If you have ever witnessed first-hand the glorious vehicular chaos that is dropping off or picking up someone up at a major airport terminal, you may have wondered that yourself.
This video of LAX illustrates nicely just how many moving parts there are all around at an airport drop off.
I make this modern day Death Star trench run 4+ times a day driving for Uber, depositing bleary-eyed travelers of the night to the check-in spots for their red eye flights. From a purely transportation planning point of view, the MSP Terminal 1 drop off corridor has all the elements to be a giant game of Human Frogger. Four lanes, any of which can quickly change between travel and parking lanes, cars zigzagging in and out through any opening they can find, and scores of people popping abruptly from cars and sleepily stumbling across the lanes, their minds fixed on getting through check-in and mentally preparing for the body scan. All of this takes place with no traffic control and hardly any traffic signs.
Yet, with all this close quarters movement of people and cars, in my 100+ visits at peak travel time late at night, I have yet to see as much as a fender-bender, let alone a pedestrian strike or major accident. How is this possible? How is there not an ambulance permanently posted on site where they stick the rookie EMTs because, “If they can witness the constant carnage and still keep their nerve, they can handle anything”?
I have a theory about how this paradox can function, and I think planners could learn a thing or two about planning urban streets. As I see it, there are 3 critical elements to this equation.
- Speeds are slow
At 15 miles per hour, the speed limit in this area, there is enough time for drivers and pedestrians to process the chaos and confusion around them and avoid accidents. And yet, even at this slow speed, everything still moves along smoothly, people get where they need to go and move along without incident. On a related note, if there were collisions at this speed, the chances of pedestrian deaths would be very low. As this study shows, at even 20 mph, fatalities are quite low. Compare that to just 10 mph faster, at 30 mph pedestrian fatalities are nearly half of all incidents. Food for thought when posted speed limits and/or operating speeds in even the densest parts of cities is often 30 mph.
- Pedestrians and drivers must constantly communicate
Without traffic signals, people directing traffic, or even much signage to give guidance, one might assume that the system would face gridlock on an almost perpetual basis. But, quite the opposite is true. Without formal direction, people must rely on one another to signal intentions. This means people are more alert and directly focused on others moving around them.
- Danger is expected
This one is a little counterintuative, but I am guessing, dear reader, that at some point you have driven in an area where pedestrians often wander into the street without warning. Maybe it was an area with a lot of bars where drunks shuffle into the streets with as much grace and self awareness as the walking dead, maybe it was in a neighborhood with a lot of immigrants from a land where the car has not yet claimed dominion over the streets. Whatever it was, I want you to think about how your driving changed. Were you more aware of pedestrians? Were you more on edge, ready to slam on your breaks in a split second? It may have been annoying to you, but I guarantee that your hyper alertness was much better for pedestrian safety. Here’s a nice article with links to academic sources that backs up that claim. In short, as a driver if you expect danger around every corner, you are more alert and able to react to sudden dangers quickly.
- Speeds are slow
Airport drop-offs are not perfect analogues for city streets; people generally move in one direction and there is not the dynamics of a city street system and its flows and cycles. However, I think the lessons are at least worth trying in urban settings. Sure, slower speed limits, less reliance on traffic control devices, and the heightened awareness brought on by pedestrians that have a greater presence and right in the streets might be annoying to drivers. But what is more important, less annoyance for drivers or far fewer pedestrian fatalities and injuries? And lest you think pedestrians accidents with cars are insignificant in this state, read this.
That’s all for this time, dear reader, until we meet again,
