From the viewpoint of macroscopic dynamic characteristics of single intersection traffic flow, a commonly used macroscopic dynamic deterministic traffic flow model for traffic control is developed. Furthermore, according to fuzzy control theory and the policeman's experience, multi-phase traffic light control strategy based on the length of the waiting(More)
This paper presents a new intelligent control strategy to solve the coordination control problem of urban arterial traffic. The whole control structure includes two layers - the coordination layer and the control layer. Public cycle time, splits, inbound offset and outbound offset are calculated in the coordination layer. Public cycle time is adjusted by(More)

A fire-new two-direction green wave intelligent control strategy was presented to solve the coordinated control problem of urban traffic trunk. The whole control structure was divided into the coordination layer and the control layer. The optimal public cycle time, up-run offset and down-run offset were calculated in the coordination layer, and the splits(More)
This paper discuses a proposed systems for acquiring the next intersection timing and generating the required speed at current intersection to cross next intersection without stopping at it. The system is speed module for next intersection prediction embedded in intelligent traffic light control system at intersection. It can also be designed for GPS based(More)
The realization of Intelligent Transportation System requires the traffic recording data of high quality and sufficient integrity. Such requirements call for pre-processing of the original data. Focusing on traffic flow and in according to the spatial and temporal correlation of traffic flow data, this paper proposes a data recovering method to recover the(More)
This paper investigates the global robust output synchronization problem for a class of nonlinear multi-agent systems. In the considered setup, the controlled agents are heterogeneous and with both dynamic and parametric uncertainties, the controllers are incapable of exchanging their internal states with the neighbors, and the communication network among(More)
An urban region traffic intelligent coordinated control method based on multi-agent is presented, and the control target is to make bus-weighted vehicle average delay least. A two-layer hierarchical control architecture is used. The high-layer is the zone intelligent controller (ZCA) deciding key intersection and adjusting common cycle length real-time. The(More)
