An Improved MFD based Regional Traffic Volume Dynamic Control
نویسندگان
چکیده
The connection between traffic congestion and regional demand has become a consensus. A reasonable road network inflow control is essential to prevent the occurrence of congestion. With a consideration of deployment of detectors, an improved macroscopic fundamental diagram-based traffic volume dynamic control method via the feedback control is proposed in this study. Based on OD distribution of trips and connectivity of nodes, a novel method is adopted to identify the key nodes, on which the detectors are laid. And Artificial Neural Network is adopted to predict traffic volume of those sections without detectors. As a case study, the proposed methodology is applied to the regional Road network which is located in downtown area of Nanning, China. Adequate survey and analysis are carried out under current road traffic conditions via simulation study. It is proved that the regional traffic volume dynamic control can ensure steady and orderly regional traffic flow, and enhance the mobility in a saturated traffic conditions.

Dynamic Traffic Assignment with Macroscopic Fun- damental Diagrams
Dynamic traffic management strategies (e.g. perimeter control, gating) that benefit from macroscopic fundamental diagram (MFD) dynamics provided promising results regarding their effects on network capacity and performance. However, this raises the question of route choice behavior in case of heterogeneous urban networks, where different parts are modeled with separate MFD functions. In this st...

متن کاملAn Optimal Dynamic Control Method for an Isolated Intersection Using Fuzzy Systems
Traffic flow systems are nonlinear and uncertain, so it is very difficult to find their optimal points. In traditional traffic control systems, the traffic lights of crossings change in a fixed time period that is not optimal. On the other hand, most proposed systems are sufficiently capable of coping with the uncertainties of traffic flow. To solve this problem, there is a need to develop expe...

Recent studies on empirical data demonstrated the existence of macroscopic fundamental diagram (MFD), which expresses an aggregated model of traffic dynamics linking accumulation and output flow of an urban region. Employing MFD in modeling of urban networks opens up possibilities to introduce a new generation of real-time traffic control structures and improve mobility. Although there are stud...
متن کاملPerimeter flow control of mixed bi-modal urban road networks
In this work we deal with the perimeter flow control problem of bi-modal urban networks by use of a three-dimensional Macroscopic Fundamental Diagram (3D-MFD). The 3D-MFD relates the accumulation of cars and buses and the outflow (or circulating flow) in a bi-modal traffic network. We assume that the impact of each mode on the traffic flow in the network is different, i.e. each bus can not be c...
