311 Service Requests - Street Lights - All Out - 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.

All open reports of "Street Lights - All Out" (an outage of 3 or more lights) made to 311 and all requests completed since January 1, 2011.The Chicago Department of Transportation (CDOT) oversees approximately 250,000 street lights that illuminate arterial and residential streets in Chicago. CDOT performs repairs and bulb replacements in response to residents’ reports of street light outages.

Whenever CDOT receives a report of an “All Out” the electrician assigned to make the repair looks at all the lights in that circuit (each circuit has 8-16 lights) to make sure that they are all working properly. If a second request of lights out in the same circuit is made within four calendar days of the original request, the newest request is automatically given the status of “Duplicate (Open).” Since CDOT's electrician will be looking at all the lights in a circuit to verify that they are all working, any “Duplicate (Open)” address will automatically be observed and repaired.

Once the street lights are 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 lights are inspected but found to be in good repair and functioning; when the service request is for a non-existent address; or when the lights are maintained by a contractor. Data is updated daily.

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

该数据集涵盖了自2011年1月1日起至报告时止，所有向311服务台报告的“街灯全部熄灭”情况（即3盏或以上街灯故障）以及所有完成的请求。芝加哥交通部（CDOT）负责监管约25万盏照亮芝加哥干道和住宅街道的街灯。CDOT根据居民对街灯故障的报告进行维修和灯泡更换。

每当CDOT接到“全部熄灭”的报告时，负责维修的电工将对该回路中的所有街灯（每个回路有8-16盏灯）进行检查，以确保它们均能正常工作。如果自原始请求之日起四个日历日内，同一回路内再次报告灯泡熄灭，则最新的请求将自动被标记为“重复（开放）”。由于CDOT的电工将检查回路中的所有街灯以验证其工作状态，因此任何“重复（开放）”地址将自动被观察到并进行维修。

一旦街灯修复完成，CSR中的状态将显示为“完成”对应原始请求，以及“重复（关闭）”对应任何重复请求。当报告的灯泡经检查发现处于良好状态且功能正常；或者服务请求针对的是不存在地址；或者灯泡由承包商维护时，服务请求的状态也将更新为“完成”。数据每日更新。
