Application exercise
In teams, participants will discuss potential applications of alternative designs at the following three intersections:US 151 - Rural expresswaySR 7 - Arterial in developing suburb
US 167 - Urban arterialSlide3

Context and conditions
Rapidly developing suburban land useCommercial on north sideResidential / mixed-use on south side Currently STOP control at both minor road approachesHeavy through volumes on arterial45 mph posted speed – higher operating speedsResidents and businesses are complaining about delay waiting to turn out from minor roads – they want a signal!Slide11
