"Based on data collected since the installation in August of 2024, all signs point to a much safer street: The number of private vehicles misusing the bus-only lane is down by 83%! The measured "85% percentile" speed of cars that do enter the bus lane is down from 40mph to just under 30mph, while the general travel lane now matches the posted speed limit of 25mph "
"Drivers used the uncongested bus-only lane to speed in front of other traffic. These drivers often traveled at high speeds for several blocks at a time, running red lights and endangering others on the street. Drivers used the left turn lane to jump the queue at traffic signals by accelerating rapidly from the left turn lane into the bus-only lane."
"We are not entirely out of the woods yet, but it means more of our neighbors are alive today because of these simple plastic posts and speed cushions. Speed cushions before crosswalks to slow cars who are misusing the bus-only lanes. Vertical dividers between travel lanes and bus-only lanes that make it uncomfortable for drivers to enter the bus-lane or weave between lanes at speed. Vertical dividers in the center to discourage illegal left turns and u-turns."
Data collected since August 2024 show an 83% reduction in private vehicles misusing bus-only lanes and a drop in the 85th-percentile speed in the bus lane from 40 mph to just under 30 mph. The general travel lane now matches the posted 25 mph speed. Traffic fatalities fell from 10 in 2023 to 2 in 2025, and pedestrian fatalities fell from 7 in 2023 to zero in 2025. Drivers previously exploited bus-only and left-turn lanes to speed, run red lights, and perform illegal turns. Installed measures include speed cushions, vertical dividers between lanes and center dividers, and red bus-only pavement, which reduced lane misuse and improved safety, though risks remain.
