The Simple Solution to Traffic

The way we can make traffic disappear.

stuck at an intersection you always watch unfold the fundamental problem of


traffic on green the first car accelerates and then the next and then


the next and then the next and then you only to catch the red had the cars


accelerated simultaneously you would have made it through coordination not


cars is the problem because we are monkey drivers with slow reaction times


and short attention spans


even if we tried getting everyone to press the pedal on 321 now would be


challenging this disc ordination limits how many cars can get through an


intersection and when one backs up to the next that’s when city-sized gridlock


cascades happen taking forever to clear in general more intersections equals


more dis coordination which equals more traffic this is the motive behind big


highways no intersections splits and merges yes intersections no no stopping


no coordination problems no traffic


well that’s the theory anyway intersections outside of a highway will


back up onto it again because human reaction times limit how many cars can


escape the off-ramp when the light changes but even without intersections


there would still be traffic on the highway traffic can just appear take a


one lane highway with happy cars flowing until a chicken crosses the road the


driver who sees it breaks a little the driver behind him doesn’t notice


immediately and brakes a little harder than necessary the driver behind him


does the same until someone comes to a complete stop and oh look cars


approaching at highway speeds must now stop as well though the chicken is long


gone it left a phantom intersection on the highway


this is what happened when you’re stuck in traffic for hours thinking there must


be a deadly pile up ahead and then suddenly the traffic’s over with no


wreckage insight to your relief if you’re a good person and mild annoyance


if you aren’t you just pass through a phantom intersection the cause of which


is long gone and this phantom intersection moves it’s really a traffic


snake slithering down the road eating oncoming cars at one end and pooping


them out the other on a ring road a single car slowing down we’ll start a


roberts of traffic that will last forever even though there’s no problem


with the road if the drivers could coordinate to accelerate and separate


simultaneously easy driving would return but they can’t so traffic eternal on


highways traffic snakes grow if cars are heated faster than excreted and they


Frank if excreted faster than eat it dying when the last car accelerates away


before the next car must stop now in multi-lane highways there needs be no


chicken to start gridlock a driver crossing lanes quickly with cars to


close behind is enough to birth the traffic snake that lives for hours and


leads its this quick crossing the causes drivers behind to over break and begin a


chain reaction but we can make traffic snakes less likely by changing the way


we drive your goal as a driver is to stay the same distance from the car


ahead is from the car behind at all times


tailgating is trouble not just because it makes accidents more likely but


because you as the tailgater can start a traffic snake if the driver ahead breaks


always in the middle


this gives you the most time to prevent over-braking but also gives the driver


behind you the most time as well and when stuck in traffic this rule would


get all cars to pull apart the snake faster


that’s the simple solution to traffic getting humans to change their behavior


perhaps by sharing this video to show how and why traffic happens why


tailgaters are troubled and how we can work together to make the roads better


for all the end except yeah


wishing upon a star that people are better than they are is a terrible


solution every time instead what works as a structurally systematized solution


which is exactly what self-driving cars are self-driving cars can just be


programmed to stay in the middle and accelerate simultaneously they’ll just


do it the more self-driving cars and an intersection of the more efficient the


intersection get a solid lane of self-driving cars vastly increases


throughput hmm actually if you been humans from the road which we should


totally do any way you can get rid of the intersection entirely after all a


traffic light is just a tool for drivers on one road to communicate with drivers


on another poorly in coarsely red equals don’t go now we are coming through the


intersection green equals good to go but self-driving cars can talk to each other


at the speed of light with that kind of coordination no traffic light necessary


just as with the highway the best intersection is no intersection humans


will never drive this precisely at the intersection the fundamental problem


with traffic that you watch unfold as well


everything is people so the real simple solution to traffic is no more monkeys
