Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.

Book Description
The objective of this study was to identify means by which improved traffic control can improve traffic safety at work zones. The accident data base was derived from the coded information stored in the computerized data bank of the Ohio Department of Highway Safety. Coding errors and unreported accidents were recognized as limitations of the data base. Statistical analysis of statewide aggregate data failed to identify cause and effect relationships between accident characteristics and traffic control. The study was expanded to include the review of individual accident reports at nine construction sites. This approach proved very effective. The accident reports which always included a sketch and a description of the event often indicated that specific traffic control procedures and standards needed to be improved. It has become clear to the researchers that certain types of accidents at a given work zone can suggest specific problems with traffic control plans and/or with the implementation of the plans. Monitoring work zone accidents as they happen is of course the best way to recognize and eliminate problems.

Book Description
Volume I illustrates many of the typical worksites describing the most common conditions encountered. The information provided can be used to supplement local, state, and national standards. The topics include, among others: Public information, regulatory control, special traffic provisions, protection of pedestrians, flagging, temporary traffic signals, and nighttime procedures. Volume II is intended primarily for use by job site supervisors. It addresses the most common situations, problems and solutions that supervisors might be faced with. The topics include, among others: Emergency work moving operations, temporary traffic control devices, placing devices, temporary removal of signs, and pedestrian needs.

Book Description
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. For the covering abstract of this Conference see IRRD abstract number 853851.
