What happens under the hood?An estimator of “street-block policing”
p(ticket |s, t) =∑T
t=1 ticketst∑Tt=1
∑Ss=1 ticketst
wheres street block within a precinctt time of the day (hour)
Assumptions:I scope of dataI obvious low parking locations
Scaleability
Room for expansion:I Features:
I add likelihood of car being stolenI disaggregated data unavailable from NYC Open Data
I add map of surrounding streets with low probability of ticketI add location of nearby parking lots on mapI add (email, SMS, Twitter, etc) alerts
I Geographic:I expand to other cities that deliver open data (currently 45 in
the US and expanding)
More Data patterns1-year aggregated by time of day per month (Staten Island)
Even changes in ticketing activity if broken down by month...
