港口公路集疏運(yùn)貨運(yùn)交通量預(yù)測(cè)及交通配流研究
[Abstract]:In recent years, the rapid development of port logistics, port cargo throughput and port container throughput have formed five regional port groups around the Bohai Sea, the Yangtze River Delta, the southeast coast, the Pearl River Delta and the southwest coast. The national port cargo throughput is 8.32452 billion tons. With the rapid growth of port logistics cargo throughput, the functional division of labor and cooperation between port terminals, rear logistics nodes and their logistics parks have been formed. The concept and reality of port city is formed in the pattern of freight transportation such as wharf and logistics park, which makes the traffic volume brought by the collection and distribution of port cargo to the interior of the port and the traffic of the city where the port is increasingly prominent. This paper focuses on the prediction and distribution of port freight traffic flow. Firstly, the characteristics of port freight flow are analyzed. The composition of port freight traffic, the time distribution characteristics of port freight traffic flow, the function guidance characteristics of road network are analyzed in detail, and the Huanghua Port is taken as an example. The time inhomogeneity of port freight traffic flow and the function guidance of collecting and distributing network are analyzed concretely in view of the development trend of large port. Secondly, the paper studies the forecasting method of port highway transportation volume. This paper analyzes the factors that affect the traffic flow of port highway transportation, establishes the BP artificial neural network forecasting model of port freight traffic volume, and adopts the actual operation data of Huanghua Port highway transportation system, and adopts the Matlab simulation platform. The concrete verification analysis is carried out. Thirdly, the paper studies the distribution of port highway traffic, and improves the road resistance function according to the time distribution characteristics of the traffic flow and the function of the road network. The prediction data of Huanghua Port port transportation network and the TransCAD simulation platform are used to verify and analyze it.
