City of Santa Ana | First Street Multimodal Boulevard Study RFP NO. 25-029 | Appendix A: Key Staff Resumes & Support Staff Qualifications City of Ontario, Traffic Operation Analysis, Ontario, CA Project Design Engineer. KT assisted city engineers with analyzing existing traffic conditions for many of the City of Ontario’s critical intersections and aided in the development of new solutions to improve the LOS of those intersections. He coordinated traffic data with representatives at the City of Ontario and performed manual traffic counts. He also developed and analyzed design alternatives for future conditions, cost estimate, and benefit/cost of various alternatives. City of Anaheim, Anaheim Regional Transportation Intermodal Center (ARTIC) to West Anaheim 4th District Bikeway Connector, Anaheim, CA Design Engineer. KT completed a field inquiry on existing field conditions to draft a base plan for design along several popular corridor attractions such as the Disneyland Resort Theme Park and the Honda Center in the City of Anaheim. He provided Class II Bike Lane design as part of the “gap-closure” widening of Brookhurst Street between Katella Avenue and Ball Road in accordance with CA MUCTD and City of Anaheim’s criteria. The objective of the project was to design Class II and III bike lanes to connect bicyclists from the ARTIC station to the numerous attractions in the City of Anaheim. Coachella Valley Association of Governments (CVAG), Regional Traffic Signal Synchronization, Coachella Valley, CA Project Design Engineer. KT was responsible for the project planning, field inventories upgrade, design, implementation, and operations of the Coachella Valley’s regional traffic signal system upgrades and signal synchronization improvements. CVAG embarked on the development of a valley-wide traffic signal interconnect master plan and signal synchronization of new and existing signals on the regional arterial roads. ITS is an integral part of regional efforts to maximize highway and arterial system capacity and improve operational efficiency. SBCTA, San Bernardino Valley Coordinated Traffic Signal System and Coordination Tiers 3 and 4, San Bernardino County, CA Project Design Engineer. KT was responsible for designing a wireless network to establish communications between traffic ITS devices and traffic management systems, improve feasible wireless communications technologies as well as review and analyze mapping data and aerial photography and topography to determine the best feasibility of the proposed wireless paths. KT helped coordinate with city staff in continuing the deployment of wireless communication network design for 371 intersections. The intersections belonged to multiple cities that form SBCTA and the wireless network design was tailored to meet the needs and requirements of the individual cities as well as SBCTA. City of Culver City, Traffic Engineering Services for Traffic Monitoring CCTV System Gap Closure, Culver City, CA Project Design Engineer. KT was responsible for upgrading 4 miles of fiber optic communication cable to integrate existing and new 32 CCTV cameras on an Ethernet/IP switch (gigabit fiber optic backbone). RCTC, SR 91/I-15 Freeway Toll Roads Expansion, Orange and Riverside Counties, CA Project Design Engineer. KT was responsible for designing and integrating a fiber optic communication network across Orange and Riverside Counties, spanning over 14 miles of interstate highway. He worked with a Cisco wide-area network capable of interfacing several different platforms utilizing dual gigabit backbones and redundant routing capabilities, including remote wireless and T-1 links. The project served three new Toll Zone Enforcement buildings along SR 91, six CMS sign locations, and 32 CCTV surveillance cameras throughout the project limits. Future build-out included integration of legacy OCTA control systems to transmit secure real- time enforcement video and traffic data to a centralized Command & Control Center in Anaheim, CA. OCTA, I-405 Express Lanes Design-Build, Orange County, CA Project Lead. KT was responsible for coordinating with the OC405 Partners Joint Venture for the constructability reviews focused on the electrical, ITS, and electronic toll and traffic management systems (ETTM) infrastructure design submittals prepared by the Pacific Infrastructure 405 Designers Joint Venture. KT prepared constructability reviews for the lighting concept plan, temporary TMS capacity analysis, temporary TMS performance monitoring plan, temporary RMS/CCTV/TMS details, and several design packages encompassing over 200 design plans. The project consists of converting the existing HOV lane to a tolled express lane and adding two new lanes (one tolled express lane and one general purpose lane) in each direction along I-405 between the 405/605/22 interchange through Orange County to the SR 73 toll road interchange. Value to City of Santa Ana KT’s hands-on experience with a variety of signal systems and software programs will be a valuable asset to the City. KT will thoroughly investigate the effectiveness of the current signal timing and evaluate the readiness of the system for advanced operations such as TSP, leading pedestrian phases and vehicle to infrastructure communications. He is well-prepared to collaborate closely with the City’s traffic signal operations team in identifying solutions that will keep traffic moving while reducing capacity on the corridor.
