This paper proposes two kinds of signal control strategies for a multiple-phase signalized intersection modeled as the switched server system. Firstly, a class of switched server systems is introduced, and then two kinds of scheduling policies of the server, i.e., priority-based scheduling policy (PBSP) and clear-oldest-buffer scheduling policy (COBSP), are considered, under which the switched server...
This paper proposes a macroscopic traffic flow model for urban traffic road network. First, dynamic digraph is used to model the urban traffic road network's topological structure. Then, traffic flow data which is based on an extended cell transmission model and the traffic shock wave theory are endowed to the dynamic digraph to construct a weighted dynamic digraph model. Finally, the modeling method...
In this paper, we present a modeling framework for complex networks, which is called Dynamic Graph Hybrid System (DGHS for short). First, we give a descriptive definition of DGHS. Furthermore, as a typical motivational example of DGHS, we apply it to model urban traffic signal control (UTSC) network, and the UTSC network model we propose is in fact a development of the well-known cell transmission...
