The Traffic, Parking, and Transportation has a series of data sets available to the general public on our Department's section of the City's Open Data web site. We are in the process of adding new information. So far you can download the following data sets:

Permanent Count Station. The Street Management Division installed traffic counting equipment on Hampshire Street at Portland Street in the Fall of 2013. The station counts both vehicles and bicycles in each direction on Hampshire Street. 

Parking Tickets. This layer contains the Parking Tickets issued between January 1, 2014 and March 31, 2014 and contains tickets that were issued by both the Parking Control Officers (PCOs), and the Cambridge Police.

If there is any data that you would like to see included, please contact us here.
