America’s roads are a few of the most harmful within the developed world. Almost 43,000 folks die in site visitors accidents every year within the U.S., a quantity that has continued to rise even whereas different high-income nations have seen site visitors fatalities fall. Greater than 7,500 pedestrians have been killed in America in 2022, probably the most since 1981. That works out to about 20 folks every day.

However not each metropolis sees such optimistic outcomes. Los Angeles, Seattle, Portland, Austin, Washington, D.C. have all seen site visitors deaths stay stubbornly excessive within the years since signing on to Imaginative and prescient Zero. Why are some cities succeeding the place others aren’t? Consultants share a couple of greatest practices gleaned from communities the place the Imaginative and prescient Zero program has labored.
Make intersections safer
More than half of the crashes that end in loss of life or critical damage occur round intersections, so enhancing security at crossroads ought to be a precedence. A technique cities can do that is by eradicating parking spots inside 20 or 30 ft of intersections, in any other case referred to as “daylighting.” This improves sight-line visibility for each drivers and pedestrians.
“At a typical intersection, you might have loads occurring there,” says Leah Shahum, founder and director of the Imaginative and prescient Zero Community. “Ideally everybody would see one another completely and wait their flip, however sadly numerous occasions the visibility is actually obstructed. That is significantly the case as vehicles get larger.”
Certainly, People love large vehicles. SUVs accounted for more than half of recent automobile gross sales final 12 months, and the case of the unimaginable increasing automobile is exacerbated by the rise of EVs, which have heavier batteries that necessitate bigger tires and frames.

Some cities use paint to sign to drivers that they will’t park close to intersections, however this doesn’t all the time work. “Vehicles are sort of like gasoline,” says Mike McGinn, government director of the pedestrian advocacy group America Walks and the previous mayor of Seattle. “They increase to fill the amount allotted to them. For those who don’t bodily forestall them from occupying the area, they may.”
Bodily limitations are simpler. Planters, bushes, and bike storage can be utilized to fill area between the curb and the highway and block vehicles from parking close to the intersection. These “curb bulbs” are dearer than portray and may take longer to construct, but when a metropolis is feeling strapped for money or time, it could actually go for a “quick build” — a brief barrier product of low-cost supplies like plastic bollards or transportable planters.
These can be utilized in areas the place officers need to pilot a possible curb bulb earlier than making it everlasting. Such pilot tasks will help fight group pushback, which each Shahum and McGinn say is the primary barrier to daylighting initiatives. “You’ve by no means seen folks so mad at a group assembly as once you inform them they could lose parking,” Shahum says. “Generally an illustration venture can actually assist folks see with their very own eyes and expertise for themselves what the change will probably be like. You may take away these parking spots, you’ll be able to add some short-term bodily options there, after which see what folks assume.”

Deliver down speeds
Enhancing intersection visibility is necessary, however “daylighting alone isn’t gonna clear up your drawback,” says McGinn.
Crucially, Fremont, Hoboken, and New York all lowered velocity limits citywide, and that is seen as the only most necessary consider lowering site visitors deaths. However other than altering the numbers on velocity restrict indicators, there are savvy design instruments that may sluggish drivers down. Narrowing lanes from 13 ft large to 10 ft, for instance, can create what McGinn calls “psychological friction.” With much less room to maneuver, drivers are inclined to go slower than they’d in wider lanes, normally to guard their very own vehicles however with the knock-on impact of being safer for close by pedestrians, too.
New York has been testing “clever velocity help” (ISA) know-how that limits velocity on the town’s automobile fleet. In Europe, all new light-duty automobiles should have ISA capabilities, and the Nationwide Transportation Security Board wants to roll out the same rule within the U.S.
Take into consideration the large image
Cities ought to keep away from making piecemeal adjustments to streets and as a substitute making an attempt to herald holistic enhancements, says Shahum. It’s regular to need to change the velocity restrict or repair an intersection on a “drawback” road that skilled a high-profile site visitors fatality, however “you possibly can step again and scan the entire metropolis and ask, ‘The place does this identical bodily state of affairs exist even when we haven’t had a extreme crash there?’ We need to take a extra proactive and predictive method to highway security.”
It helps, too, if a metropolis has “extra to work with to start with,” says McGinn. Hoboken had “an older road grid, slender streets. Hoboken could have a bonus as a result of many extra individuals are in reality strolling and utilizing transit and recognize the adjustments.”
In some ways, Imaginative and prescient Zero cities are preventing an uphill battle to prioritize security in a car-centric society. Autos are getting bigger and even faster. Drivers are extra distracted. We proceed to design for speed and convenience. “These cities are attempting to vary 100 years of road and automobile design and coverage, and it’s going take some time to actually change the circumstances we’ve created which might be simply wildly unsafe for folks,” Shahum says. “We’re solely going to be as protected because the atmosphere permits us to be.”
