The SunTrax Loop Track course design demands an agile response as scenarios such as the urgency to merge lanes or adjust speed in construction zones create unpredictable conditions for dynamic maneuvers.

Test for the Open Road

The Loop Track consists of a three-lane continuous loop, incorporating entrance and exit ramps into multi-lane straightaways that feature several merging and weaving sections. It provides the functionality to test scenarios such as maintenance of traffic flow during active road construction, dynamic lane changing, and collision avoidance. With nearly a mile (1.60 km) of multi-lane roadway, including 3,000 & 2,000 ft (914.40 & 609.60 m) straightaways, the Loop Track provides an optimal, controlled environment for both “gap identification” and “acceptance and speed estimation” tests. It is located on the west side of the facility and can simultaneously support up to twenty vehicles and four users.

Merging Scenarios

Weaving sections, where a merge and a diverge are in close proximity, are considered crucial bottlenecks in the highway network. Testing emerging connected and automated vehicle technology can improve operations and increase capacity through winding road networks.

Collision Avoidance

With its continuous loop design and multi-lane straightaways, the Loop Track provides the ideal conditions to extensively test collision avoidance and preemptive technologies to demonstrate the safety and viability of connected and automated vehicles.
