311 Service Requests - Pot Holes Reported - Historical

As described in https://data.cityofchicago.org/stories/s/311-Dataset-Changes-12-11-2018/d7nq-5g7t, the function of this dataset was replaced by https://data.cityofchicago.org/d/v6vf-nfxy. This dataset is historical-only.

The Chicago Department of Transportation (CDOT) oversees the patching of potholes on over 4,000 miles of arterial and residential streets in Chicago. CDOT receives reports of potholes through the 311 call center and uses a computerized mapping and tracking system to identify pothole locations and efficiently schedule crews. One call to 311 can generate multiple pothole repairs. When a crew arrives to repair a 311 pothole, it fills all the other potholes within the block. Pothole repairs are generally completed within 7 days from the first report of a pothole to 311. Weather conditions, particularly frigid temps and precipitation, influence how long a repair takes. On days when weather is cooperative and there is no precipitation, crews can fill several thousand potholes.

If a previous request is already open for a buffer of 4 addresses the request is given the status of "Duplicate (Open)". For example, if there is an existing CSR for 6535 N Western and a new request is received for 6531 N Western (which is within four addresses of the original CSR) then the new request is given a status of "Duplicate (Open)".

Once the street is repaired, the status in CSR will read “Completed” for the original request and "Duplicate (Closed)" for any duplicate requests. A service request also receives the status of “Completed” when the reported address is inspected but no potholes are found or have already been filled. If another issue is found with the street, such as a “cave-in” or “failed utility cut”, then it is directed to the appropriate department or contractor.

如https://data.cityofchicago.org/stories/s/311-Dataset-Changes-12-11-2018/d7nq-5g7t所述，该数据集的功能已被https://data.cityofchicago.org/d/v6vf-nfxy所取代。本数据集仅包含历史数据。

芝加哥交通部（CDOT）负责监管芝加哥4,000多英里主要街道和住宅街道的坑洼修补工作。CDOT通过311呼叫中心接收坑洼报告，并利用计算机化地图和跟踪系统来识别坑洼位置，并高效地调度施工队伍。一个311呼叫可以触发多个坑洼修补请求。当施工队伍到达311报告的坑洼进行修补时，会同时填补该街区内的所有其他坑洼。坑洼修补通常在首次向311报告坑洼后的7天内完成。天气条件，尤其是极端低温和降水，会影响修补所需的时间。在天气晴朗且无降水的情况下，施工队伍一天内可以填补数千个坑洼。

如果先前请求已经为4个地址的缓冲区开放，则该请求将获得“重复（开放）”的状态。例如，如果6535 N Western已有现有客户服务请求（CSR），而收到的新请求为6531 N Western（距离原始CSR四个地址之内），则新请求将被标记为“重复（开放）”。

一旦街道修复完毕，CSR中的状态将显示为“完成”针对原始请求，以及“重复（关闭）”针对任何重复请求。当检查报告的地址时，如果没有发现坑洼或坑洼已被填补，服务请求也将获得“完成”状态。如果街道出现其他问题，如“坍塌”或“失效的公用事业切割”，则将问题转交给相应的部门或承包商。
