***This dataset has been deprecated. Cambridge now maintains a single Computer Aided Dispatch open dataset that includes data from multiple years, including 2015.

The Computer Aided Dispatch (CAD) Entries data set reflects information approved for general release by the Cambridge Police Department and the Cambridge Fire Department. All entries are inputted by dispatchers in the Emergency Communications Center (ECC). This data set does not reflect all events received by the ECC. Certain entries are not included due to concerns related to privacy, criminal investigation, or protected data. Additionally, not all entries reflect a dispatched response and some data may reflect a duplicate entry for a specific incident. This dataset does not include any first responder calls related to emergency medical services (EMS), and does not contain all police or fire entries.

This point layer is are all of the Cobrahead street lights which will be replaced throughout the summer of 2014. There are other types of lights in the City which are not included in this GIS layer. Decorative street lights which will be replaced in 2015, and lights owned by others (DCR, Universities, & private) have not been verified for accuracy yet and will be included in a future update of this layer.

This dataset contains a list of both Residential Parking Permits and Visitor Parking Permits. The Traffic, Parking and Transportation Department’s Permit Year spans from November 1st through October 31st of the following year. The Parking Permit renewal period spans from November 1st through January 31st of the following year. This dataset will be updated semi-annually at the end of the Permit Year, and at the end of the Parking Permit renewal period, to provide users with updated information from before and after permit renewals occur. This dataset currently includes permit data for the entirety of 2017 and through January 31 of the 2018 permit year.

The dataset identifies the Census Block that each parking permit is located in.

The first person that applies for a Resident Parking Permit will automatically receive that household’s single Visitor Parking Permit with their Resident Permit. For households without a vehicle or those who only require a Visitor Parking Permit, the associated fee is $25.00, except for Senior Residents (age 65 or older) or persons with disabilities.

The Account Number field is associated with the first resident in a household who applied for either a Resident Parking Permit or a Visitor Parking Permit. If the resident applied for a Resident Parking Permit they should have an associated Visitor Parking Permit with the same Account Number.

Each permit is characterized by a permit type. The permit types in this dataset include:

A1: Standard Cambridge residential parking permit.
A2: Replacement residential permit.
A3: Senior resident permit.
G1: Visitor permit, no resident permit.
G2: Visitor permit with Resident Permit.
G3: Senior Visitor Permit Only.

A Senior Resident could have both an A3 and G3 permit, or just a G3 permit.

Resident Parking Permits allow Cambridge residents to park their vehicles, including motorcycles, in locations throughout the City posted "Parking by Permit Only". The purpose of the City's Resident Parking regulation is to maximize the availability of parking for Cambridge residents while discouraging long-term parking on residential streets near commercially zoned areas or transportation access points.

Visitor Parking Permits are provided to Cambridge residents for use by their guests to park near the residents’ homes. When placed on the dashboard, it may be used for up to three consecutive days in locations signed as “Parking by Permit Only” in the geographic area shown on the map on the back of the visitor permits or here on the Traffic and Parking Department’s website. http://www.cambridgema.gov/traffic/Permits/visitorparkingpermits/visitorparkingmap

Non-emergency service requests submitted through Cambridge's Commonwealth Connect application powered by SeeClickFix Open311.

Please note that the City of Cambridge uses Commonwealth Connect to track both public and internal work orders. Occasionally, a ticket will change from internal to public, or vice-versa. All tickets that originated as public requests are included in this dataset. However, technical constraints prevent us from displaying information for tickets that originated as internal work orders.

Prior to using Commonwealth Connect, the City utilized iReport. Three open datasets derive from historical iReport data:
-Pothole Repair Requests (https://data.cambridgema.gov/Public-Works/Pothole-Repair-Requests/h2y4-rf5c)
-Graffiti Cleanup Requests (https://data.cambridgema.gov/Public-Works/Graffiti-Clean-Up-Requests/hk2d-8z9b)
-Unshoveled/Icy Sidewalk Complaints (https://data.cambridgema.gov/Public-Works/Unshoveled-Icy-Sidewalk-Complaints/72bt-ct3c)
-Snow/Ice Sidewalk Ordinance Violations (https://data.cambridgema.gov/Public-Works/Snow-Ice-Sidewalk-Ordinance-Violations/q8b2-58ab)

This dataset contains the Average Daily Traffic counts and AM and PM peak hour Traffic counts measured on various road segments in the City of Cambridge from 1972 to 2017. The counts in this data set reflect only vehicle counts. An Average Daily Count measures the number of vehicles for an entire day, or an average of several days. Automatic Traffic Recorders (ATRs) log every vehicle that passes in each direction and this data is used to calculate Average Daily Traffic volumes and AM and PM Peak Hour Traffic Volumes for the street. The Peak Hour is average highest number of vehicles recorded during the morning and evening peak hour. Not all streets have the same peak hour. For example, the peak hour for one street could be 5 pm to 6 pm, whereas a peak hour for another street could be from 5:15 pm to 6:15 pm. The peak hour for a street can also change from day to day. When counts are done for several days, the Peak Hour count is the average of the highest peak hour over those days.
Automatic Traffic Recorders (ATR’s) are rubber hoses temporarily affixed to the street. When a vehicle passes, a pulse of air passes through the hose and triggers an air switch in a recording device on the roadside. The recorder device is a small steel box powered by a battery. Air switch triggers are stored on board and later downloaded to a computer. Note: Traditional and older ATRs were not able to record bicycles, however, more recent ATR’s (past 5 to 10 years) have been able to record bicycles that pass over the recorder.
