Crosswalks and signals are supposed to make walkers safe as they step off the curb, but a tragic example from New York City last month shows that pedestrian infrastructure just isn\u2019t enough when it\u2019s trumped by car-centric intersection design.<\/p>\n

On September 25th, a driver turned left from Kenmore Street onto Elizabeth Street in Manhattan and fatally struck 82-year-old Sui Leung. Like\u00a0almost half of New York walkers that get hit<\/a>, she was crossing in a crosswalk.<\/p>\n

While the motorist may be charged under a\u00a0new city law<\/a>(police\u00a0have yet to declare a verdict<\/a>), the intersection where Leung was struck will remain dangerous. This is because of something called a \u201cpermitted left turn.\u201d Often marked by a \u201cleft turn yield on green\u201d sign, it allows drivers to turn left on a regular green, meaning that pedestrians can be crossing at the same time. A study from the\u00a0Oregon Transportation Research and Education Consortium<\/a>\u00a0(OTREC) found that motorists in this kind of intersection watched oncoming cars far more than pedestrians, treating the latter as an \u201cafterthought.\u201d<\/p>\n

They take their cue from planners. Between bike lanes that stop suddenly, filtering riders into traffic, and pedestrian signals that run concurrently with fast-turning cars, intersections are too often built first for vehicles; second, third, fourth and 10th for everyone else. But what if they weren\u2019t? What if designers could actually create a modal melting pot that equated walkers with those behind the wheel? Here are some progressive intersection designs that go beyond the turn signal-and-crosswalk formula to really prioritize pedestrian safety, so that those with the least armor don\u2019t become an afterthought.<\/p>\n

Protected Left Turns<\/h3>\n

According to the New York City\u00a0Department of Transportation<\/a>, left turns are a leading cause of pedestrian death, outnumbering right-turn crashes 3-1. Meanwhile, the team of researchers with\u00a0OTREC\u00a0found that left-turning drivers are especially distracted when they don\u2019t have \u201cprotected left turns,\u201d usually marked by a green arrow. And the same general, green-light free-for-all that has them watching the road also allows pedestrians to cross, creating a deadly mix.<\/p>\n

That small green arrow, a relatively quick and inexpensive fix, could save lives. But as theOSU\u00a0team pointed out, making left-turners yield is a potential time-saver, which is no doubt why it\u2019s common practice in many states. According to lead researcher David Hurwitz, however, \u201c[s]ometimes the goal of safety has to override the goal of efficiency, and we think this is one of those times.\u201d<\/p>\n

Pedestrian Head Starts<\/h3>\n

Allowing an interval of pedestrian walk time before motorists\u2019 signal change is another relatively easy adjustment. It gives walkers a head start while also reducing \u201cconflicts between pedestrians and turning vehicles and makes crossing pedestrians more visible,\u201d according to\u00a0America Walks<\/a>.\u00a0Safe Routes to School<\/a>\u00a0suggests \u201cNo Turn on Red\u201d signs to accompany the modified signal timing, creating a brief walkers-only zone in the crosswalk.<\/p>\n

Raised Crossings and Intersections<\/h3>\n

These speed-bump-like platforms ramp up crosswalks or even whole intersections. The latter, according to the\u00a0UNC\u2019s Highway Safety Research Center<\/a>\u00a0is \u201cessentially a speed table for the entire intersection.\u201d The infrastructure works two ways: It literally boosts pedestrians in the motorist\u2019s perspective by making them taller and it also slows cars down.\u00a0One intersection<\/a>\u00a0in Phoenix, Arizona, has \u201cbollards\u201d (permanent cement traffic cones) around the sidewalks, which are level with the raised-up streets.<\/p>\n

Neckdowns<\/h3>\n

Neckdowns extend the curb out into the intersection (thus their less poetic term, curb extensions), contracting the amount of street space pedestrians have to cross. According to the\u00a0Project for Public Spaces<\/a>, they increase safety for slower pedestrians, like small children and the elderly. Because curbs are usually built in a large bulb shape, they also slow turning drivers down, according to the\u00a0Federal Highway Administration<\/a>.<\/p>\n

Protected Intersections<\/h3>\n

Designed to extend protected bike lanes into the intersection, these crossings benefit pedestrians too. Alta Planning + Design\u2019s Nick Falbo modeled\u00a0the blueprints<\/a>\u00a0on Dutch infrastructure, so of course they prioritize walkers and bikers. One key design element is the \u201ccorner refuge island,\u201d which is a bit like a neckdown but with a bike lane running through its center. This island forces drivers to turn a full 90 degrees before hitting a crosswalk when making a right turn and makes the intersection smaller overall, shrinking the distance pedestrians, as well as bikers, have to traverse.<\/p>\n

The Barnes Dance<\/h3>\n

Named for traffic engineer Henry Barnes, not a do-si-do, the Barnes Dance (also called a pedestrian scramble) restricts right turns on red, and turns the whole intersection into a walkers-only zone for the length of a long signal. In a Chicago pilot begun in 2013, drivers wait for 35 seconds\u00a0according to\u00a0CBS<\/a>. Crosswalks are often put in the shape of an X through the middle, as well as along the four corners, to designate that walkers can cross diagonally.<\/p>\n
