Pennsylvania DOT recently won a $8.4 million dollar grant from FHWA to begin testing autonomous vehicles in work zones. The story by Ed Blazina ran last Wednesday in the Pittsburg Post-Gazette. And he shows a real understanding of the problem when he writes, “one driving circumstance that almost all of the companies have avoided so far is driving through work zones. That’s because those areas don’t provide the regular pattern self-driving vehicles thrive on and have out-of-the-norm items such as construction barrels and lane markings that aren’t as distinctive as on regular roads.”
The award was the largest of eight grants handed out by Secretary Chao to study the safety of autonomous vehicles. This is significant as it demonstrates recognition of the importance of work zone safety at the highest levels at DOT.
PennDOT doesn’t believe any one solution will solve the problem. So, they proposed to approach the problem from a variety of angles including, “detailed mapping systems, communications systems between work-zone equipment and self-driving vehicles, and coatings for barrels and road surfaces to help self-driving vehicles recognize conditions.”
The story made no mention of automated work zone reporting, but that may be part of the “communications…between work-zone equipment and self-driving vehicles.”
In their 25 page application PennDOT stated they will start with computer simulations then move to a closed track for the second phase of testing. Once their concepts are proven they will then test them out in real-world work zones.
They will be working with a nine member team including Carnegie Mellon and PPG Paints.
