Surveying natural populations / by Hayek, Lee-Ann C.(CARDINAL)331386; Buzas, Martin A.(CARDINAL)287485;

Includes bibliographical references (pages 527-531) and index.Introduction -- Density : mean and variance -- Normal and sampling distributions for fieldwork -- Confidence limits and intervals for density -- How many field samples? -- Spatial distribution : the power curve -- Field sampling schemes -- Species proportions : relative abundances -- Species distributions -- Regression : occurrences and density -- Species occurrences -- Species diversity : the number of species -- Diversity indices -- SHE analysis.Surveying Natural Populations is a user-friendly primer to the essential survey methodologies of quantitative field ecology, or paleoecology, integrating the intuitive approach of the field researcher with the rational analytical tools of the statistician. The chapters guide the uninitiated step by step through such topics as estimating population densities, determining adequate sample sizes, estimating the relative abundance of species, and measuring and modeling diversity. Employing a single data set for clarity, the book demonstrates the application of a wide spectrum of statistical techniques to this model. A wealth of other examples from the natural world illustrates the use of each method with different kinds of organisms. Designed as a comprehensive introduction and handy methodological reference for students and professionals alike, this book is filled with lucid explanations, real-world examples, practice problem sets, more than one hundred illustrations and tables, and many applications to research issues of current concern. For zoologists, botanists, archaeobotanists, archaeologists, and paleontologists, Surveying Natural Populations is a clear and creative guidebook to the range of sophisticated statistical techniques at their disposal.

A study of the feasibility of using photo-radar for traffic speed enforcement in Virginia / by Lynn, Cheryl.(CARDINAL)311173; Virginia Transportation Research Council.(CARDINAL)195142;

Includes bibliographical references (pages 18-20).Final report.Because of increasing difficulties in enforcing posted speed limits on the Capital Beltway around Washington, D.C., local officials proposed that experiments be conducted with photo-radar to determine if that method of automated speed enforcement (widely used in Europe for about 30 years and very recently employed in the western United States) could help reduce average speed and speed variance. A project task force led by the Virginia Department of State Police, with assistance from the Maryland Department of State Police and the Virginia and Maryland Departments of Transportation, and with technical assistance from the Virginia Transportation Research Council, conducted site visits to cities in Europe and the United States where photo-radar is being used. The task force also invited six manufacturers of photo-radar equipment to staff and demonstrate their equipment. Five of the manufacturers conducted a 2-week series of tests on sections of interstate highways with varying volumes of traffic and different traffic characteristics. The tests, which were conducted from June through September 1990, were designed to provide the evaluators with data on the accuracy, reliability, and efficiency of each unit (in terms of the number of speeding cases that could potentially be generated by the use of photo-radar on the Beltway) and help the study team determine if photo-radar could be successfully deployed on the Capital Beltway as an enforcement tool. In addition, the project included an analysis of legal and constitutional issues associated with photo-radar use as well as an evaluation of public sentiment concerning photo-radar use on the Capital Beltway. The evaluators concluded that photo-radar use was feasible on high-speed, high-volume roads such as the Capital Beltway and, therefore, recommended efforts to pass state enabling statutes and test further the efficacy of photo-radar in actual traffic enforcement conditions.Sponsored by Virginia Department of Transportation, University of Virginia, [and] Virginia Dept. of State Police, under a grant awarded by the National Highway Traffic Safety Administration, contract no.

Automated speed enforcement pilot project for the Capital Beltway : feasibility of photo-radar / by Lynn, Cheryl.(CARDINAL)311173; Virginia Transportation Research Council.(CARDINAL)195142;

Includes bibliographical references (pages 75-82).Final report.Because of increasing difficulties in enforcing posted speed limits on the Capital Beltway around Washington, D.C., local officials proposed that experiments be conducted with photo-radar to determine if that method of automated speed enforcement (widely used in Europe for about 30 years and very recently employed in the western United States) could help reduce average speed and speed variance.

Five of the manufacturers conducted a 2-week series of tests on sections of interstate highways with varying volumes of traffic and different traffic characteristics.

In addition, the project included an analysis of legal and constitutional issues associated with photo-radar use as well as an evaluation of public sentiment concerning the use of photo-radar on the Capital Beltway. The evaluators concluded that photo-radar use was feasible on high-speed, high-volume roads such as the Capital Beltway and, therefore, recommended efforts to pass state enabling statutes and test further the efficacy of photo-radar in actual traffic enforcement conditions. Although the results of the study indicate that it is feasible to use photo-radar on high-speed multilane roadways, further study is required to determine its effect on travel speed and safety. There are also important operational issues that must be considered when using this device. Some items of consideration are identification and selection of operational sites and times to deal with identified traffic safety and enforcement problems; provision of equipment-specific training programs for police officers to ensure the equipment is properly operated; provision for the availability of properly trained technical support personnel to ensure the continuing accuracy of the equipment; setting of speed thresholds that are realistically determined and target the excessive speeder; number of lanes on the roadway; visual obstructions on the roadway; and customizing of photo-radar applications to fit the highway safety problem area.Sponsored by Virginia Department of Transportation, University of Virginia, [and] Virginia Dept. of State Police, under a grant awarded by the National Highway Traffic Safety Administration, contract no.
