PROVO, UT—A massive highway construction project in Utah is dramatically changing a stretch of Interstate 15, and the work is impacting side streets and intersections. At one high volume location, the Utah Department of Transportation has set up temporary intersections and equipped them with SmartSensor Matrix, to help manage the flow of traffic in these critical work zones.

The Utah County I-15 Corridor Expansion (I-15 CORE) project is restoring and expanding I-15 in order to meet the area's transportation demands through 2030. Construction teams are adding two lanes in both directions and extending Express/HOV lanes throughout the county. The work also involves the rebuild and reconfiguration of 10 freeway interchanges and the replacement of more than 60 aging bridges.

At Center Street in Provo, crews removed a flyover ramp, creating the need for two temporary intersections on the busy surface street where it connects to I-15's north- and southbound off-ramps. Each intersection is controlled by a single controller and monitored by six Matrix sensors. Matrix generates a 90 degree field of view with a 100 foot range and continuously tracks vehicles while accurately detecting vehicle present at the stop bar. The two intersections are operating efficiently with little delay, despite the complications that exist in work zones.
