MN/WI TRUCKS AND ROUNDABOUTS STUDY
 Pooled Fund
 Focus on how to design for standard semi trucks
 Balance safety with freight mobility
 Did not focus on OSOW (KDOT same time)
 Ideal features that preserve safety goals while not creating
an impediment for trucks
 3 primary outcomes
 Class I, II, & III
CLASS I EXAMPLE
•Off tracking upon entry, moving
through circulating roadway and exit
•Typically single lane roundabout
CLASS II EXAMPLE
•Trucks stay in lane on entry and exit
•Trucks off track in circulating
roadway
•Could be single or multilane
CLASS III EXAMPLE
•Truck designed to stay in lane on
entry circulation and exit
•Almost always a multilane roundabout
THINGS TO CONSIDER
Trucks and roundabouts can work
Trucking Industry cares about safety too
Education is key
Effective outreach takes time and the right
message
THINGS TO CONSIDER (CONT)
What do you want trucks to do when they
approach the intersection?
Design based on Percent vs. actual count
Design or speed a factor when trucks crash in
Roundabouts?
DESIGN OR EDUCATION?
