Generalized Camera Calibration Model for Trapezoidal Patterns on the Road
Abstract
We introduce a generalized camera calibration model that is able to determine the camera
parameters without requiring perfect rectangular road-lane markings, thus overcoming the
limitations of state-of-the-art calibration models.

Real-time Predictive Model for Turning Movements at Isolated Junctions
4.1.
Introduction
Estimating turning movements at intersections is an important component for traffic control,
management, and transportation planning. In particular, a real-time predictive model of turning
vehicles plays an essential role in designing signal plans at isolated intersections for adaptive
traffic control systems, because proactive signal control logic considerably depends on the
accuracy and resolution of real-time prediction of traffic flows.
