TED HUYNH, PE, TE Transportation Planning Task Support controllers and current operations at key signalized intersections, observed corridor performance, and evaluated queuing and operational issues. The project began March 2019 and completed in June 2019. Metro Orange Line (MOL) Environmental Clearance, Los Angeles County Metropolitan Transportation Authority (Metro) — Los Angeles, CA Mr. Huynh served as a Senior Engineer and reviewed the existing VISSIM model, including signal operations and vehicle behaviors, and helped to recalibrate the model, as well as prepare a calibration and results memorandum for the project. He then prepared the project VISSIM model, which included complex preemption parameters, revised geometrics, and updated signal timing. Iteris staff updated and expanded the traffic simulation model previously developed for the MOL Grade Separation Feasibility Study, which had served as the traffic analysis tool for comparing improvement alternatives along the MOL. The model network contains approximately 50 signalized intersections, including the busway priority and preemption signals and signalized intersections on parallel roadways. The project began in Nov. 2017 and is still ongoing. Mr. Huynh's involvement in project ended in March 2019. Redondo Beach Blvd Arterial Improvements — City of Gardena, CA Mr. Huynh served as Project Manager and Primary Engineer responsible for preparing a traffic study assessing the effects of median implementation on traffic operations along the corridor. Iteris provided transportation planning services to the City of Gardena regarding evaluating the operational improvements proposed for the Redondo Beach Boulevard corridor in the City. Improvements include improved signal operations, addition of extra travel lanes, and implementation of a raised median to replace the existing two-way left -turn lane (TWLTL). Iteris staff evaluated the traffic operations changes associated with implementation of improvements, including an iterative analysis of median locations and effects on left -turns along the corridor. The project began February 2019 and completed in June 2019. TIA Peer Reviews — City of Anaheim, CA Mr. Huynh served as Project Engineer responsible for conducting technical and peer document review for Disneyland traffic studies submitted to the City. Iteris provided transportation planning services to the City of Anaheim regarding reviews of traffic/transportation impact analyses/studies for iteris two proposed projects near Disneyland within the City. Iteris staff read and reviewed the documentation, including summaries and technical analysis, reviewed key inputs and data collection results, and documented findings in draft and final peer review memos. The project began in January 2019 and completed in May 2019. On -Call Transportation Support - Port of Long Beach, Long Beach, CA Mr. Huynh served as the Primary Engineer and Simulation Modeler responsible for corridor analysis along the Pico Avenue study area. The Port of Long Beach has asked Iteris to provide traffic engineering services involving a study of travel times, queuing, and intersection LOS performance for the Pico Avenue corridor while construction of the new Gerald Desmond bridge is ongoing. For the project the Port is removing and rebuilding multiple connectors and roadways, all of which alter traffic and circulation patterns in the area. This project began in March 2018 and completed in September 2018. US-1ol NB Auxiliary Lanes and NB/SB Ramp Metering PSR-PDS — City of Camarillo, CA Mr. Huynh is serving as the Project Manager and Primary Engineer responsible for public meeting materials, an initial work plan, an HCM and safety analysis, and overall preparation of a Caltrans Traffic Engineering Performance Assessment (TEPA) as part of an overall project study report/project development support (PSR-PDS). The City of Camarillo, in coordination with Caltrans, is proposing to construct new northbound auxiliary lanes along US 101 in order to enhance safety and improve traffic operations in the area. A supplemental assessment of ramp metering operational impacts was also conducted on behalf of the City, as an alternatives analysis study. This project began in December 2017 and completed in May 2020. Professional On -Call Traffic and Transportation Engineering Services — City of Diamond Bar, CA Mr. Huynh served as a Project Engineer responsible for conducting analysis review and peer document review for traffic studies submitted to the City. Iteris provided citywide traffic signal operations and on -call traffic engineering services. Services include, but not limited to, traffic signal operations and monitoring, traffic signal timing, TMC staffing, traffic signal installation and interconnect design, traffic management plan, and warrant analysis. This project began in Nov. 2017 and completed in Jan. 2020.
