I often plan to go to banks, hospitals,government offices but never know how long I should wait. Sometimes I reach and it is a short wait, other times it turns into hours standing in a queue. This often disrupts other important work. If I could just check the expected wait time or rush at that place like malls on weekends or any place before leaving home I can choose better timing to go there. Google Maps tells me traffic, in the same way based on no.of mobile devices at that particular location we can track whether the place is rushed or not, soltuion on this helps long queue places like Tiurpati, voting places etc..
