From the above figure, we see that the point of change (indicated by the peak) does not correspond to the Vision Zero Adoption Date. This seems to indicate that the Vision Zero Adoption date was not directly responsible for the increase in the rate of daily accidents.
Conclusion
In conclusion, the KS-test indicates an increase in the rate of daily accidents after NYC date of adoption to Vision Zero. The point of change analysis points that the increase in the rate of accidents does not coincide with the Vision Zero implementation date. However, it is difficult to conclude that the implemented policies of Vision Zero were not adequate.   
Furthermore, we could presume that they are other factors involved that contribute to the increase in the rate of daily accidents. More and more, the drawn conclusion is that Vision Zero's adoption did not result in a decrease in the rate of accidents as expected. On the contrary, there is an increase in accident; according to the point of change, the policy implementation date does not contribute to the increase.
