An evaluation of the Parent-Taught Driver Education (PTDE) program in Texas was conducted using three different research techniques: (1) focus groups with driver education instructors, teen drivers, and their parents; (2) a statewide mail survey of young drivers; and (3) an analysis of Texas driver records
Modeling of hot-mix asphalt compaction a thermodynamics-based compressible viscoelastic model ( )
2 editions published in 2010 in English and held by 171 WorldCat member libraries worldwide
Compaction is the process of reducing the volume of hot-mix asphalt (HMA) by the application of external forces. As a result of compaction, the volume of air voids decreases, aggregate interlock increases, and interparticle friction increases. The quality of field compaction of HMA is one of the most important elements influencing asphalt pavement performance. Poor compaction has been associated with asphalt bleeding in hot weather, moisture damage, excessive aging and associated cracking, and premature permanent deformation. This study was conducted to develop a model within the context of a thermomechanical framework for the compaction of asphalt mixtures. The asphalt mixture was modeled as a nonlinear compressible material exhibiting time-dependent properties. A numerical scheme based on finite elements was employed to solve the equations governing compaction mechanisms. The material model was implemented in the Computer Aided Pavement Analysis (CAPA-3D) finite-element (FE) package. Due to the difficulty of conducting tests on the mixture at the compaction temperature, a procedure was developed to determine the model's parameters from the analysis of the Superpave® gyratory compaction curves. A number of mixtures were compacted in the Superpave® gyratory compactor using an angle of 1.25 degrees in order to determine the model's parameters. Consequently, the model was used to predict the compaction curves of mixtures compacted using a 2-degree angle of gyration. The model compared reasonably well with the compaction curves. FE simulations of the compaction of several pavement sections were conducted in this study. The results demonstrated the potential of the material model to represent asphalt mixture field compaction. The developed model is a useful tool for simulating the compaction of asphalt mixtures under laboratory and field conditions. In addition, it can be used to determine the influence of various material properties and mixture designs on the model's parameters and mixture compactability

Minimum retroreflectivity levels for blue and brown traffic signs by Andrew J Holick ( )
3 editions published in 2008 in English and held by 166 WorldCat member libraries worldwide
In 2003, the Federal Highway Administration published research recommendations for minimum maintained retroreflectivity (MR) levels for traffic signs. The recommendations included most sign types but not white-on-blue signs or white-on-brown signs. In addition, the 2003 recommended maintained retroreflectivity levels were based on conditions representing dark rural environments. This report describes the research activities and consequent findings related to the development of recommendations for MR levels for white-on-blue signs and white-on-brown signs. This report also includes an investigation related to MR levels needed for complex visual conditions that include glare from oncoming headlamps and fixed roadway lighting. The research used a summary of the pertinent literature to develop an experimental plan to produce luminance thresholds that could be used with a previously developed analytical model to develop a set of recommendations for MR levels for white-on-blue signs and white-on-brown signs. The results for the white-on-blue signs and the white-on-brown signs were integrated into one table that includes the current set of MR levels. Both legend and symbol signs were consolidated into the same recommendations because of similar requirements for luminance thresholds
A primer on work zone safety and mobility performance measurement by Gerald L Ullman ( Book )
1 edition published in 2011 in English and held by 163 WorldCat member libraries worldwide
This primer has been developed to assist agencies in establishing and monitoring a useful set of work zone safety and mobility performance measures. The primer describes possible work zone performance measures, and provides guidance to help agencies select and implement measures that make sense for their own work zone programs. The primer outlines the methods and technologies that are available to gather data to monitor the various possible measures and procedures for calculating specific performance measures from different types of work zone traffic monitoring data. The primer also discusses the use of measures across multiple projects to assess an agency's overall efforts and outcomes against its policies and goals

Traffic incident management quick clearance laws a national review of best practice by Jodi L Carson ( )
1 edition published in 2008 in English and held by 144 WorldCat member libraries worldwide
Constituting 'Quick Clearance Laws', three types of general legislation Move Over, Driver Removal, and Authority Removal laws - support concurrent Quick Clearance operations intended to enhance motorist and responder safety, as well as reduce congestion and delay. Although a number of States currently have one or more of these laws in place, observed variability in the existence, wording, and coverage of Quick Clearance Laws challenges further implementation. The intent of this investigation was to better support Quick Clearance Law implementation efforts by better preparing States to respond to questions regarding the necessity of Quick Clearance legislation and identifying examples from existing State Move Over, Driver Removal, and Authority Removal legislation that serve to both support and challenge successful incident management operations. Through this investigation, carefully crafted statutory content and language that best support Quick Clearance objectives, and agency/industry partnerships that provide demonstrated, united support for safe, Quick Clearance objectives and related legislation were observed to be key factors supporting implementation of Quick Clearance Laws. This report includes: (1) a description of the role and relevance of Quick Clearance Laws in the broader traffic incident management context; (2) a detailed review of the purpose and intent, model language, observed content trends and anomalies, and implementation challenges and resolutions for Move Over, Driver Removal, and Authority Removal laws including specific examples from State legislation; and (3) concluding remarks and proposed strategies for implementation, including beneficial synergy resulting from combined Quick Clearance Law implementation

Safety effectiveness of the HAWK pedestrian crossing treatment by Kay Fitzpatrick ( )
1 edition published in 2010 in English and held by 139 WorldCat member libraries worldwide
The High intensity Activated crossWalK (HAWK) is a pedestrianactivated beacon located on the roadside and on mast arms over major approaches to an intersection. It was created in Tucson, AZ, and at the time of this study, it was used at more than 60 locations throughout the city. The HAWK head consists of two red lenses over a single yellow lens. It displays a red indication to drivers when activated, which creates a gap for pedestrians to use to cross a major roadway. A before after study of the safety performance of the HAWK was conducted. The evaluations used an empirical Bayes (EB) method to compare the crash prediction for the after period if the treatment had not been applied to the observed crash frequency for the after period with the treatment installed. To develop the datasets used in this evaluation, crashes were counted if they occurred within the study period, typically 3 years before the HAWK installation and 3 years after the HAWK installation or up to the limit of the available crash data for the after period. Two crash datasets were created. The first dataset included intersecting street name (ISN) crashes, which were all crashes with the same intersecting street names that matched the intersections used in the study. The second dataset included intersection related (IR) crashes, which were only those ISN crashes that had yes for the intersection related code. The crash types that were examined included total, severe, and pedestrian crashes. From the evaluation that considered data for 21 HAWK sites (treatment sites) and 102 unsignalized intersections (reference group), the following changes in crashes were found after the HAWK was installed: a 29 percent reduction in total crashes (statistically significant), a 15 percent reduction in severe crashes (not statistically significant), and a 69 percent reduction in pedestrian crashes (statistically significant)
