Embodiment 1

[0031] The influence of the coordinated connection positions among various urban transportation modes is one of the important factors affecting the travel of residents. This is also a hotspot that urgently needs to be studied and deeply explored. The optimization of the system and the improvement of collaborative operation efficiency are particularly important.

[0032] The embodiment of the present invention provides a method for grading hot spots of urban traffic travel problems, such as figure 1 shown, including:

[0033] Step S10: Obtain the travel data of multiple measured objects. In the embodiment of the present invention, in order to more objectively and comprehensively obtain the problem hotspots, it is necessary to obtain as many measured objects and the travel data of the measured objects as possible. The travel data includes the position, moving state, and moving mode of the measured object at each moment from the starting position to the destination. In the emb...

Embodiment 2

[0107] An embodiment of the present invention provides a device for grading hot spots of urban traffic travel problems, such as Figure 8 shown, including:

[0108] The travel data acquiring module 10 is configured to acquire the travel data of a plurality of measured objects. For a detailed description, refer to the description of step S10 in the first embodiment above.

[0109] The problem hotspot determination module 20 is configured to obtain the problem hotspots according to the travel data of a plurality of measured objects. For a detailed description, see the description of step S20 in the first embodiment above.

[0110] The traceability hotspot determining module 30 is used to determine the traceability hotspot according to the problem hotspot and the travel data of multiple measured objects. The traceability hotspot is the starting point and / or the end point in the travel data where the transit time related to the problem hotspot is greater than the preset threshold ...

Embodiment 3

[0115] An embodiment of the present invention provides a computer device, such as Figure 9 As shown, the computer device mainly includes one or more processors 61 and memory 62, Figure 9 A processor 61 is taken as an example.

[0116] The computer device may also include: an input device 63 and an output device 64 .

[0117] Processor 61, memory 62, input device 63 and output device 64 can be connected by bus or other ways, Figure 9 Take connection via bus as an example.

[0118] The processor 61 may be a central processing unit (Central Processing Unit, CPU). Processor 61 can also be other general processors, digital signal processor (Digital Signal Processor, DSP), application specific integrated circuit (Application Specific Integrated Circuit, ASIC), field programmable gate array (Field-Programmable Gate Array, FPGA) or Other chips such as programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, or combinations of the abov...

Abstract

The invention provides an urban traffic travel problem hotspot grading method and device, and the method comprises the steps: obtaining travel data of a plurality of detected objects; determining problem hotspots according to the travel data of the plurality of tested objects; determining a traceability hotspot according to the problem hotspot and the travel data of the plurality of measured objects, wherein the traceability hotspot is a starting point position and / or an ending point position of the travel data, and the travel time of the starting point position and / or the ending point position is greater than a preset threshold; performing clustering analysis according to the problem hotspots and the traceability hotspots to obtain a plurality of hotspot regions; and grading the hotspot regions according to the total number of the problem hotspots and the traceability hotspots in each hotspot region. By implementing the method and the system, the problem hotspots and the traceabilityhotspots are graded, the problem hotspots and the traceability hotspots are weak spots for cooperative operation among urban transportation modes, and subsequent urban construction can be more targeted by grading the problem hotspots and the traceability hotspots.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for classifying hot spots of urban traffic travel problems. Background technique [0002] In order to meet the travel needs of urban residents, relevant departments have invested a lot of energy in road planning and construction to solve the problem of road congestion caused by heavy traffic flow, but the factors that affect the travel needs of urban residents and service levels are road congestion. , the synergistic connection between various urban transportation modes and the mutual influence of urban transportation subsystems are also one of the main influencing factors. It is particularly important to optimize and improve the efficiency of collaborative operation of various transportation subsystems. Contents of the invention [0003] Therefore, the technical problem to be solved by the present invention is to overcome the defects in ...
