This week in Pittsburgh, the Intelligent Transportation Society America holds its 25th Annual Meeting. And, while that might not mean much to most readers, I can tell you that the people gathering for this week’s conference are making a difference in all of our lives by making our cars safer and our road travel more efficient. I can also tell you that Pittsburgh is a great place for this year’s event because it is home to Carnegie Mellon University where, on a recent visit, I saw firsthand the promising automotive and roadway technologies that CMU students and faculty are developing.
