Planing Strategies Transportation Engineering

Posted by aditya | 3:39 PM | | 1 comments »

On the other hand, in instances where proposals may be challenged or blocked by other agencies or in the political arena or the courts, other strategies may be more appropriate. Among these are those of coordinator or coordinator-catalyst . In this instance the function of the planner or planning team is to provide technical and organizational support, to receive inputs on the needs and goals of affected persons, groups, or agencies, and to incorporate them into planning and decision making. The catalyst role requires that arrangements be worked out under which an exchange of information on needs, goals, and al­ternative solutions of those who are affected are presented, and then, if possi­ble, to aid the decision maker or group in reaching an acceptable solution. Among other suggested strategies not diagramed here are (1) community advo­cacy whereby an individual (ombudsman) represents all community interests or (2) arbitrative, which calls for a. hearing officer who, after evaluating the ap­proaches of the planner on the one hand and the community on the other, makes the final decision.

The stances of planners or technical groups will be quite different under the various strategies. It would be logical where the strategy of information is used to take an authoritative, "I am the expert,” approach. On the other hand, where planners are to be coordinators or catalysts or to work as ombudsmen or com­munity advocates, they can be neither partisan nor advocate a particular solu­tion. Their roles must be those of clarifiers, expeditors, conciliators, and impar­tial negotiators. They must avoid what is called the "Myth of rationality," which is to believe or cause others to believe that they think that, as professionals, they are uniquely qualified to adjudge what is best for society in their fields of com­petence. And they must recognize that their personal value systems and goals are not those of some of the participants

Research and Information Retrieval for Highways and Public Transportation

Posted by aditya | 9:54 AM | , , | 1 comments »

FHWA, UMTA, and many other federal agencies, the individual state highway departments, a number of universities, private or university-related research groups and individuals, and many of the other organizations and associations mentioned here conduct research on highway and transportation problems or provide financing for it. Many other agencies also carry out projects with strong transportation implications. The output from these efforts is large; one estimate places it at 30.000 titles per year. It follows that to find what research has been done or is under way is a difficult task.
Among the ways to find research results are through TRB publications and other services mentioned earlier or in such summaries as the annual Transac­tions of ASCE. Many other agencies, for example FHWA's Highway Institute, publish bibliographies from time to time. The subject indexes in good university and public libraries can be helpful. Unfortunately, many valuable research re­ports, particularly those issued by federal agencies, are not available in libraries unless they are depositories and even their collections may be incomplete.

Even after the titles and abstracts of research reports have been located, gain­ing access to the report itself may be difficult. Copies of some of the most sig­nificant can be purchased from the National Technical Information Service, Springfield, Va. 22151. Often, however, it may be necessary to contact the au­thor or sponsoring agency. Because information retrieval from the vast number of publications is so difficult, those who wish to have their findings known should report them through TRB, ASCE, or other commonly available sources.

Other Transportation and Highway Associations

Numerous trade associations interested in promoting the use of the products of their members are active in the transportation and highway fields. Two in this large group are the Asphalt Institute and the Portland Cement Association. Many of these associations publish technical bulletins and release other data. Some have field engineers located strategically over the country. Much reliable and useful information can be gained from these sources. Certain individual manu­facturers also are active in a similar manner.



Another group of associations includes those having special areas of interest in transportation. One is the American Public Transit Association. The National Safety Council, concerned with accidents, has among its functions the collec­tion, classification, and disti ibution of accident data. The Highway Users Fed­eral for Safety and Mobility, supported by the automotive, oil, and trucking in­dustries, has fostered research and education toward safe and efficient highway transportation. The federation's interests also include highway administration and planning, and it has made significant studies in both fields. The Insurance Institute for Highway Safety has particularly emphasized vehicle design and crash resistance and occupant protection. The Eno Foundation for Transporta­tion, Westport, Connecticut, among other activities, publishes the excellent pe­riodical Traffic Quarterly. The International Road Federation promotes educa­tion, information interchange, and understanding throughout the world.

There are also associations whose concern is highway transportation as it fects their members. Representative of these are the American Automobile As sociation and the American Trucking Association. Most of these also publish magazines or bulletins

Foreign Research Organizations Transportation Department

The United States is not alone in transportation and highway research. An out­standing example of another nation's activities is the Transport and Road Re­search Laboratory, located near Crowthorne, Berkshire, England. Its studies have covered a wide range of subjects dealing not only with the problems of Great Britain, but also with those of the developing nations. It also offers a va­riety of education programs including lectures, seminars, and short courses. Lists of publications and individual research reports are available to officials, researchers, and educators on request. There are similar organizations, too nu­merous to mention, in Canada, continental Europe, and other countries around the world.


Transportation Research Board (TRB)

Posted by aditya | 6:53 PM | , , | 2 comments »


The Transportation Research Board (TRB), organized in 1920 as the Highway Research Board (HRB), is a private, nonprofit organization. It operates within the Commission on Sociotechnical Systems of the National Research Council, which, in turn, is a part of the National Academy of Sciences National Academy of Engineering. TRB is supported financially by all the state transportation and highway departments, FHWA, UMTA, FAA, and FRA, numerous transportation and trade organizations, and many individuals.
The board's primary function is to encourage research in transportation and to provide a forum for the presentation, discussion, and publication of the results. This is done primarily through about 150 committees made up of roughly 1800 administrators, engineers, social scientists, and educators. Its annual meeting is by far the largest single gathering of specialists in transportation.
Another area of board activity is arranging workshops and conferences on special subjects of short-term or long-term importance. These provide a neutral forum where various viewpoints can be presented. The board has also, over the years, carried out a number of sponsored research projects, the most notable of which probably was the $27 million AASHO road test.



Board publications total some 6000 pages per year. Included are the Record series (which in 1962 succeeded the HRB Bulletin series and the annual Proceedings), the Special Report series, a magazine Transportation Research News, which reports six times yearly on current happenings, and a series of Circulars on specific topics. There are also publications on railroad, water, and air transportation topics.
In 1962, the board was assigned direction of the National Cooperative High way Research Program under which the NCHRP staff administers contracts fof research on specific topics selected by AASHTO. Results are published in a ries of NCHRP Reports, NCHRP Syntheses, and NCHRP Research Results. A parallel effort for transit, called the National Cooperative Transit Ro. search and Development Program (NCTRP), was undertaken by TRB Beginning in 1978, with financial support from the Agency for International Development (AID) it produced a series of Compendiums and Syntheses under the title of Transportation Technology Support for Developing Countries.
TRB also operates a computer-based Highway Research Information Services (HRIS) and cooperates in an on-line, computer-based Transportation Research Information Service Network (TRISNET). Through them, abstracts of past research and of research in progress can be obtained quickly. Among other outputs from this system are summaries of reports of completed projects and research in progress.'0 Indexes of TRB publications, compiled at possibly four- year intervals, also come from this data base. These are reported by subject author, and title of each paper.
Without question, the publications of TRB are the most fruitful single source of advanced knowledge concerning highway and public transportation. References in this book are predominantly from its publications.
