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
