This dataset contains the street sweeping schedule for 2016. Public Works mechanically sweeps each street in Cambridge once per month, April through December (weather permitting). Signs are posted on each residential street indicating the schedule, which differs by city district and street side. In order to ensure that streets are properly cleaned, cars must move off the side of the street being swept to avoid being ticketed and towed. The Cambridge Open Data portal contains a related dataset called Street Sweeping Districts, which is a polygon layer illustrating the districts on a map. That dataset is available here: https://data.cambridgema.gov/Geographic-Information-GIS-/Street-Sweeping-Districts/upm7-2w6p.
