Implemented city-wide upgrade to Advanced Traffic Controller using MaxTime softwareDesigned rail preemption operation at traffic signals near light rail lineUpgraded and maintained Python-based interim traffic monitoring systemAutomated timing conversion from old signal timing database to ATC database by using GUI automationWrote several Python scripts to augment interim system by checking controller time clocks, archiving database files, archiving high-resolution logs, monitoring rail preemption activities, etc.Analyzed crash reports to determine safety could be improved by changing signal operationsReviewed traffic signal construction plans

Plano, Texas, United States

Optimized timing and operation of traffic signals using Synchro softwareMade changes to traffic signal timing when needed due to changes in traffic patternsAssisted with management of Traffic Incidents by making temporary changes to signal operations Managed the City's traffic control systemDeveloped and wrote specifications for city-wide upgrade to type-2070 traffic signal controllersDeveloped specifications for spread spectrum communications system to connect traffic signals with Traffic Management CenterInspected temporary traffic control zones for MUTCD compliance

Dallas, Texas, United States

As part of TxDOT-sponsored Traffic Light Synchronization (TLS) project, optimized traffic signal timing for several large signal systems (including Dallas CBD) using Passer-II and Transyt-7f, and verified results by performing floating car studies.Produced reports on TLS results which included stops, delay and fuel consumption, as well as economic benefit and benefit/cost ratio.Programmed NEMA TS-1 traffic signal controllers manufactured by Multisonics, Naztec, Econolite, Emco and 2M as well as type-170 controllers operating BiTrans 255 firmwareResponded to citizen requests regarding traffic signalsPerformed signal warrant studies
