Green Driving

UGH! Stuck at ANOTHER red light! 

This is Sandra Tsing Loh with the Loh Down on Science.

Don’t you just HATE stop-and-go traffic? It’s not only frustrating, it increases fuel use and emissions! That’s a lose-LOSE! Could SELF-DRIVING vehicles offer a solution?

Enter Vindula Jayawardana and Cathy Wu from the Massachusetts Institute of Technology. They decided to design and test their own navigation method for self-driving… Using computer simulations!

In their method, self-driving vehicles can be taught to MINIMIZE stops at red lights. To make this work, traffic lights and self-driving cars would have sensors. This would let them check in with each other about their surroundings to keep traffic smooth. 

And? If all cars are self-driving, the researchers’ simulation predicts a TWENTY-FIVE percent reduction in carbon dioxide emissions. Plus, travel SPEEDS could increase by TWENTY percent! 

Their eco-friendlier navigation strategy for self-driving vehicles reduces fuel usage AND travel time. Instead of seeing red, with their method we can SEE GREEN much more often!

Say helloooo to my lean- GREEN- driving machine!
