Problems solved by technology

However, due to the differences in the characteristics of the two types of vehicles and the operational interference between them, there is a large difference between the characteristics of the mixed non-motorized traffic flow and the characteristics of the single-type non-motorized traffic flow
Existing studies have too ideal assumptions about the multi-stream traffic flow of non-motorized lanes, and cannot simulate the phenomenon of isotropic traffic flow well; characteristics, it cannot ideally reflect the heterogeneity of non-motorized traffic flow, and the lack of research on the cell transmission characteristics of heterogeneous non-motorized traffic flow leads to the inability to accurately calculate the mixed bicycle traffic wave

Embodiment 1

[0051] Embodiment 1: a kind of hybrid bicycle traffic wave calculation method based on space perception, such as figure 1 shown, including:

[0052] Step 1: Determine the traffic status of the mixed bicycle flow in the cell;

[0053] Step 2: Calculate the perceptual density of electric bicycles and traditional bicycles respectively under the corresponding mixed bicycle flow traffic state in the cell;

[0054] Step 3: Determine the total density and total flow of mixed bicycle flow in the cell;

[0055] Step 4: Calculate the traffic wave according to the cellular transport model.

[0056] Among them, determine which of the following traffic states the mixed bicycle flow in the cell belongs to:

[0057] (1) Free-flow traffic status. In this case, both types of bicycle streams are traveling freely with little mutual influence, and e-bikes can freely outperform conventional bicycles.

[0058] (2) Semi-congested traffic state. In this case, there is not enough space for the f...

Abstract

The invention relates to a hybrid bicycle traffic wave calculation method based on spatial awareness, and belongs to the technical field of transportation. According to the hybrid bicycle traffic wavecalculation method provided by the invention, by means of a hybrid traffic flow model based on spatial awareness, spatial ratios under different hybrid bicycle traffic states are analyzed, and hybridbicycle density and flow rate are determined, so that a hybrid bicycle traffic wave velocity is calculated through a cellular transmission model. By adoption of the hybrid bicycle traffic wave calculation method provided by the invention, the limitation that the assumption is too ideal when the operation of multi-strand bicycle flow is simulated by the previous methods, such that the isotropic traffic flow phenomenon cannot be better simulated, is overcome, and the hybrid bicycle traffic wave calculation precision is improved.

Description

technical field [0001] The invention relates to a hybrid bicycle traffic wave calculation method based on space perception, which belongs to the technical field of traffic. Background technique [0002] With the development of cities and the demand for transportation, the non-motor vehicle travel mode dominated by traditional bicycles in my country has evolved into a mixed non-motor vehicle travel mode in which traditional bicycles and electric bicycles coexist. However, due to the differences in the characteristics of the two types of vehicles and the operational interference between them, there is a large difference between the characteristics of the mixed non-motorized traffic flow and the characteristics of the single-type non-motorized traffic flow. Existing studies have too ideal assumptions about the multi-stream traffic flow of non-motorized lanes, and cannot simulate the phenomenon of isotropic traffic flow well; Based on the characteristics of non-motorized traffi...
