چکیده

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..

Analyzing Stop Time Phase Leading to Congestion Based on Drivers’ Behavior Patterns

Traffic oscillation, stop and go traffic, is created by different reasons such as: sudden speed drop of leader vehicle. Stop and go traffic commonly is observed in congested freeways results in traffic oscillation. Many theories had been presented to define congestion traffic based on laws of physics such as: thermodynamics and fluid. But, these theories could not explain the complexity of driv...

Advanced OR and AI Methods in Transportation AN INTERMODAL TRAFFIC CONTROL STRATEGY FOR PRIVATE VEHICLE AND PUBLIC TRANSPORT

This paper proposes a traffic-responsive urban traffic control strategy allowing a real time passive public transport priority. The proposed strategy is based on a store and forward modeling of both of the private vehicle and Public transport traffic. The regulator is designed using the linear quadratic, which allows a traffic responsive co-ordinated control for wide-area networks. The objectiv...
