COOPERATIVE AGREEMENT NO. C -3 -2084 ATTACHMENT A KRAEMER BOULEVARD I GLASSELL STREET I GRAND AVENUE — TSSP CONSULTANT, if required to install or replace any traffic signal control equipment whether local intersection or central systems, shall perform due diligence in the determination of what types of systems are to be installed. NTCIP compatible systems with Center to Center (C2C) communications ready capability shall be installed. System Telemetry C2C or to intersections from Central or peer to peer shall be Internet Protocol (i.p,) based Ethernet over Copper, Ethernet over Fiber, or hybrid of those two, Serial Communications shall not be allowed. Closed Loop systems - - -. -.- ..shall not be continued,.supplled.nor installed without special consideration and.approval.by...00TA ...- . and APM. Sole Source systems or systems that are a linked subset or part of a sole source central system are not to be installed unless verification of need can be demonstrated to OCTA APM and CAMM Contract Administration per OCTA standards and policies. In the circumstance where a local Intersection system controller is a necessary sole source and there is no alternate substitute, the CONSULTANT shall procure the sole source local intersection controller unit. The controller assembly and appurtenances housing the local intersection system controller may be supplied by others. Deliverables — Task 3: 1. Report documenting: a. The field review (including photo logs) b. Recommended mitigations to perceived problems 2. Electronic versions of the report and all data files 3. Necessary Construction Documentation Task 4-. 'Before' Study CONSULTANT shall conduct a 'Before' field study report representative of the times and days for which synchronization plans will be developed. The report shall identify Measures of Effectiveness (MOE) to evaluate the effects of the synchronization plans. MOE's will likely include traffic flow, travel time, average speed, number of stops per mile, number of intersections traversed on green vs. stopped by red (Greens per Red) (note: Average Speed, Stops per Mlle, and Greens per Red are the new OCTA MOE, Corridor Synchronization Performance Index (CSPI)), fuel consumption reduction, pollution reduction, and other pertinent items. The CONSULTANT shall include the CSPI as part of the MOEs as they are easily identifiable by lay persons relevant to demonstrating corridor improvements. The Identified MOE's shall be compiled for the corridor using the floating car method and from either or PTV Vistro 2, §j hro 8.0 and from Tru- Traffic Version 10.0. At least five (5) runs will be completed in each direction for each of the three weekday timing plans (a.m., midday, and p.m.), and at least five (5) runs will be completed in each direction during the Saturday midday plan. Number of runs shall be consistent for both directions and time perlods. Based on engineering judgment and in conjunction with APM approval, CONSULTANT should subdivide the corridor into contiguous segments for the 'Before' and 'After' runs. CONSULTANT shall notify and receive approval from PARTIES on number of runs and contiguous segments to be accomplished. Project travel -time data will be collected using the floating car method, a laptop computer, a GPS receiver unit, and Tru - Traffic v 10.0, only. The report shall address likely optimization strategies for signal synchronization, specifically focusing on how to consider PROJECT optimization: end — to — end vs. coordinated zones, ideally, the analysis should include the floating car data and data collected as part of Task 2. However draft versions of the report can include previously collected traffic, travel time, or other data, if considered relevant and available. The evaluation report shall provide a very good understanding of traffic patterns on PROJECT throughout the weekdays and throughout the PVt'25
