IN ADDITION A BENEFIT/COST ANALYSIS IS PERFORMED WHICH INDICATES THAT THE ENTIRE SYSTEM IS COST EFFECTIVE AT A RATIO OF 1.5, ALTHOUGH ONE FREEWAY SECTION HAD A RATIO OF 5.6. CALL BOX USAGE IS FOUND TO BE RELATED TO NUMBER OF VEHICLES PASSING THE BOX AND DISTANCE TO ALTERNATE AID (NEAREST TELEPHONE).
