WSP is the lead designer for the installation of smart pavement technology along a half-mile section of U.S. 285 north of Fairplay, Colorado. Developed by Kansas City-based Integrated Roadways, the “smart pavement” technology uses precast concrete pavement slabs that are embedded with intelligent transportation system elements—specifically, upgradable sensors capable of identifying where cars are located, the direction they are moving, and how fast they are going.
Smart pavement technology works with all vehicles using the road.
“The sensors in the pavement create a ‘footprint’ of the vehicle on the roadway,” said Tim Harris, WSP client relations manager. “It detects all vehicles, so there is no electronic communication and no special vehicle technology is required.”
The Smart 285 team also includes Kiewit Infrastructure Company as the lead construction firm, and Wichita Concrete Pipe as the concrete panel fabricator.
The design phase of the project started recently, and pending results of a smaller proof-of-concept installation along a Denver roadway, construction on U.S. 285 could begin in spring 2019, with completion of the project targeted for later in the fall of that year. Integrated Roadways will operate and maintain the system for a one-year evaluation period after its completion.
