Caltrans changing road striping (delineation standards) to 6 inches to facilitate automated vehicles

From Clean Technica, 25 July 2017

California’s state highway management system is now apparently one of the first systems anywhere in the world to be actively changing its operations to better suit self-driving vehicles.  Caltrans Director Malcolm Dougherty, in an interview with KPCC Southern California Public Radio, expounded on the matter like this: “The automated vehicles (AVs) can follow lane lines. They can’t follow the Botts’ Dots, so we’re actually changing our delineation standards to go away from the Botts’ Dots which we’ve been using for decades because AVs have a difficult time following those.”

“All of our lane lines are going to get thicker,” Dougherty continued, in his interview with KPCC. “Today our lane lines are only four inches thick. Now every lane line we lie down going forward is going to be six inches thick. I’ve already started to see some of this transition.”

San Francisco Business Times provides more details: “Dougherty said that the lane modification will happen as roads and highways get new construction or standard re-striping done — and added that the agency aims to have the state’s highways and interstates modified within the next two to three years. California has around 50,000 miles of roadways.

So, to reiterate that last point, to those now worrying about costs: the changes are mostly going to be made in conjunction with regular maintenance and construction work, rather than being a standalone matter. So, the costs of the work shouldn’t be too expensive.

As a reminder here, there are many companies now testing self-driving vehicle tech in California, including Waymo/Google, GM, Tesla, Hyundai, Uber, and Baidu.
