Safety and Traffic Operations at Cloverleaf Interchanges

The primary objectives of this research are to: (1) Assess the safety and operational performances of cloverleaf interchanges in Louisiana as compared to the traditional diamond interchanges. (2) Use safety and traffic analysis to predict future performance of cloverleaf and diamond interchanges in Louisiana. (3) Suggest countermeasures/alternative interchange solution that should be implemented if a cloverleaf / diamond interchange is not an appropriate alternative based on their predicted future performance.
