Unreferenced date August 2010 A traffic conflict , in transportation engineering , is an event involving two or more moving vehicles approaching each other in a traffic flow situation in such a way that a traffic collision would ensue unless at least one of the vehicles performs an emergency maneuver . Traffic conflicts are defined by their time to collision , post encroachment time , and angle of conflict parameters as well as the vehicles position in time and space. Traffic conflicts have typically been used for transportation safety studies, whereby observing and monitoring individual collisions may be impractical, unfeasible, or unsafe. Traffic conflicts are used as traffic collision surrogates, under the assumption that the same factors affecting collision rates also affect conflict rates, in proportion to the conflict severity, termed conflict hierarchy . The principles of traffic conflicts apply to all modes of transportation involving vehicles operating in a non guided medium, including motorized vehicles , Conflict air traffic control Conflicts airplanes , boats, and bicycles. History Empty section date September 2010 By modes of transportation Motorized vehicles Most traffic conflicts involving motorized vehicles are observed on highways, usually involving lane changing or sudden changes in vehicle speeds rear end collision s , or in intersections, involving a large array of conflict types. Methodology Traffic conflicts are complicated events to define visually. Observers are trained to spot traffic conflicts using the same set of videos. Recently, research has shifted towards automated conflict detection with the advent of traffic video analytics and faster processing power. The Federal Highway Administration sponsored Safety Surrogate Assessment Model is a tool being developed for the analysis of conflicts using simulated results from traffic microsimulation . Criticism Some research suggests that the correlation between conflicts and collisions is weak, ... more details
Health Forecasting UCLA is based at the UCLA School of Public Health and works closely with the Los Angeles County Department of Public Health and California Department of Health Services . The goal of the Health Forecasting ref http www.health forecasting.org Health Forecasting ref project is to improve population health and reduce or eliminate health disparities through the development and communication of sound, credible forecasts of how the future health of populations and sub populations can be improved by implementation of effective evidence based public health policies and programmatic interventions. It is projected that the demographics of the United States will make dramatic racial and ethnic distribution shifts in the coming decades. These changes will result in different health outcomes for the emerging population groups, who will be disproportionately affected due to existing health outcome disparities. At the core of this work is the Health Forecasting Tool ref http www.health forecasting.org Model Health Forecasting Tool ref , a simulation model and web based interface that allows anyone from high level government to local communities to access information that gauges the future health impacts of changes in programs and policies on populations. This information is customizable to suit the needs of a unique population by allowing the user to specify geographic boundaries and distributions of race, ethnicity, age, and gender. Results are displayed in easy to read graphic charts and reports. The statistical model was based on research by Statistics Canada as a comprehensive framework that promotes understanding and thinking about human health at the population level. This framework provides a practical implementation foundation that integrates many concepts and ideas utilizing continuous time microsimulation . Web based data sharing has been shown to increase access to data and analytic methods that were previously the exclusive domain of researchers. Hea ... more details

The Tax Policy Center TPC is a non partisan joint venture of the Urban Institute and the Brookings Institution . Based in Washington D.C. , TPC aims to provide independent analyses of current and longer term tax issues and to communicate its analyses to the public and to policymakers in a timely and accessible manner. The Center combines top national experts in tax, expenditure, budget policy, and microsimulation modeling to concentrate on four overarching areas of tax policy that are critical to future debate fair, simple and efficient taxation, social policy in the tax code, long term implications of tax and budget choices, and state tax issues. History In 2002, tax experts who had served in the Ronald Reagan , George H.W. Bush , and Bill Clinton administrations established the Tax Policy Center to provide unbiased analysis of tax issues. The following year TPC developed a comprehensive tax simulation model to analyze the federal income tax and proposals to change it. That model has evolved to incorporate new and additional data, changes in federal tax law, and other aspects of the tax system and the economy. Staff and Expertise Donald B. Marron Jr. Donald Marron , former member of the President s Council of Economic Advisers and former acting director of the Congressional Budget Office, became the Tax Policy Center Director in May 2010. Co Directors are William Gale , Arjay and Frances Miller Chair in Federal Economic Policy at the Brookings Institution and Eric Toder, Institute Fellow at the Urban Institute . The Center s http taxvox.taxpolicycenter.org TaxVox blog is spearheaded by nationally recognized tax correspondent Howard Gleckman. ref http www.taxpolicycenter.org aboutus staff.cfm Tax Policy Center Staff page ref Current Analyses TPC publications examine the impacts of a variety of tax issues.
