Abstract:The objective of network screening should ideally be to not only identify sites for safety
investigation but also to prioritize those sites efficiently. Using roadway, intersection, and
collision data from California, this study compared the performance of methods based on the EB
procedure, the LOSS method, and the Table C method. Two intersection types (rural four leg
stop controlled and rural four leg signalized) and two roadway types (rural two lane roads and
urban freeways) were included in the evaluation.
