Embodiment approach

[0086]According to an embodiment of the present invention, in the above A step, a mixed transport frame includes defining urban rail transit and designation standards;

[0087]Mixed transportation is a way in combination of the existing urban subway network and the last kilometer delivery service of the existing urban subway network and the last kilometer of delivery service based on non-peak hours; urban rail transit mixed transportation in non-peak hours is five stages. Specificfigure 2 Indicated. In the present embodiment, the first stage and the fifth stage is the vehicle delivery, the second stage, and the fourth stage are manual transport, transfer the goods from the vehicle to the subway car, and the third stage is the subway delivery.

[0088]In the present embodiment, the mixed transportation standard of the passenger flow is set, the passenger delivery is set, and the specific implementation is to be divided into passenger compartments and cargo compartments.image 3 As shown, di...

Embodiment 1

[0192]Based on the Ningbo subway network, the effectiveness and applicability of urban rail transit mixed transportation strategies were analyzed in non-peak hours.

[0193]Based on Ningbo subway network, such asFigure 6 As shown, according to the different distribution distances, the distribution range is S1, S2 and S3, respectively, such asFigure 7 Indicated. Urban rail transit mixed transportation strategy for urban rail transit based on non-peak hours is as follows:

[0194]

[0195]Table 2

[0196]The analysis results show that the distribution cost and service efficiency of mixed transportation and service efficiency are not as transported in a short distance delivery, but the mixing transportation is greatly reduced by the distribution cost of the vehicle and the vehicle transport distance of the vehicle transportation. Although the mixed transportation has two end freight stations within the medium distance delivery, the vehicle transportation has been delivered, but the mixed transport...

Abstract

The invention relates to the technical field of urban rail transit transportation organization, and provides an urban rail transit hybrid transportation method and system based on an off-peak period,electronic equipment and a storage medium, and the method comprises the steps: constructing a subway train hybrid transportation framework in the off-peak period; obtaining the maximum passenger flowvolume of a subway train in the off-peak period, and calculating the number of freight carriages of the off-peak subway train; taking the number of freight compartments as input data of a model, and determining a non-peak subway freight loading mode in a hybrid transportation framework; constructing an urban rail transit hybrid transportation model in the off-peak period; and solving the model based on an improved VNS algorithm, and outputting the freight cost, the freight carriage number and the freight loading mode of the urban rail transit hybrid transportation in the off-peak period. According to the method, extra freight income is increased under the condition that normal operation of urban rail transit is not affected, and macroscopic reference and theoretical basis can be provided for mixed transportation modes of different types of rail transit cities.

Description

Technical field[0001]The present invention relates to the technical field of urban rail transit, and more particularly to urban rail transit mixed transportation methods, systems, electronic devices, and storage media based on non-peak hours.Background technique[0002]With the continuous development of e-commerce and delivery, urban freight has become a key link for urban economy and social development. In recent years, the rapid development of the global logistics industry has led to the proportion of cargo transportation. Taking the express delivery industry as an example, according to the latest statistics, China's express delivery business ranked first in the world from 2015 to 2018, with an average growth rate of 35.33%. At this stage, highway transport is the main way of urban freight, and ground transportation tools such as pickup trucks and small trucks are usually used for freight. At the same time, the vehicle's freight brought about a series of issues related to urban traf...
