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.
