Research On The Optimal Allocation Method Of Spatiotemporal Resources Of Water Traffic Corridor

Shipping,as the main mode of transportation to communicate world trade since the Industrial Revolution,has matured through development,but as an inland waterway connecting inland and coastal areas is restricted by natural conditions,the inland waterway is increasingly congested.The construction of high-passage waterways helps alleviate waterway congestion.High-tonnage ships are favored by the shipping industry due to the traffic volume and the advantage of occupying clear waters.However,at the key control points of waterways,ship congestion at ship locks and channel congestion are becoming more and more serious.An important method to alleviate the congestion of key nodes of the waterway is the equilibrium distribution of ship travel time and space.Arnott extended the bottleneck model,proposed and analyzed the road corridor model,and studied the travel time and space distribution equilibrium problem.In this paper,we considered a water traffic corridor connecting industrial city clusters and foreign trade port cities.Inspired by the Arnott corridor model,the water traffic corridor model is studied,and the travel time and space equilibrium distribution is analyzed.Firstly,the definition of the unobstructed water traffic corridor and the unobstructed water traffic corridor for different forms of inland waterways,the establishment of the model of the unobstructed water traffic corridor,and the model and nature Mathematical proof is given,and a new method for calculating the congestion cost of the channel is given.Secondly,through the laboratory,online and on-site investigation of the Yibin-Yichang section of the upper Yangtze channel,the dynamic characteristics of the temporal and spatial distribution of ships traveling on the water traffic corridor are analyzed.An algorithm for solving the problem of unobstructed navigation corridor equilibrium is designed.Based on the survey data,the feasibility and effectiveness of the algorithm are verified,and the balanced travel distribution of the unobstructed navigation traffic corridor is obtained;the influencing factors were studied,and the channel navigability and standard ship types of the obstructed corridors were systematically analyzed.The model of obstructed water traffic corridors based on naturally formed channels was established.The model and travel cost function are theoretically proved,and based on the survey data,the algorithm that does not hinder the corridor balance problem is used to obtain Navigation obstruction for water transport corridor equilibrium distribution of travel.Finally,based on the traffic demand management strategy and equilibrium travel algorithm,an intelligent ship guidance system is proposed,and the Yangtze River is used as an example to analyze the current shipping traffic operation status and existing problems.Based on the traffic demand management,the ship intelligence guidance system and the new regulations of the Yangtze River channel management were proposed the equilibrium management strategy of traffic corridors,combined with the strategic deployment of the Yangtze River Economic Belt,was proposed,which was called a multi-modal integrated traffic corridor based on water traffic corridors.The research in this paper helps to reveal the formation mechanism and state evolution of ship congestion in inland waterways,deepen the understanding of the increasingly complex travel behavior of ships,provide channel balance information for voyage ships and channel managers,and thus provide water transportation decision-making and management Auxiliary support is of theoretical guiding value for improving inland navigation planning and management.
