Traffic Control Systems Handbook


Book Description

This handbook, which was developed in recognition of the need for the compilation and dissemination of information on advanced traffic control systems, presents the basic principles for the planning, design, and implementation of such systems for urban streets and freeways. The presentation concept and organization of this handbook is developed from the viewpoint of systems engineering. Traffic control studies are described, and traffic control and surveillance concepts are reviewed. Hardware components are outlined, and computer concepts, and communication concepts are stated. Local and central controllers are described, as well as display, television and driver information systems. Available systems technology and candidate system definition, evaluation and implementation are also covered. The management of traffic control systems is discussed.







Target-setting Methods and Data Management to Support Performance-based Resource Allocation by Transportation Agencies


Book Description

Volume III to this report was published separately in an electronic-only format as NCHRP Web-Only Document 154. Volume III includes case studies of organizations investigated in the research used to develop NCHRP Report 666.




Factors that Support the Planning-programming Linkage


Book Description

This report contains a list of 39 factors that influence the linkage between programming and long-range plans. This list was developed from recent literature and extensive interviews with agency staff and other experts in the field. While the discussion of the critical factors is helpful, the report takes this topic one step further by providing suggested paths for improving the linkage between planning and programming.

Sleep Deprivation Countermeasures for Motorist Safety


Book Description

Concludes that although adequate sleep is the only 100 percent effective "countermeasure" for sleepiness, there are other countermeasures to help make driving safer. Several of the key countermeasures include: education of high-risk populations, the general driving public, and other key groups, such as law enforcement personnel, new technologies to detect and warn drowsy drivers, roadway countermeasures such as continuous shoulder rumble strips and other roadway treatments, increased use of rest areas, regulatory and judicial action.
