Pennsylvania not following California on lane changes for self-driving vehicles
California often is seen as the vanguard of national trends, from policy to entertainment, but Pennsylvania isn't following the Golden State's move to modify roadways for self-driving vehicles.
The California Department of Transportation, Caltrans, is increasing the size of lane lines from 4 inches to 6 inches to help self-driving cars read the road.
Self-driving cars use cameras to follow lane lines, “so that puts the onus on us to make sure that delineation is very clear and discernible,” Malcolm Dougherty, Caltrans director, told Pasadena, Calif.-based KPCC radio .
Caltrans also is moving away from its long-time use of “Botts' Dots” — slightly raised pavement markers used throughout the state to delineate traffic lanes, named for Caltrans engineer Dr. Elbert Dysart Botts. Dougherty said self-driving vehicles can't read them as easily as painted lines.
“Regarding changing line paint width for Highly Automated Vehicles, we have not taken such a step here in Pennsylvania,” said PennDOT spokesman Rich Kirkpatrick.
No worries. Pittsburgh is clearly positioned as a leader of the self-driving car movement .
Sorry, San Francisco.
