aCITY OF SANTA ANA PROJECT DESCRIPTION AND BACKGROUND The project area includes 19 signalized intersections owned and operated by City of Santa Ana along McFadden Avenue from Harbor Boulevard to Grand Avenue, as listed in Table 1: Project Intersections. City of Santa Ana has made significant investments in the signal infrastructure to enable the communication between the signalized intersections to the Traffic Management Center (TMC). The controllers along the corridor are Econolite 2070 with ASC/3 firmware or Econolite Cobalt with EOS firmware controller in Type 332 or NEMA Type P Cabinets and communicate back the TMC via Fiber Optic or Twisted Pair Communication. The traffic signals are operated utilizing Econolite's Centracs Advanced Traffic Management System (ATMS). The active transportation project currently under construction will replace all the controllers with Econolite Cobalt ATC Controllers with EOS firmware, upgrade all communication to Fiber Optic communication, and upgrade the current loop detection to Video Detection Systems at all 19 intersections.

OCTA's Route 66 bus line through McFadden Avenue operates on approximately 10-minute headways during the peak periods and 20 minutes during off-peak periods with approximately 39 bus stops, as shown in Figure 1 below. The OCTA buses along Bus Route 66 host a suite of equipment that allows for comprehensive data collection, remote network communications, and location tracking that exchange information between the bus operator and the OCTA Traffic Operation Center (TOC). Each bus is equipped with a Cradlepoint router (IBR1100 or IBR1700) with cellular connection to the OCTA's Conduent OrbCAD Computer-Aided Dispatch/Automatic Vehicle Location (CAD/AVL) system. Bus locations are polled by the OrbCAD system and uploads the General Transit Feed Specification (GTFS) package to the Swiftly data engine roughly every ten (10) seconds. This level of location tracking and schedule status is often sufficient to support priority service systems, like centralized and/or cloud-based transit signal priority (TSP) systems, that ingest this information to make informed priority requests to other traffic systems. 2
