Projects
From 2018 to 2020, Predicting Lane Change Intensity within Urban Interchange Influence Areas , Objective was to propose and evaluate fast and efficient crossing options at innovative urban intersections for pedestrians and bicycles. Designed crossing options, optimized signal timing, developed and calibrated simulation models in VISSIM
From 2017 to 2019, Pedestrian and Bicycle Accommodations at Continuous Flow Intersections (2017–2019), funded by STRIDE at University of Florida (69A3551747104) , Objective was to propose and evaluate fast and efficient crossing options at innovative urban intersections for pedestrians and bicycles. Designed crossing options, optimized signal timing, developed and calibrated simulation models in VISSIM
From 2016 to 2017, Identification of Potentially Hazardous Roadway Network Locations Using Microscopic Observational Vehicle Data and Macroscopically Modeled Reaction Time , Target was to find correlation between accident rates on freeways and driver reaction time derived from a macroscopic traffic model so that safety hazard locations can be easily identified. Collected and analyzed accident data from the Triangle region of North Carolina, analyzed traffic data, developed statistical models
From 2015 to 2017, Developing a Systematic Approach to Improving Bottleneck Analysis in North Carolina , Objectives were to identify the most severe freeway bottlenecks in the Triangle region and in Charlotte, North Carolina and to develop a framework for the agency so that traffic congestion be mitigated efficiently. Analyzed traffic data, identified and ranked the most congested roads in North Carolina, developed statistical models
Speciality
Traffic simulation, Traffic analysis, Traffic signal optimization, Statistical modeling
