General Motors ASTA North

Milford, Michigan

PEA Group was contracted to provide engineering services to assist in the reconstruction of the Vehicle Dynamics Test Area (VDTA) at the Milford Proving Grounds.

The former City Course pad was pulverized and reconstructed for use by the Active Safety Testing User Group at General Motors Milford Proving Ground. Our team designed the new track, which is now called Active Safety Test Area (ASTA) North, to consists of a 12.5-acre pad and a clothoid run-up road that features three lanes of different radius curves to test lane assist features on new vehicles. The east side of the track features areas with and without fog lines and gravel shoulder for testing. Other areas of the track will receive additional pavement markings in the future to test self-parking and autonomous intersection maneuvering.

This project also included the construction of the new City Course, which was relocated to the Serpentine Course area, and additional pavement was added. A third lane was paved on the east half of the Military Straightaway as well. The total construction cost for this project was $5 million. This was the first phase of a three-year plan for the reconstruction of the entire VDTA (Vehicle Dynamics Testing Area). In 2020, PEA Group will be reconstructing the North Loop and adding a new entrance to VDTA with a ConSpan Bridge.
