Abstract

In this paper, we propose a camera-based probe car system for traffic condition estimation. The probe car, which mounts a stereo camera and a GPS sensor, measures the traffic density using a car distance map from the stereo camera and receives the velocity and position information of the car from the GPS sensor. A traffic control center creates a traffic condition map according to the probe car data and uses it for traffic control, car navigation, and bus/taxi scheduling. We implement the camera-based probe car system as an in-vehicle device using an image recognition processor and show its enough performance and speed for practical use.
