Available in PDF, EPUB and Kindle. Book excerpt: At the close of the year 1900, motor vehicle registrations throughout the United States totaled 8000. These vehicles rode on unpaved and often dusty country roads. The only problem of traffic was an occasional pedestrian or a frightened horse or cow frenzied by the roar of this new creature. Today more than 82,000,000 registrations, representing 50% of the world's automobiles, are recorded in this country. In 1963 these vehicles traveled 798 billion miles over newly constructed modern highways, expressways, freeways, quickways, and thru ways, as well as improved rural and urban roads and streets. Out of all this has sprung the traffic engineer. Today's modern roadway is an engineering structure which has been developed through sound principles of design with provisions for safety and efficiency. An example of this safety factor can be found by the exacting specifications for cross sections, grades, roadside control, medians, and other design features. For many years, the responsi bility for controlling traffic fell naturally into the domain of the police. However, as traffic increased, many problems developed which were beyond the scope of normal police work. Since the highway system is an engineering structure which requires an engi neering approach to appraise operating problems and engineering techniques to solve them, the traffic engineer came into being.

Book excerpt: The handbook, in its treatment of signs, pavement markings and signals, presents typical values or ranges of values used for implementing traffic control measures, as well as providing examples of contract plan sheets, specifications and work orders. With respect to signs, consideration is given to materials, equipment, installation, maintenance, vandalism, etc. The section on pavement markings includes materials, methods of application and application operations. Traffic signal design, operation, equipment, and maintenance are discussed, as are various types of signal systems.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes and evaluates the important findings from the literature review of the studies on work zone speed control techniques. The following treatments are included in this report: 1) flagging, 2) lane width reduction, 3) law enforcement, 4) changeable message signs (CMS), 5) rumble strips, and 6) flashing beacons. The effects of the speed control treatments on speed and traffic flow are evaluated based on: A) experiences with treatment, B) effects of treatment on speed, C) effectiveness of treatment, and D) comments about treatment. A brief description of the conditions under which the treatments were applied is provided, and the speed reduction effects of each technique are discussed. A reference matrix was prepared to identify publications related to each type of speed reduction treatment used in work zones.

This book was released on 1990 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Safety at construction and maintenance zones is now considered as one of the major concerns of traffic and highway engineers, particularly in urban areas where the installation of work zones significantly affect the flow of traffic . This issue is getting more important as greater emphasis is placed on maintenance and rehabilitation work rather than on new construction, resulting in the proliferation of work zones in the nation's highways. Preliminary analysis of accident data at urban workzones in Virginia indicates that accident rates tend to be significantly higher when work zones coupled with the expected increase in traffic volume will result in significant increase in accident rates, unless effective measures are taken to increase safety at these work zones. The identification of effective safety counter measures at urban work zones, however, requires a clear understanding of work zone accident characteristics and knowledge of the effectiveness of different traffic control devices commonly used. A study was therefore conducted to identify the predominant accident characteristics in urban work zones in Virginia and to evaluate the effectiveness of different traffic control devices in reducing the increase in accident rates during periods of work zone activities. This paper presents the results of statistical analyses of accident data for different work zones and the predominant accident characteristics identified from these analyses. While significant increase in accident rates were observed, there was no significant difference observed in type and severity of accidents.
