(9) CITY OF SANTA ANA <br /> OCTA Existing System: The consultant shall coordinate with OCTA to survey and evaluate all existing <br /> transit equipment and operations that would be relevant to a cloud based TSP implementation. This <br /> coordination should include cybersecurity discussions with the OCTA Information Services team to <br /> ensure the proposed solution is viable within the existing environment. The consultant shall also <br /> coordinate with the OCTA Transit Planning and Bus Operations staff to collect bus operations, such as <br /> ridership, dwell time, and on-time performance for bus lines 66 along the project corridor. <br /> Field Survey: The consultant shall review the geometric layout, transit bus stop locations, at-grade rail <br /> crossings, verify and/or inventory existing traffic signal control and intelligent transportation systems (ITS) <br /> equipment, and identify any operational deficiencies for each intersection or road segment along the <br /> project corridor. The review shall include an assessment of the existing intersection lane geometry, traffic <br /> conditions, and traffic signal or ITS/telemetry control equipment along the corridor and at each <br /> intersection. Techniques utilized shall include but not be limited to visual inspection, available as-built <br /> plans, agency consultation, and agency provided aerial photos. Consultant will inspect and inventory the <br /> interior of each traffic controller assembly and ITS telematics cabinets, identify and report deficiencies to <br /> the City operations staff, and make recommendations for equipment upgrades that would make <br /> significant impacts to signal and/or transit operations. <br /> Consultant shall investigate and document factors that are expected to affect signal and transit <br /> progression including, but not limited to: intersections with high pedestrian or bicyclist volumes; over- <br /> saturated intersections; uneven lane distribution; high volumes of trucks and buses; high-volume un- <br /> signalized intersections, including interchanges; parking maneuvers; presence and location of bus stops; <br /> differing signal timing patterns among local agencies; etc. <br /> Existing Conditions Survey Memorandum: Following the collection of all data and field surveys, the <br /> consultant shall prepare a memorandum summarizing the corridor's existing condition. The consultant <br /> shall also include an identification of all planned and programmed improvements (bike lane projects, <br /> intersection improvements, traffic signal improvements, transit improvements, etc.) on the project <br /> corridor. The identification of these projects shall at least include a list, summarizing all improvements. <br /> A photo document of each cabinet visited should be included in the Existing Conditions Survey <br /> Memorandum. The Existing Conditions Survey Memorandum shall also include a figure summarizing the <br /> existing corridor network's ITS and TSP elements. This figure should provide enough information as a <br /> standalone image to use for meetings and discussions with corridor agencies and other Project <br /> stakeholders. <br /> Subtask 2.2: Project Benefit Analysis <br /> This sub-task will build off the Existing Analysis and Assessment and generate existing metrics to <br /> measure Project effectiveness. The existing travel and safety conditions will be fully baselined and <br /> evaluated using high-resolution vehicle probe, high-resolution origin-destination (O-D), and stakeholder <br /> datasets. <br /> Performance Metric Data Collection: The consultant shall pull data from the traffic signal controllers, <br /> OCTA Swiftly platform (e.g. On-Time Performance, Speed Maps, Run Times), on-board bus videos, <br /> and/or consultant proposed high-resolution probe (vehicle speed and O-D) to measure the project <br /> corridor's baseline performance. The consultant shall coordinate with project stakeholders to identify key <br /> performance indicators that will baseline the existing travel and safety conditions along the project <br /> corridor and surrounding area, which may include, but is not limited to: <br /> • Average Travel Time, Delay, and Speeds <br /> • Bottlenecks in vehicular traffic <br /> 7 <br />
