NCHRP Report 649/NCFRP Report 3: Separation of Vehicles - CMV-Only Lanes presents an extensive compendium of information about CMV-only lanes and examines major issues and concepts that should be understood in developing new applications of CMV-only lane concepts as a potential method for both easing congestion and reducing the number of traffic accidents on highways. Appendices to this report, including an annotated literature review, performance evaluation criteria, benefits monetization factors and unit costs, and net present value calculations for benefit-cost analysis, are available on the TRB website. This report and the supplemental information can be used by public agencies that may be considering CMV-only lane concepts in corridor studies or other planning applications. The report provides data such agencies can use to support their own evaluations of CMV-only lane projects.

Named by Newsweek magazine to its list of "Fifty Books for Our Time." For sixteen years William Whyte walked the streets of New York and other major cities. With a group of young observers, camera and notebook in hand, he conducted pioneering studies of street life, pedestrian behavior, and city dynamics. City: Rediscovering the Center is the result of that research, a humane, often amusing view of what is staggeringly obvious about the urban environment but seemingly invisible to those responsible for planning it. Whyte uses time-lapse photography to chart the anatomy of metropolitan congestion. Why is traffic so badly distributed on city streets? Why do New Yorkers walk so fast—and jaywalk so incorrigibly? Why aren't there more collisions on the busiest walkways? Why do people who stop to talk gravitate to the center of the pedestrian traffic stream? Why do places designed primarily for security actually worsen it? Why are public restrooms disappearing? "The city is full of vexations," Whyte avers: "Steps too steep; doors too tough to open; ledges you cannot sit on. . . . It is difficult to design an urban space so maladroitly that people will not use it, but there are many such spaces." Yet Whyte finds encouragement in the widespread rediscovery of the city center. The future is not in the suburbs, he believes, but in that center. Like a Greek agora, the city must reassert its most ancient function as a place where people come together face-to-face.

This research addresses the growing number of trucks in Texas by developing tools for evaluating needs for special truck facilities, developing a truck route system, and developing recommendations for demonstration of a pilot system. Tasks required to accomplish these objectives began with a comprehensive literature review, to include the major corridor studies and an evaluation of special truck facilities implemented outside of Texas. The research then established criteria for each of the three levels of truck treatments, developed a plan to classify truck facilities, and developed an evaluation framework for these facilities. Based on these tasks, the research then investigated techniques for evaluating levels of service on truck facilities. The techniques were then applied to selected candidate corridors to demonstrate their utility. Finally, the research developed an action plan for implementation of the exclusive truck facilities.

The International Symposium on Dynamics of Vehicles on Roads and Tracks is the leading international gathering of scientists and engineers from academia and industry in the field of ground vehicle dynamics to present and exchange their latest innovations and breakthroughs. Established in Vienna in 1977, the International Association of Vehicle System Dynamics (IAVSD) has since held its biennial symposia throughout Europe and in the USA, Canada, Japan, South Africa and China. The main objectives of IAVSD are to promote the development of the science of vehicle dynamics and to encourage engineering applications of this field of science, to inform scientists and engineers on the current state-of-the-art in the field of vehicle dynamics and to broaden contacts among persons and organisations of the various countries engaged in scientific research and development in the field of vehicle dynamics and related areas. IAVSD 2017, the 25th Symposium of the International Association of Vehicle System Dynamics was hosted by the Centre for Railway Engineering at Central Queensland University, Rockhampton, Australia in August 2017. The symposium focused on the following topics related to road and rail vehicles and trains: dynamics and stability; vibration and comfort; suspension; steering; traction and braking; active safety systems; advanced driver assistance systems; autonomous road and rail vehicles; adhesion and friction; wheel-rail contact; tyre-road interaction; aerodynamics and crosswind; pantograph-catenary dynamics; modelling and simulation; driver-vehicle interaction; field and laboratory testing; vehicle control and mechatronics; performance and optimization; instrumentation and condition monitoring; and environmental considerations. Providing a comprehensive review of the latest innovative developments and practical applications in road and rail vehicle dynamics, the 213 papers now published in these proceedings will contribute greatly to a better understanding of related problems and will serve as a reference for researchers and engineers active in this specialised field. Volume 1 contains 78 papers under the subject heading Road.
