This synthesis will be of interest to maintenance engineers, traffic engineers, and others interested in the management aspects of maintaining urban freeways. Information is provided on techniques and procedures used by agencies to improve and speed up maintenance procedures, schedule work, and coordinate freeway lane closures. Maintenance of aging urban freeways is difficult because of the high volumes of traffic on these facilities. This report of the Transportation Research Board describes techniques and procedures that highway agencies are using, such as reducing work time and scheduling work for off-peak periods, to minimize traffic delays while freeway maintenance is performed.
This synthesis will be of interest to state and local traffic engineers, transportation planners, transit operators, law enforcement officials, public information agencies, and others responsible for the transportation elements of freeway corridors. Information is provided on the policies and procedures for freeway corridor management, and descriptions of a number of techniques and practices are presented. Traffic growth and increasing congestion on urban freeways require a comprehensive approach toward managing the complex elements of freeway operations. This report of the Transportation Research Board provides information on freeway corridor management strategies, the components of management, examples of effective applications of the strategies, and benefits of freeway corridor management. The management techniques that are discussed include freeway surveillance and control; corridor street surveillance and control; high-occupancy vehicle facilities and incentives; police enforcement and traffic control; hazardous material and other truck traffic restrictions; alternative route planning; motorist assistance patrols; motorist information techniques; and traffic management for recurrent congestion, for incidents, for special events, and for work zones.
Experience of the past decade confirms that the solution to infrastructure problems is not merely to expand capacity by making new investments. Much more systematic changes must be undertaken if service delivery is to attain the standards necessary to improve quality of life and allow economic output to expand more rapidly. This paper identifies several broad areas for reform and recommends a series of actions to attain effective service delivery. (Adapté du résumé de l'auteur).
This synthesis will be of interest to traffic engineers, maintenance managers, sign shop supervisors, and others interested in the maintenance of street and highway signs. Detailed information is presented on the current practices of state and local governments in managing the maintenance of street and highway signs within their jurisdictions. The maintenance of street and highway signs is viewed as a means for improving the effectiveness of a signing system. This report of the Transportation Research Board describes the maintenance practices of several state and local highway agencies along with the rationale for those practices. It covers inspection, refurbishing, and replacement practices, along with information on equipment and personnel requirements.
This publication, which describes reconstruction experiences, gives case studies which document the varied projects, and gives specific ideas for the management of major highway reconstruction. This report also discusses the use of incentive/disincentive provisions for early contract completion. Ways to expedite expressway and bridge rehabilitation are summarized, and a policy statememt is provided on the application of traffic management actions. Abstracts and summaries are given of recently published literature in the area of corridor traffic management for temporary flow disruptions.
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.
Cities now house half the world s population and produce 70 percent of its GDP. Managing them well helps development. Strengthening municipal management of planning, finance, and service provision has been at the core of World Bank support through municipal development projects (MDPs). This book reviews how, worldwide, nearly 3,000 municipalities have benefitted from 190 World Bank-supported MDPs over the past decade, three quarters of which achieved satisfactory outcomes. The finance dimension of MDPs computerized accounting, revenue generation, and municipal credit produced some of the best results, but weaker outcomes came from attempts to stimulate private finance of municipal services. City planning, used by municipalities worldwide, was not a strong priority for MDPs. But building municipal information systems, for example in Chile, were successful. Monitoring and evaluation rarely worked well, except when municipalities themselves were convinced of its usefulness, such as in Russia, Tunisia, and Colombia. Results in managing service provision were mixed. The poverty focus of MDPs was strikingly weak across the portfolio. Cost-benefit analysis rarely prioritized municipal investments. But MDPs helped municipalities strengthen their procurement function. MDPs helped municipalities manage services more effectively. Better results still can come from a stronger poverty focus, more attention to planning and prioritizating investments, and more effective operation and maintenance of such investments.
