A Signalized Intersection Performance Code Using Vehicle Trajectory Data
This paper presents a uniform method for evaluating intersection traffic congestion from vehicle trajectory observations through a Signalized Intersection Performance Code (SIPC) - a time-space diagram segmented based on the dynamics of queue formation and dissipation in response to traffic signal control.

Inference of Signal Phase and Timing with Low Penetration Rate Vehicle Trajectories
We propose a suite of algorithm to estimate the signal phase and timing data for different types of controllers with low penetration rate vehicle trajectory data.

Traffic State Estimation and Uncertainty Quantification at Signalized Intersections with Low Penetration Rate Vehicle Trajectory Data
In this paper, we aim to answer one critical question - whether the available low penetration rate vehicle trajectory data is sufficient to estimate those unknown traffic states and parameters near signalized intersections.
