An earlier version of the distance map followed the city's legal boundary out into the ocean and shaded parts of Santa Monica Bay and the harbor as if they were more than 3 miles from a dog park. The map now shows only land. None of the figures in the piece change, because every distance was measured from where people live.

An earlier version said LA Metro's escalators go 90 feet per minute. That's the speed Metro's design specifications call for, and the piece now says so. A reader measured two of Metro's newer Schindler escalators at 98.4 feet per minute, just under the American maximum, so at least some of the system runs faster than its own specification. We're asking Metro how its escalators are set.

Elberon Avenue and Gaffey Street in San Pedro, which the map ranked 448th with 138 collisions, is not an intersection. Elberon crosses above Gaffey on a bridge, and the map had been assigning every collision to the nearest named corner rather than the one written on the report. Collisions are now matched by street name. Elberon and Gaffey is gone, along with 102 dead ends that had been ranked as intersections, and six of the ten worst corners are in the San Fernando Valley rather than seven.

An earlier version overstated connecting traffic at LAX by treating every passenger the ticket survey cannot account for as someone changing planes. Connections are now counted from each ticket's routing. The 2019 figure falls from 7,146,192 to 4,258,090 and the 2024 figure from 5,369,620 to 2,751,570, so connecting traffic accounts for about 35 percent of the domestic decline rather than 41. The finding that local passengers drove the decline is unchanged.

An earlier version described Spirit Airlines' May 2026 figures as an incomplete filing. They were complete, because Spirit ceased operations on May 2 and flew for about one more day. Passenger totals and the findings built on them are unchanged.
