Review of Road Impedance Function Modeling Research on Complex Heterogeneous Road Networks
To scientifically distribute the traffic flow of the road network and balance the road load,this paper reviews the research progress of road impedance function modeling in complex heterogeneous road networks from three aspects:the analysis of the influencing factors of impedance function,the modeling and application of impedance function under different infrastructure and new intelligent transportation technologies.It looks forward to the future research focus of road impedance function modeling from the aspects of multi-scenario modeling,low-carbon travel and multi-source data fusion.The results show that:1)The road impedance function model under a single infrastructure is rich in research,but there is a lack of in-depth analysis of the impedance function model of complex heterogeneous road network;2)Limited by application scenarios,the model has problems such as low portability,accuracy to be optimized,and difficulty in parameter calibration;3)The new intelligent transportation technology is more and more widely used in the modeling of road impedance functions,and the impedance function analysis in congestion queuing scenarios needs to be further studied.
