The jam Google Maps saw first

Riya ki flight mein sirf ek ghanta bacha tha. Sadak bilkul khaali dikh rahi thi, par Google Maps ne bataya ki aage 12 minute ka jam hai. Road par na koi camera tha, na koi sensor. Toh Maps ko pata kaise chala?

Case 02 ka sach: Clue 1, phones: jo log navigation chala rahe hain, unke phones ka anonymous location data Maps ko batata hai ki gaadiyan kitni tez chal rahi hain. Jab ek hi sadak par bahut saare phones ek saath dheere ho jaate hain, toh wahan jam hai. Clue 2, bheed aur purana record: ek phone ke rukne se kuch nahi badalta, kyunki Maps poori bheed ki speed dekhta hai. Saath mein wo har sadak ka purana traffic pattern bhi milata hai. Clue 3, network: Maps ke liye shehar chauraho aur sadakon ka ek network hai, aur wo raasta minute ke hisaab se chunta hai, kilometre ke hisaab se nahi.

Tip: agli baar jab Maps do raaste dikhaye, toh kilometre nahi, minute dekhna.
