Urban multimodal transportation system simulation modeling considering carbon emissions

In the urban multimodal transport system, the rail-road container intermodal terminal plays an increasingly important role in alleviating urban traffic congestion and building a low-carbon transport system. In this paper, it considers the carbon emission factors and urban traffic congestion. Based on the dynamic analysis, it proposes a two-layer structure model based on discrete events. The meso-scopic model is the simulation model of traffic network flow and logistics service, and the micro model is the queuing simulation model of the interior of the container intermodal terminal. The 24-hour dynamic analysis of the actual port system shows that the model can analyze the dynamic characteristics, service targets and carbon emission indexes of network traffic flow and container logistics services from the tracking of the transport activities of individual vehicles, and evaluate the performance of railway intermodal terminals. The effect of the model will provide the basis for decision-making on the rational layout of urban multimodal transport network and the formulation of low-carbon transport policy.
