MoDOT’s Lessons Learned HORIZONTAL GEOMETRY • Major controlling element of a DDI is the horizontal geometrics which can act as traffic calming. • Regular passenger vehicles: 20-30 mph, to date 25 mph is maximum used • WB 67s: • Through movement: 20 mph • Ramp movement: 15 mph DIVERGING DIAMOND INTERCHANGES ASHE 2010 National Conference June 9-13, 2010
