Development of Analysis Methods Using Recent Data (D)

The objective of this project is to identify/develop analytic methods for the Strategic Highway Research Program 2 (SHRP2) driving behavior and crash risk study and to carry out demonstrations of the methods using data from recent field studies for road departure and intersection safety issues. Key aspects of the analysis include the application of crash surrogate approaches (traffic conflicts, critical incidents, near-collisions, and other surrogate measures), development of exposure-based collision risk measures, and the formulation of analytic methods to quantify the relationship of human factors, driver behavior, vehicle, roadway and environmental factors to collision risk. The project includes: (1) identification of research questions, (2) review of data from recent studies, (3) development of an analysis plan that specifies risk measures to be used (including crash surrogates), response variables, control variables, and analysis methods, and (4) demonstration of the method using existing data from recent studies.
