RESEARCH EXPERIENCE

Traffic Operations and Safety Laboratory (TOPS)	University of Wisconsin - Madison, WI
Research Assistant	August 2008 - Present
FHWA Exploratory Advanced Research Program (EARP): Video Analytics for SHRP2 NDS Data (ongoing) Develop and implement computer vision pipelines for recognizing traffic signals and driving environment from low-resolution front-view videos of naturalistic driving WisDOT: Identification and Evaluation of Secondary Crashes on Wisconsin State Trunk Highways (2011 - 2014) Developed and implemented an algorithm for automatic identification of secondary crashes on a statewide freeway network. The algorithm is based on a linear referencing system and was found 30 times faster than a geographical counterpart Performed temporal and spatial analyses on accurately identified secondary crash data and provided practical information, such as secondary crash hotspots, for traffic incident management agencies WisDOT: Comprehensive Evaluation of Wisconsin Roundabouts (2008 - 2011) Developed tools to extract gap acceptance data from videos of roundabouts and calculate critical gaps and follow-up headways using the state-of-the-art methods Categorized critical gap (t_c) and follow-up headway (t_f) of congested roundabouts by roundabout geometry, vehicle type, and congestion level Established a driving path categorization system for multilane roundabouts, which accommodated the fastest driving path, and investigated the operating speeds under different path categories Used crash records, crash report forms, and field collected data to investigate vehicle conflicting patterns in roundabouts and applied Emperical Bayes (EB) method to evaluate safety improvements due to roundabout installation Wrote up Volume 1: Traffic Operations of the final report
Transportation Research Laboratory	Tsinghua University, Beijing, China
Undergraduate Helper	August 2006 - May 2008
Implemented a dynamic traffic assignment (DTA) module for an ITS project of Beijing urban traffic management, which was a core of the final delivery and later in the actual deployment Collected accurate traffic data over several most congested segments of urban arterials in Beijing Conducted surveys of travel behaviors among the diverse urban population of Beijing
Construction Laboratory	Tsinghua University, Beijing, China
Undergraduate Helper	May 2006 - May 2007
Investigated the safety storage of over-reinforced concrete beams Developed MATLAB programs to facilitate calculation of concrete safety performance

TEACHING EXPERIENCE

CEE 370: Introduction to Transportation Engineering	University of Wisconsin - Madison, WI
Teaching Assistant	Fall 2014
Led two discussion/lab sessions weekly for a total of 55 undergraduate students through out a 15-week semester setting Organized learning materials for students Prepared and graded the homework, the lab assignments, the exams, and the course project Office hours: 3 hours weekly, top rated by students for availability, responsiveness, helpfulness, and enthusiasm
