Method for optimizing operation performance of multiple transportation mode combinations based on transportation demand characteristics

Abstract

The invention discloses a method for optimizing operation performance of multiple transportation mode combinations based on transportation demand characteristics, which belongs to the technical field of configuration of operation performance optimization of multiple transportation mode combinations. The method comprises the following steps: providing a common regulation generated by transportation demand by analyzing and predicting comprehensive transportation demand and characteristics, constructing a generalized aggregate utility function according to the transportation demand characteristics, analyzing capability gaps of the comprehensive transportation demand through transportation distribution on a combined network of a multipath probability distribution method, constructing a proposal set for the multiple transportation mode combinations, determining comprehensive effects of each combination proposal in the aspects of transportation efficiency, transportation quality and transportation level, and finally providing optimization configuration of transportation capability combinations. The method can truly reflect objective and actual transportation demand, and integrally concern multiple transportation modes to carry out planning and designing on transportation resources, thereby preventing waste in resources and capitals caused by only considering single transportation mode, and effectively relieving bottleneck restriction of transportation capability on national economics.

Description

technical field [0001] The invention belongs to the technical field of configuration optimization of combined transport capacity of multiple transport modes, and in particular relates to a combined transport capacity optimization method of multiple transport modes based on transport demand characteristics for planning and design of transport capacity resources in an integrated transport system. Background technique [0002] Transportation demand refers to the spatial displacement needs of people and goods produced by national economic and social development in a certain region (country, economic zone, region) under certain social and economic conditions and in a certain period of time. It is not constrained by factors such as the existing comprehensive transportation market supply (technical factors), management system (administrative factors), nor is it constrained by transportation prices and payment capabilities. The demand for comprehensive transportation exists objectiv...

[0007] A combined transportation capacity optimization method for multiple transportation modes based on transportation demand characteristics, characterized in that the combined transportation capacity optimization method for multiple transportation modes is: using the input-output theory and the spatial price equilibrium method to predict and obtain inter-regional transportation The value and physical quantity of demand solve the problem that the actual demand cannot be reflected by using the transportation volume instead of the demand volume in the current practice; using the transportation engineering theory and the cost analysis method of transportation economics, from the cost of transportation suppliers, the cost of transportation demanders and the society From the perspective of transportation cost, the generalized comprehensive transportation utility function is constructed, and the multi-path probability distribution method is used to allocate traffic on the combined road network formed by the superposition of multiple transportation modes. The target rolling optimization method is used to obtain a scheme for the optimal configuration of combined transportation capacity of various transportation modes; specifically, the following steps are included:
