Prior research has shown that the commonly used "conventional" lane merge design (CLM), specified in the Manual on Uniform Traffic Control Devices (MUTCD), can create long queues during peak hours and large numbers of rear end and side swipe crashes. This project, funded by USDOT through the Gulf Coast Center for Evacuation and Transportation Resiliency at LSU, examined the interactions between driver characteristics and behavior with traffic control configurations. The main focus was to measure the performance of a recently developed merge design known as Joint Lane Merge (JLM) in terms of its effects on driver behavior. The research results provide a better understanding of how individual differences and driver behavior can influence driver safety, and it is hoped that these findings can be used to improve traffic flow in construction zones and evacuation plans.
