Monthly street lights & signals requests

How many street lights & signals 311 requests Chicago residents file each month.

How this category is defined

What counts as street lights & signals: Broken street lights, outages, damaged signs, and malfunctioning traffic signals or pedestrian crossings.

In Chicago’s raw 311 data, the following 6 service_type values are counted as street lights & signals:

  • Alley Light Out Complaint
  • Sign Repair Request - All Other Signs
  • Sign Repair Request - Stop Sign
  • Street Light Out Complaint
  • Street Light Pole Damage Complaint
  • Traffic Signal Out Complaint

To reproduce these counts against the raw feed

SELECT count(*)
FROM <chicago_311_raw>
WHERE service_type IN (
  'Alley Light Out Complaint',
  'Sign Repair Request - All Other Signs',
  'Sign Repair Request - Stop Sign',
  'Street Light Out Complaint',
  'Street Light Pole Damage Complaint',
  'Traffic Signal Out Complaint'
)

Analyst tip: Austin splits street lights ('AE Street Light Issue - Address') from traffic signals ('TPW - Traffic Signal - Maintenance') and signs ('TPW - Traffic Sign Maintenance'). Calgary uses the 'Roads -' prefix for all three. Oakland uses the terse 'ELECTRICAL' and 'TRAFFIC_ENGIN' abbreviations.
