This book was released on 2007 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continuous growth of freight transportation over recent years has resulted in an increasing proportion of commercial vehicles on our nations' highways which has led to higher truck volumes and more severe truck-related crashes every year. Safety proponents have therefore been advocating for more restrictions to be placed on these commercial vehicles in order to reduce the interaction of these larger vehicles and passenger cars. A popular strategy is the use of different lane restrictions for trucks. However, the effectiveness of these restrictions for trucks differs from case to case due to unique factors of each site, including the type of restriction used, traffic conditions and the geometric characteristics at the site. This has motivated the author to conduct this study to evaluate the impact of these restrictions on traffic operations and safety on freeways with different traffic and geometric characteristics. For the safety evaluation, this research measures the impact of different truck lane restriction strategies (TLRS) using conflict as the measurement of effectiveness (MOE). Conflict has been proven to be highly related to traffic crushes on freeways (FHWA, 1990; Sayed and Zein, 1999; Kaub, 2000). The high frequency of conflicts has also made it possible to collect adequate data for statistical analysis. The MOEs used to evaluate the impact of different lane restrictions on operational performance were lane changes, average speed, speed distribution, and volume distribution. Due to the lack of existing highway locations with different lane restrictions considered in this study, the conflict data were collected using a traffic simulation tool - PARAMICS V3.0 (Quadstone Ltd., 2000), which can simulate the emergent interaction between vehicles but not random crashes on the road network. The effectiveness of different lane restrictions in terms of the above MOEs were evaluated for 14,400 different simulation scenarios by varying lane restriction strategies, traffic conditions (volume, truck percentage) and geometric characteristics (gradient, speed limit, interchange density). The simulation results showed that all the geometric and traffic characteristics had a significant impact on freeway safety and operation. In addition, truck percentage and volume were identified as key factors that had a significant impact on the selection of the optimal truck lane restriction strategy. The ANOVA analyses indicated that the degree of effect of truck lane restriction strategies on safety intensify with the increase in truck percentage and traffic volume. Optimal alternatives of truck lane restriction strategies under different truck percentages and volumes were identified with the objective of reducing traffic conflicts and enhancing LOS (level of service). Guidelines were then developed for the application of truck lane restrictions under alternative traffic and geometric conditions.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is concerned with studies on an effectiveness and impact of lane restriction for large trucks from a left lane on Interstate 40 near Knoxville. The data collection was conducted in July to August 2001 and March to April 2002. The restriction was implemented on August 13, 2001. The lane distribution and individual speed of large trucks in each lane were then gathered to obtain patterns and characteristics of large trucks "before" and "after" the implementation. A database was developed, a data comparison was conducted, and a statistical test was applied. The findings reveal several significant changes of lane distributions and speeds of large trucks and are concluded in the form that can provide the Tennessee department of transportation information in order to make a decision on an existing and future lane use restriction plan.

This book was released on 2024-05-23 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of sustainable road infrastructures has become an issue of concern to the international community. Road infrastructures require a large amount of non-renewable resources during the construction phase while containing abundant renewable energy resources (e.g. vehicle mechanical energy, internal thermal energy, and surface solar energy) during the operational phase. Therefore, reducing the dependence of road infrastructures on non-renewable resources, upgrading the construction and maintenance levels, improving the recycling level of infrastructure materials, and efficiently harvesting and utilizing clean energy from sustainable road infrastructures are of great significance in alleviating energy problems and promoting sustainable social development.

Available in PDF, EPUB and Kindle. Book excerpt: Every day thousands of people are killed and injured on our roads. Millions of people each year will spend long weeks in the hospital after severe crashes and many will never be able to live, work or play as they used to do. Current efforts to address road safety are minimal in comparison to this growing human suffering. This report presents a comprehensive overview of what is known about the magnitude, risk factors and impact of road traffic injuries, and about ways to prevent and lessen the impact of road crashes. Over 100 experts, from all continents and different sectors -- including transport, engineering, health, police, education and civil society -- have worked to produce the report. Charts and tables.
