IMPLEMENTATION OF MODERN STATISTICAL METHODS FOR IMPROVING THE ACCURACY OF HIGHWAY LABORATORY AND FIELD DATA - A MANUAL

Accident rate, traffic count, accident severity index, proportion of wet surface accidents, pavement friction coefficients, highway noise levels, aggregate gradations, etc., are parameters commonly used in the transportation field. The estimated values of these parameters are often the basis of information used in administrative decision making, e.g., the development of effective safety improvement and testing programs. Highway administrators also use parameter estimates to develop effective quality control systems. This report demonstrates that estimation errors significantly affect the accuracy of the developed program guidelines and, consequently, decisions based on these guidelines.
