互通式立交网络流的协同控制
Coordinated networks flow control for interchange
摘要
Abstract
On relieving the growing serious urban periphery traffic congestion, the problem of designing control strategy for interchange is considered, it is a novel research field with challenges. This paper presented a novel methodology based on graph theory and network flow theory, the former is used to modelling by unfolding a generic interchange into a directed weighted network with multi origins and destinations, and the latter is used to calculate the dynamic flow spectrum, clarify maximum flow and to certify the controlled ramp arc. In addition, two novel resistance balancing factors aim to increase the fairness of control are designed with ramp queuing lengths and redundancy time, incorporating flow spectrum and based on control theory, a linear model with a quadratic objective function is constructed, and the corresponsive control law algorithm is designed with the adaptive queuing management method. A preliminary simulation-based investigation of the virtual coordinated ramp metering control problem using the methodology demonstrates the comparative efficiency and its ability to maintenance network performance while balancing cost distribution is better.关键词
