Warming up to WMA: Applications by Northern States
Overview
Interest in Warm Mix Asphalt (WMA) technologies is increasing among state and local transportation agencies in northern states. To shed light on the WMA state of practice in northern states, MnDOT in cooperation with the Transportation Engineering and Road Research Alliance (TERRA) contracted with the Transportation Enterprise Program at Michigan Technological University to deliver a webinar on the state of practice of WMA in the region. Webinar Information Sheet (PDF)
The Transportation Enterprise is an undergraduate research program at Michigan Tech. Through the program, teams of students explore and develop recommendations or solutions for current industry problems and challenges.
Advanced LED Warning Signs for Rural Intersections Powered by Renewable Energy
This report presents the results of a two-year study on the development and evaluation of an Advanced Light-Emitting Diode (LED) Warning System powered by solar panels and rechargeable batteries to be used on rural through/stop intersections with static warning systems that have proven ineffective.

“There are some things one product can do better than others. Agencies should think about the type of data that’s most important to them, and then look at each product’s accuracy and cost to make the best choice for their needs.”

Effects of 24-Hour Headlight Use on Traffic Safety
Introduction
Daytime running lights—generally low-wattage headlights that turn on automatically when a vehicle’s ignition is started—are a safety feature intended to reduce multiple-vehicle crashes during daylight hours by making vehicles more conspicuous to other drivers. In some countries, such as Canada, they are required to be standard equipment on all vehicles manufactured; in the United States they are
permitted but not required, and were standard equipment on about 27 percent of new vehicles manufactured in 2005 (NHTSA, 2008).
