| This heavily traveled, 3.9-mile-long corridor needed rehabilitation and widening to accommodate growing traffic demands. The Michigan Department of Transportation (MDOT) foresaw potential challenges regarding traffic delays during construction, and solicited assistance in developing the final traffic signal timing, phasing and coordination plans to be programmed into the new controllers.
Benesch analyzed various staging scenarios for both delays and queues utilizing Synchro/SimTraffic as part of the Traffic Management Plan (TMP). Recommendations involving traffic staging plans, reasonable construction work zone sizes and minimizing traffic impacts were given to MDOT to utilize in developing final maintenance of traffic and engineering plans. Benesch also developed the detailed individual traffic signal controller timing settings for both under construction and final conditions. Twelve different timing sheets (permits) were developed. |

Project highlights
- High volume 3.9-mile corridor with five signalized intersections including advance cross-over signals (Michigan left-turns)
- Analyzed different traffic configuration scenarios to minimize construction delays and damaging queues using Synchro/SimTraffic
- Completed Traffic Management Plan (TMP) Report Developed “”after improvement”” traffic signal phasing and timing plans including coordination plans for morning, evening and off peak periods
- Required experience and expertise in traffic signal controller operations and programming in order to complete traffic timing sheets for controller programming
