MDOT - Reconnecting Mississippi's Coastal Communities Through ITS


Reconnecting Mississippi’s Coastal Communities Through ITS

 As Mississippians began clearing the wreckage and rebuilding their communities after Hurricane Katrina, the Mississippi Department of Transportation (DOT) immediately embarked on a plan to rebuild U.S. Highway 90 along the state’s coastline.

For Mississippi DOT, the emphasis was not just on replacing what had been, but taking the opportunity to build back better than before. For a constrained corridor that could not be widened, this meant engaging local jurisdictions in a collaborative partnership to build smarter with ITS elements maximizing the corridor’s capacity.

The plan would bring state-of-the-art traffic management capabilities along the 43-mile corridor with 54 signalized intersections spanning six cities and two counties. A huge challenge and yet a huge opportunity, Mississippi DOT worked not just to replace what was destroyed, but make use of the latest and most appropriate ITS technologies to meet existing and future transportation needs for U.S. 90 and the region.

MDOT, faced with a seemingly insurmountable challenge between the devastation of the storm and the fact that Highway 90 could not be widened to accommodate the ever growing traffic demands of this corridor, turned to InLine to provide a Design-Build Solution for an Intelligent Transportation System (ITS) that would enable real-time traffic monitoring and incident management as well as a number of other applications including Video Detection Systems (VDS) and Adaptive Signal Control (ASC) along this corridor allowing more vehicles to travel safely down the same road space in an efficient manner.

This system also enables these communities the ability to provide telecommunication services to other agencies or connect camera and ITS elements to additional highways, interstates, or arterial streets throughout the estimated 1500 square miles of coverage area.
