The implementation of the American Association of State Highwayand Transportation Officials\ue2\u20ac\u2122 Highway Safety Manual (HSM) methodologies isexpected to provide a cost-effective approach to transportation safety planning andengineering. However, the safety performance functions for HSM\ue2\u20ac\u2122s predictivemethod were developed using data from states other than Maryland (California andWashington). Therefore, Local calibration factors (LCFs) need to be developed toapply HSM\ue2\u20ac\u2122s predictive method to Maryland
