The Partial Cloverleaf configuration is able to handle the predicted 2040 traffic volumes because of how it diverts the left-turn movements. In the No-Build alternative the highest volumes were the through movements across the bridge. Major delays were created when these movements were being stopped by high left-turn volumes. The findings from the evaluation of the field and simulation data indicate that a rational approach to interchange type selection and operational evaluation is feasible using the critical movement analysis approach. Background: Several previous studies, based upon wrong-way driving (WWD) crash history, have demonstrated that partial cloverleaf (parclo) interchanges are more susceptible to WWD movements than others. The capacity deficiency at the crossroad ramp terminal can lead both to excessive delay for off-ramp motorists and to rear-end accidents at the end of the queue. 3 7 + 0 0 s e e t r o l l 1 combined public hearing map c o m b i n e d p u b l i c h e a r i n g m a p roll 2 of 4 r o l l 2 o f 4 b u n c o m b e c o u n t y buncombe county f. a. project stpims-040-1(188)42 5.
