This is a Temporary Traffic Signal Plan prepared by the City of Los Angeles Department of Transportation (LADOT) for the Brighton to Roxford Double Track Project, Segment 4, specifically for the Polk Street and San Fernando Road at-grade crossing improvements. The plan details the installation of a new ATSAC 2070 traffic signal controller in a 352 cabinet, video detection camera systems, new traffic signal heads, pedestrian signal equipment, and associated electrical infrastructure. The project involves semi-actuated traffic signal operation with camera detection at the Polk Street and San Fernando Road intersection, with specific phase diagrams and signal timing configurations documented. The temporary phase diagram indicates eight operational phases with various vehicle and pedestrian signal movements, along with railroad preemption capability. The plan specifies installation of new wood poles with 11 to 13-foot embedments, mast arm standards, and comprehensive conductor schedules for all signal runs and auxiliary equipment. Contractors are required to notify LADOT's Traffic Signal Inspector five working days before construction begins, with full restoration of the ATSAC system required within five working days after system shutdown.

The plan establishes specific operational requirements including the maintenance of regular traffic signal control from 6:00 a.m. to 9:00 a.m. and 3:00 p.m. to 7:00 p.m. on weekdays except national holidays, with signal deactivation and activation performed only by LADOT electricians upon 24-hour advance notice. Contractors must arrange material pickups and returns through LADOT's designated divisions, with traffic signal controllers requiring 30 working days advance notice. All traffic signal equipment supplied by contractors shall be new, with vehicle head equipment utilizing 1.5-inch diameter pipe fit mounting hardware. The plan references LADOT's Special Provisions and Standard Drawings (Red Book) for traffic signal installation and the City of Los Angeles Board of Public Works Standard Specifications as the governing construction standards. Existing traffic control signing must be maintained by the contractor, with damaged or lost signs replaced at the contractor's expense, and large street name signs relocated from vertical poles to mast arms per LADOT standards.
