SLIC: Speed Limits for Inclement Conditions

Speed limits for inclement conditions, or "SLIC," is a system designed to aid drivers in selecting the appropriate speed of travel when weather conditions are less than ideal. For example, during roadway conditions such as snow, ice, fog, or loose gravel, the safe speed of travel is often less than the posted speed limit. In such cases, SLIC informs the driver of the proper speed via a visual indicator.

SLIC is the product of 5 graduate students in the Human Factors and Applied Cognition program at George Mason University: Jane Barrow, David Cades, David Kidd, Erik Nelson, and Dan Roberts. Send an email to the team here.

The SLIC team was one of three winners of the North American ESV Student Safety Technology Design Competition (21st, 2009), chosen to represent North America at the international competition in Stuttgart, Germany, June 2009.
