Freight allocating method for track transportation system

Abstract

The invention provides a freight allocating method for a track transportation system; the method is a 'two stage and double proportion' allocating method which is provided based on a passenger travel multi-path choice probabilistic method. The allocating method comprises the following steps: describing road network information and presenting digitization; establishing impedance functions of the comprehensive travel; searching K pieces of gradual short paths by the OD relative distance and calculating the comprehensive travel impedance value of practicable paths; judging the path effectiveness and calculating the path passenger flow sharing proportion based on the comprehensive travel impedance; considering the correction of the transferring and the crowding degree on the path passenger flow sharing proportion; calculating the allocating proportion; and finishing the allocation of the freight. The freight allocating method can guarantee the total income from the track transportation system to be equally distributed according to the contribution of all operational entities and guarantees the interdependence relation of all elements in the system operation value chain thereof.

Description

【Technical field】 [0001] The invention relates to a method for sorting freight charges, in particular to a method for sorting freight charges applied in the field of rail transit systems. 【Background technique】 [0002] With the gradual formation of the overall network of urban rail transit in Beijing, the future rail transit network will show the complexity of road network structure and scale, the differentiation of line form, function and system, the diversification of investment and operation entities, and the variation of train operation modes. Due to the characteristics of diversification, high growth of passenger demand and the fluctuation of time and space distribution, operation management will also gradually transition to a new stage of network operation. Under the condition of networked operation, the network is interconnected and interoperable, and the choice of travel routes for passengers is more diverse. It is an inevitable trend of networked operation to adopt...

Problems solved by technology

The former is simple to classify the freight revenue according to the proportion of the line scale operated by each operator in the road network, which is simple and easy to implement, but there are obvious defects in accuracy and rationality; the latter includes the shortest path method and the multi-path selection probability method , the shortest route method only analyzes route selection based on time elements and ignores other subjective and objective factors that affect passenger travel route selection. The multi-route selection probability method takes into account the diversity of passenger travel routes, and can distribute freight revenue more scientifically, accurately, objectively and fairly , but this method does not consider the calculation of passenger flow distribution ratio and the correction of passenger flow distribution ratio
