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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The findings of the study are two-fold: the results of what forms of multi-modal travel are used by other states and the results of the case study. Many states employ or are planning high occupancy vehicle (HOV) lanes (of all forms/types, but primarily of the concurrent flow variety) for use in urban freeway settings. High occupancy/toll (HOT) lanes were in the planning stages according to about half of the survey respondents while bus rapid transit (BRT) was being considered by two-thirds of the departments responding. Light rail transit (LRT) was only listed in 33% of the responses as being currently in use. HOT Lanes, Exclusive-Use Lanes, By-pass/Separation Lanes, Dual Facilities, and LRT had the highest number of responses for not being used as a multi-modal application within a freeway corridor. The SR 51 case study relied on existing data, modeled situations, and cost estimates to determine the most cost effective choice for multi-modal travel. Existing volume data was provided by Arizona Department of Transportation's Freeway Management System (FMS) and supplemented by a microsimulation study previously conducted for the Arizona Department of Transportation concerning the operations of the existing HOV lanes. Cost data was coalesced from literature review material and transportation data sources exclusive to Arizona. The computations factored in traffic flows under different freeway scenarios depicting different forms of multi-modal travel that would be reasonable for the SR 51 freeway. The results, ranked from most cost-effective to least cost-effective, are as follows (Note: "GP" refers to general purpose lane, and the ranges of cost values are due to different calculation methods for the projected volume by mode): (1) HOT Lane ($0.012 to $0.027 per person-mile) (2) Fourth GP Lane ($0.019 to $0.042 per person-mile) (3) HOV (w/BRT) Lane ($0.026 to $0.057 per person-mile) (existing condition) (4) Exclusive BRT Lane ($0.066 to $0.147 per person-mile) (5) Light Rail Transit ($0.161 to $0.358 per person-mile).

Available in PDF, EPUB and Kindle. Book excerpt: A new road user charge system based on an actual miles traveled basis, or vehicle miles of travel (VMT), is recommended to replace motor fuel taxes, which are in jeopardy due to new vehicle propulsion technologies. This charge would provide a means for crediting states or sub-state jurisdictions for the miles of travel occurring within their boundaries by collecting data from vehicles equipped with intelligent vehicle and GPS technologies. Researchers conclude that a convenient and flexible road user charge system can be designed which will ensure a stable source of revenue for the highway system.
