developed from the viewpoint of systems engineering. Traffic control studies are described, and traffic control and surveillance concepts are reviewed. Hardware components are outlined, and computer concepts, and communication concepts are stated. Local and central controllers are described, as well as display, television and driver information systems. Available systems technology and candidate system definition, evaluation and implementation are also covered. The management of traffic control systems is discussed.
