Positive Guidance is a high payoff, short-range way to enhance safety of substandard facilities. This report presents three types of information to guide the user in applying Positive Guidance. Part I of this report discusses the principles, concepts and terminology underlying Positive Guidance. Part II presents the procedures for performing the eighteen activites required to accomplish Positive Guidance objectives. Part III presents three case studies to show procedure application and product variation brought on by site differences. The three case studies are urban, signalized intersection; interstate freeway segment; and, a rural two lane road.

This report presents results of research conducted under Transit Cooperative Research Program (TCRP) Project B-21, "Effective Approaches to Meeting Rural Intercity Bus Transportation Needs." The project identified strategies for initiating, preserving, and enhancing effective rural intercity bus transportation. To identify recent projects and to identify barriers or issues affecting implementation, the research effort included surveys of state rural transit program managers, state rail program managers, and intercity bus carriers. The report includes three parts. Part I contains a review of recent developments affecting the intercity bus industry, an overview of potential funding sources, and a review of barriers to implementation of rural intercity projects. Part II provides strategies for rural intercity service improvements, including methods of identifying intercity carriers and services, planning, program development, operating assistance, capital assistance, marketing assistance, and combining approaches. Each strategy is described, and implementation examples are presented. Part III presents 50 project descriptions based on additional survey interviews with project contacts.

Timber's strength, light weight, and energy-absorbing properties furnish features desirable for bridge construction. Timber is capable of supporting short-term overloads without adverse effects. Contrary to popular belief, large wood members provide good fire resistance qualities that meet or exceed those of other materials in severe fire exposures. From an economic standpoint, wood is competitive with other materials on a first-cost basis and shows advantages when life cycle costs are compared. Timber bridges can be constructed in virtually any weather conditions, without detriment to the material. Wood is not damaged by continuous freezing and thawing and resists harmful effects of de-icing agents, which cause deterioration in other bridge materials. Timber bridges do not require special equipment for installation and can normally be constructed without highly skilled labor. They also present a natural and aesthetically pleasing appearance, particularly in natural surroundings. The misconception that wood provides a short service life has plagued timber as a construction material. Although wood is susceptible to decay or insect attack under specific conditions, it is inherently a very durable material when protected from moisture. Many covered bridges built during the 19th century have lasted over 100 years because they were protected from direct exposure to the elements. In modem applications, it is seldom practical or economical to cover bridges; however, the use of wood preservatives has extended the life of wood used in exposed bridge applications. Using modem application techniques and preservative chemicals, wood can now be effectively protected from deterioration for periods of 50 years or longer. In addition, wood treated with preservatives requires little maintenance and no painting. Another misconception about wood as a bridge material is that its use is limited to minor structures of no appreciable size. This belief is probably based on the fact that trees for commercial timber are limited in size and are normally harvested before they reach maximum size. Although tree diameter limits the size of sawn lumber, the advent of glued-laminated timber (glulam) some 40 years ago provided designers with several compensating alternatives. Glulam, which is the most widely used modem timber bridge material, is manufactured by bonding sawn lumber laminations together with waterproof structural adhesives. Thus, glulam members are virtually unlimited in depth, width, and length and can be manufactured in a wide range of shapes. Glulam provides higher design strengths than sawn lumber and provides better utilization of the available timber resource by permitting the manufacture of large wood structural elements from smaller lumber sizes. Technological advances in laminating over the past four decades have further increased the suitability and performance of wood for modern highway bridge applications.

This is a print on demand edition of a hard to find publication. Explores whether sufficient data exists to examine the temporal and spatial relationships that existed in terrorist group planning, and if so, could patterns of preparatory conduct be identified? About one-half of the terrorists resided, planned, and prepared for terrorism relatively close to their eventual target. The terrorist groups existed for 1,205 days from the first planning meeting to the date of the actual/planned terrorist incident. The planning process for specific acts began 2-3 months prior to the terrorist incident. This study examined selected terrorist groups/incidents in the U.S. from 1980-2002. It provides for the potential to identify patterns of conduct that might lead to intervention prior to the commission of the actual terrorist incidents. Illustrations.
