摘要: Objective: The objective of this research is to develop safety performance functions (SPFs) on 2-lane rural roads predict the number injury crashes per year 108 vehicles/km road segment using a study influence human factors (gender, age, drivers) and scenario (combination infrastructure environmental conditions found at site time crash) effects crash by varying dynamic. Countermeasures are suggested reduce rate include different awareness campaigns structural measures segments road. Methods: An 8-year period was analyzed for which 5 years information were used calibrate specify SPFs remaining 3 years check reliability equations. Before moving calibration phase, technique filter anomalous rates adopted method widely in geotechnical engineering that based estimates ranges values th...
