The deadly 85th Percentile Rule has gone mainstream.
Credit the LA Times’ Laura Nelson for interrupting the paper’s move to El Segundo with a front page story explaining how and why speeds are set at the speed of the 15th fastest driver on the street — the 85th percentile of drivers.
To update driver speeds, city engineers visit a street in the late morning or early afternoon, park along a stretch of road without stop signs or traffic lights, and use an electronic device to measure the speeds of 100 drivers.
They rank the speeds from fastest to slowest and identify the 85th percentile — that is, the speed just below the 15th-fastest driver. City engineers use that “critical speed” as a basis for establishing a new speed limit, typically rounded to the nearest 5 mph.
Which means drivers can set the speeds with their right foots. Which is kind of like putting bank robbers in charge of security at Wells Fargo.
Although that might be an improvement over their recent scandals, but still.
Failing to conduct those surveys, or raise speeds as a result, means police officers are prohibited from using speed guns or other electronic devices to stop speeders.
And drivers can go as fast as traffic and LA’s over-engineered streets will allow.
The restrictions on police using electronic devices has coincided with a 77% drop in the number of speeding tickets written annually by the Los Angeles Police Department, from 99,333 in 2010 to 22,783 last year.
Traffic officers have been particularly hamstrung in the San Fernando Valley, where the majority of the city’s speeding tickets are written and more than 130 miles of streets carry speed enforcement restrictions, according to a Times analysis of city data.
“People are driving like maniacs on city streets,” said Dennis Zine, a former city councilman in the Valley who worked as a traffic officer. “It’s costing people their lives.”
Particularly the lives of bike riders and pedestrians.
There have been numerous failed attempts to reform the 85th Percentile Law, each dying in the legislature over fears that speeding drivers will have to slow down or get the tickets they deserve.
Which is kind of the point.
Maybe this story will finally motivate homeowners to join with bicycle and pedestrian advocate, to demand that state legislators change the law that imposes highway speeds on city streets.
And leaves far too many bodies in its wake.
Thanks to David Drexler for the heads-up.
