Estimate amount of people
Estimate how many people live in a street then you know the amount of streets
Estimate how many crossroads there are based on the streets
Estimate how many of those crossroads have traffic lights.
Did someone asked you this in a job interview?
Take 10 hours to drive in this direction at this speed and I see a light every 20m, do the quik math
I think the street even have numbers in New York so its quite easy
Take a percentage off cuz of stops and railroads or whatever
walk around and count them
Multiply X routes with Y routes and you get an avg
Well I know New York has 100 streets because I’ve heard of 1st street and I’ve heard of 84th street. I also know there are about 14 avenues. So that means about 1400 intersections. Assume each one has a traffic light, I’d assume the traffic lights on highways/freeways are negligible.
Same guy at university
No, but it's very similar to a question previously asked at a company I want to work at. (Don't want to say the company cause it seems to get an unusually small amount if applicants for the pay) Got most of them just couldn't manage this one, thanks.
If it's a job interview question just say a random estimate like 232 there's a 100% chance they dont even know the answer
232 trafic lights in New York? Are you retarded?
Multiply that by 10 and you are geting close
Call the NYCDOT and ask them.
