Design And Implementation Of Road-rail Combined Transportation System For Urban Construction Materials Based On Path Planning Model

At present,China’s economy maintains a stable development trend of medium and high speed,commodity circulation is increasingly prosperous,and the transportation industry is developing rapidly while also facing the status quo of uneven development of the cargo transportation structure.The expansion of urban scale and the adjustment of urban layout have a strong stimulating effect on the demand for urban construction materials.In order to solve the problems of environmental pollution caused by material transportation and the continuous increase in transportation costs,comply with the national "the peak of carbon,carbon neutral" long-term development goals,various departments have increased the promotion of the "road-to-rail" transportation mode.The transportation of bulk goods represented by urban construction materials has been requested by many places across the country to use the "road-to-rail" transportation method as much as possible.Although the road-rail combined transportation network is constantly improving,how to integrate technology with actual business,intelligently and scientifically plan cargo transportation plans,realize the interconnection and intercommunication of information between enterprises,improve the overall business informatization level,improve the level of transportation process monitoring,and improve the intelligence of public rail transport system,all above which gradually become the focus of academic research..This thesis starts with the analysis of the transportation characteristics and business processes of urban construction materials and road-rail intermodal transportation.Firstly,the thesis puts forward the problems faced by the construction of the intelligent system of urban construction materials,and then analyzes the importance of path planning models to the construction of intelligent systems from the perspective of solving problems,then it constructs a road-rail intermodal transportation route planning model based on genetic algorithm with the goal of the lowest comprehensive transportation cost,combined with actual calculation examples,the feasibility and effectiveness of the proposed model are verified by comparing with the existing models in most studies.Secondly,guided by the intelligence of the system,this thesis further explores the practical application of the model.Based on the analysis of the intelligent problems in the road-rail intermodal transportation system,this thesis carries out the demand analysis and architecture design of the system,and fully integrates the path planning model of the highway and railway intermodal transport with the intelligent module of the system.In addition,this thesis also explores the application of new infrastructure in the road-rail intermodal transportation intelligent system.This article also explores the application of new infrastructure in the road-rail intermodal intelligent system,enriching the research content of road-rail intermodal route planning models and system intelligence.
