What IS a:Safety Management System???

A method to A method to reduce fatal collisionsreduce fatal collisions on on roadways. With the reduction of fatal roadways. With the reduction of fatal collisions, all collision types will in turn, be collisions, all collision types will in turn, be reduced on transportation systems.reduced on transportation systems.

A system to obtain funding for roadway and A system to obtain funding for roadway and safety improvements.safety improvements.

Why a:Safety Management System???
