Problems solved by technology
Congestion charging (fare strategy) in the field of road traffic has become an important measure to alleviate congestion. However, the new fare system caused the initial passenger flow to decline, but soon the passenger flow returned to the existing level, and the growth trend is very strong; The reason why the fare strategy fails or the effect is not obvious is that the rigid commuter passenger flow accounts for a large proportion of the subway passenger flow, and its sensitivity to fare is low

Embodiment Construction
[0042] figure 1 The passenger flow distribution diagram of an example line is given, and it is assumed that the passenger flow between sections 3-4 exceeds the maximum transmission capacity of the line, which will form a capacity bottleneck. In practice, the performance of this capacity bottleneck is the retention of passengers on platform 3 of the station. In order to alleviate the bottleneck area, passenger flow control can be carried out on the front stations (1, 2, 3). Then, how to control the station 1, 2 or 3 is the key to solve the problem. Different control strategies can be adopted depending on the degree of passenger flow congestion. If the degree of passenger flow congestion is small, only station 3 can be controlled; Therefore, the basic idea of the method constructed by the present invention is: firstly, to identify the road network capacity bottleneck; secondly, to resolve the corresponding bottleneck, so as to reversely determine the corresponding control st...

The invention provides a road network passenger flow cooperative control optimization method based on a capacity bottleneck relieving strategy. This method first establishes the internal relationship between station passenger flow and section capacity occupancy based on passenger flow distribution without capacity constraints, obtains the passenger flow distribution status of the road network section, and then combines the section passenger flow transportation capacity to identify capacity bottlenecks, and based on the feedback control strategy to resolve capacity bottlenecks, and then countermeasures. To determine the control station, control time and control intensity. This method is suitable for the situation where the passenger flow pattern is obvious and relatively stable, and has good applicability to peak hours, and provides a theoretical basis for the normal flow restriction scheme preparation method during peak hours.
Description
technical field [0001] The invention relates to a road network passenger flow control method, in particular to an urban rail transit road network passenger flow collaborative control optimization method based on a capacity bottleneck solution strategy. Background technique [0002] The expansion of the scale of the subway network has led to the continuous growth of passenger flow demand, and the contradiction between passenger flow demand and transportation capacity has gradually become prominent. Especially in the morning and evening peak hours, the direction of passenger flow is obvious, and some sections have long-term high-load operation, and the phenomenon of passenger congestion and stagnation in stations and sections is prominent. , seriously affecting the operational safety of the urban rail transit network. In addition to the normal peak hours, large-scale events such as holidays, conventions and exhibitions, sports events and other large-scale activities lead to a ...
