Advanced OR and AI methods in transportation

In the paper novelty vehicle trajectories random field (VTRF) traffic representation dedicated to networked hard real-time traffic control systems is presented and illustrated by PIACON control method. It is emphasized that existing multiple type high spatial resolution satellite and air based imagery together with conventional video, laser, GPS, probe-vehicles technologies are sufficient for VTRF estimation and prediction. Many advantages of VTRF proposal unattainable by conventional traffic models in the area of traffic control, surveillance and management problems are presented. The VTRF cases of spatiotemporal traffic random fields automatically selected by area traffic situation markers are illustrative for PIACON method..
