Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to assist in determining the potential impacts of implementing a proposed 65 mph speed limit on non-freeways in Michigan. Consideration was given to a broad range of performance measures, including operating speeds, traffic crashes and crash severity, infrastructure costs, fuel consumption, and travel times. Specifically, a prioritization strategy was developed to identify candidate MDOT non-freeway road segments possessing lower safety risks and potential infrastructure costs associated with raising the speed limit from 55 to 65 mph. Ultimately, approximately 747 miles of undivided and 26 miles of divided 55 mph non-freeways were identified as lower risk candidates, representing approximately one-eighth of the MDOT systemwide mileage posted at 55 mph. An economic analysis of the anticipated costs and benefits associated with the proposed speed limit increase was performed for these lower risk candidate segments, in addition to a systemwide estimate. As the travel time savings were expected to outweigh the fuel consumption costs, it was necessary to determine if these net operational benefits outweighed the expected infrastructure upgrade costs and increased crash costs. For roadways possessing horizontal and/or vertical alignments that are not compliant with a 65 mph speed limit, an unfavorable benefit/cost ratio would likely result due to the excessive infrastructure costs incurred during 3R (resurfacing, restoration, rehabilitation) or 4R (reconstruction) projects. Crashes were expected to increase for all implementation scenarios, with a particular increase in the risk of fatal and incapacitating injuries. Due to the substantially large infrastructure costs, application of the 65 mph speed limit is specifically not recommended for non-freeway segments requiring horizontal or vertical realignment to achieve design speed compliance. Even for segments where compliance with the increased design speed is maintained, careful consideration must be given to the potential safety impacts particularly to fatal and injury crashes - that may result after increasing the speed limit.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a field implementation of credible, well-enforced, and highly publicized speed limits on two limited access highways in Virginia. The two locations studied were the US 29 bypass around Altavista, VA and the US 58/US 220 bypass around Martinsville, VA. At both of these locations, an engineering study recommended that the posted speed limit be increased from 55 mph to 65 mph. Virginia State Police provided an additional 40 hours per month of overtime enforcement on the study sections for 1 year at the Martinsville site and 15 months at the Altavista site. A public information and education (PI & E) campaign that consisted of media reports, informational handouts, and educational roadside signs was also implemented to try to increase compliance with the new posted speed limits. Before and after data on public perception, crash experience, and speed were analyzed to assess the impact of the program. The public perception survey results showed that the new 65 mph speed limits were well supported by the public, with over 80 percent agreeing with the new speed limits. The speed data analysis showed that the average speed increased by a statistically significant margin of 3 to 4 mph immediately after the new speed limit was implemented. Speeds remained constant following the implementation of the new speed limit, even after the increased enforcement and the education campaign ended. A speed analysis by vehicle type showed some minor variations in how vehicles responded to the changes in speed limit, enforcement, and PI & E. These differences were usually not very large, however. No negative safety impacts were observed during the evaluation. The overall number of crashes did not change by a statistically significant margin relative to historic trends, although the number of severe crashes at the Martinsville site did decline by a statistically significant amount and the crash rate at Altavista showed more than a 20 percent decline. Speed variance did not significantly change between the period with the 55 mph limit and the period with the 65 mph limit. This suggests that crash likelihood was not increased due to the increased posted speed limit. The coefficient of variation of the speeds decreased slightly following the increase in speed limit, potentially indicating that interactions between vehicles may have declined slightly. The demonstration proved to be a success, with the change in speed limit being well supported by the public. Strict compliance with the posted speed limits improved from 5 to 10 percent before the project began to between 45 and 50 percent. The percentage of drivers traveling 10 mph or more over the limit declined from over 20 percent to only 2 to 3 percent. Survey respondents reported that the roadside signs were noticed the most often of any PI & E effort used, likely due to the fact that both sites were located on through routes in rural areas.

Available in PDF, EPUB and Kindle. Book excerpt: In an increasingly globalised world, despite reductions in costs and time, transportation has become even more important as a facilitator of economic and human interaction; this is reflected in technical advances in transportation systems, increasing interest in how transportation interacts with society and the need to provide novel approaches to understanding its impacts. This has become particularly acute with the impact that Covid-19 has had on transportation across the world, at local, national and international levels. Encyclopedia of Transportation, Seven Volume Set - containing almost 600 articles - brings a cross-cutting and integrated approach to all aspects of transportation from a variety of interdisciplinary fields including engineering, operations research, economics, geography and sociology in order to understand the changes taking place. Emphasising the interaction between these different aspects of research, it offers new solutions to modern-day problems related to transportation. Each of its nine sections is based around familiar themes, but brings together the views of experts from different disciplinary perspectives. Each section is edited by a subject expert who has commissioned articles from a range of authors representing different disciplines, different parts of the world and different social perspectives. The nine sections are structured around the following themes: Transport Modes; Freight Transport and Logistics; Transport Safety and Security; Transport Economics; Traffic Management; Transport Modelling and Data Management; Transport Policy and Planning; Transport Psychology; Sustainability and Health Issues in Transportation. Some articles provide a technical introduction to a topic whilst others provide a bridge between topics or a more future-oriented view of new research areas or challenges. The end result is a reference work that offers researchers and practitioners new approaches, new ways of thinking and novel solutions to problems. All-encompassing and expertly authored, this outstanding reference work will be essential reading for all students and researchers interested in transportation and its global impact in what is a very uncertain world. Provides a forward looking and integrated approach to transportation Updated with future technological impacts, such as self-driving vehicles, cyber-physical systems and big data analytics Includes comprehensive coverage Presents a worldwide approach, including sets of comparative studies and applications
