Traffic Analysis and Collision Pattern ( Vision Zero) 

This analysis will primarily focus on the number of collisions before and after NYC adopting  Vision Zero. In this analysis, the statistical model of K-S testing will be used to compare the two periods;  before and after the adoption of Vision Zero. The study will include a time series of the effectiveness of Vision Zero using the data; based on the cumulative number of accidents. The cumulative number and daily pattern of the collisions will measure probabilities of effectiveness.
