In the News
  • Timothy Gates was featured by several news outlets for the research he will be conducting on whether different freeway speed limits in Michigan for passenger vehicles and large trucks make roads safer. The study is funded by a one year, $175,000 grant from the Michigan Department of Transportation (MDOT). The study will be delivered to MDOT officials, who are expected to consider whether to increase Michigan's speed limit for large trucks and buses.
