AASHTO Guidelines for Traffic Data Programs by American Association of State Highway and Transportation Officials. Joint Task Force on Traffic Monitoring Standards Pdf
The objective of these AASHTO Guidelines is to improve the quality of the traffic information that supports decisions at all levels of the transportation profession. The Guidelines provide a reference for professional traffic monitoring and establish a process for adoption of national traffic nomitoring standards. They specifically address concerns of state transportation agencies.
Highway Safety: Improved Monitoring and Oversight of Traffic Safety Data Program are Needed: Report to Congressional Committees by Anonim Pdf
This report examines the quality of state crash information; the activities states undertook using 411 grant funds to improve their traffic safety data systems, and the progress they made using the grant funds; and NHTSA's oversight of the grant program
Using the Engineering Literature by Bonnie A. Osif Pdf
With the encroachment of the Internet into nearly all aspects of work and life, it seems as though information is everywhere. However, there is information and then there is correct, appropriate, and timely information. While we might love being able to turn to Wikipedia for encyclopedia-like information or search Google for the thousands of links

Data, Survey Methods, Traffic Monitoring, and Asset Management by National Research Council (U.S.). Transportation Research Board Pdf
TRR no. 1993 includes 22 papers that explore revenue risk mitigation in transportation project financing, traffic sign asset management, estimating highway investment requirements, estimating design hourly volumes, traffic prediction, digital dashboards, random count site selection, wireless location technology-based traffic monitoring, traffic flow impact on travel time variability, and transferability of National Household Travel Survey data. This issue of the TRR also examines the impact of nonresponse and weighting in a travel survey, data integration impact on travel behavior indicators, iterative proportional fitting algorithm for combining traffic count data with missing dimensions, an electronic freight theft management system using Internet-based mapping, and regional routing model for strategic waterway analysis. It also reviews the Highway Capacity Manual adjustment factor for annual weekday to annual average daily traffic, automated consensus-based data verification, enhancing truck data accuracy using dual-loop event data, video-based vehicle detection and classification system, gross vehicle weight distributions from weigh-in-motion data, detection and tracking of vehicle base fronts for traffic counts and speeds, and customizing quality assessment techniques for traffic data archives.
Bridge Traffic Loading by Eugene OBrien,Andrzej Nowak,Colin Caprani Pdf
There is considerable uncertainty about what level of traffic loading bridges should be designed for. Codes specify notional load models, generally to represent extreme levels of normal traffic, but these are often crude and have inconsistent levels of safety for different load effects. Over the past few decades, increasing quantities of reliable truck weight data has become available and it is now possible to calculate appropriate levels of bridge traffic loading, both for specific bridges and for a road network. Bridge Traffic Loading brings together experts from all over the world to deliver not just the state-of-the-art of vertical loading, but also to provide recommendations of best-practice for all the major challenges in the field – short-span, single and multi-lane bridge loading, dynamic allowance and long-span bridges. It reviews issues that continue to be debated, such as which statistical distribution is most appropriate, whether free-flowing or congested traffic governs and dealing with future traffic growth. Specialist consultants and bridge owners should find this invaluable, as will regulators.
Highway Research by Institution of Civil Engineers (Great Britain) Pdf
The level of research activity in the highway sector as a whole has declined precipitously in recent decades, whilst the challenges facing US state highway agencies have escalated. As a result, a Strategic Highway Research Program - SHRP) was initiated to establish collaboration with research bodies tackling similar highway problems in countries worldwide. This collection of reports from around the world presents SHRP`s progress towards providing research-based new products from which the international highway engineering community may benefit. SHRP concentrates on six high-priority research areas: asphaltic materials; pavement performance; cement and concrete; maintenance cost effectiveness; concrete bridge component protection systems and the chemical control of snow and ice.
Traffic Records Program Assessment Advisory by United States. National Highway Traffic Safety Administration Pdf
This updated edition of Traffic Records Program Assessment Advisory gives States information on the contents, capabilities, and data quality of an effective traffic records system by describing an ideal system that supports high-quality decisions and leads to cost-effective improvements in highway and traffic safety. In addition, the updated Advisory outlines a comprehensive approach for assessing the systems and processes that govern the collection, management, and analysis of traffic records data. The Advisory now provides a uniform set of questions derived from the ideal system as described above. The questions are used by a group of qualified independent assessors to determine how close a State's capabilities come to the described ideal. There are three gradations: (a) meets the description of the ideal traffic records system, (b) partially meets the ideal description, and (c) does not meet the ideal description. The Advisory also provides State respondents with standards of evidence that identify the specific information necessary to answer each assessment question. This assessment instrument highlights a State traffic records system's strengths as well as opportunities for improvement.
