Technology is increasingly becoming a part of how government can make roads safer. Dynamic lighting, glow-in-the-dark highway lines, and cars that can communicate with each other are all new technologies that may someday become common on roadways. Vehicles increasingly have more features that automate processes, with some vehicles becoming completely autonomous. And now technology is being developed that will let a car know how a driver is feeling, Phys.org reported.

Facial recognition technology being developed by the Swiss Federal Institute of Technology Lausanne's (EPFL) Transportation Center could be used to more closely integrate a car's interface with a driver's mindset and intentions. By using equipment that tracks the driver's eyes, measures eye fatigue and reads the driver's lips, researchers said they hope to develop highly interactive and intelligent vehicles.

Research, which is being conducted along with EPFL's Signal Processing 5 Laboratory (NTS5) and PSA Peugeot Citroën, is still in early stages, and researchers plan to begin real-world simulations soon.
