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.

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.
