B&M"s team completed an extensive Design-Build Intelligent Transportation System (ITS) project for PennDOT. The $8 million-dollar project took more than three years to finish.

The project was in Chester County, PA along the Route 30 Bypass. It focused on an 18-mile stretch of the highway, running west from Exton to Parkesburg. PennDOT commissioned the project in preparation for future construction on the bypass. Project Manager Larry H. led our team, whose job was to design an ITS that will track, measure and reroute traffic through the Route 30 business corridor once construction begins.

The project included seven Dynamic Message Signs (DMS), 24 CCTV cameras, 18 Travel Time System (TTS) Bluetooth readers, 81 traffic signal timers and one hub location. All of these devices were linked to the PennDOT Traffic Management Center (TMC) and eight local municipalities through a fiber-optic network. The network used existing PennDOT FO cable as well as 30 miles of new FO cable that our team installed, terminated and tested.

One of the biggest challenges on the project came before work even began. During the design process, the scope increased by approximately 55%.

“Several locations were changed,” Larry reported. “We added five more cameras, 48 intersection timers, one Bluetooth server and all the necessary infrastructure to complete the work.”
