67th Street and I-35 Traffic Study

image description

The City of Merriam tasked BHC with conducting the 67th Street and I-35 Traffic Study to evaluate existing traffic movements, safety issues and traffic signal operations. After collecting video-based traffic data, BHC’s traffic engineers examined the performance of the different phases of the traffic signals to identify specific issues and potential adjustments in the timing plan and signal equipment. As part of the on-site signal assessment, BHC was able to adjust the signal timing plan and reduce delays and overall phase length for vehicles by 10-15% without any equipment upgrades. After completing an analysis of the intersection’s overall performance, written recommendations and cost estimates were provided to City staff outlining different options to improve operations and safety at the interchange of 67th Street and I-35.
