Problems solved by technology

[0006] At present, some technologies that use mobile phone signaling data to analyze the traffic demand between traffic areas have appeared in the existing technology, but the actual situation is that not all residents have wireless communication equipment or some residents have equipment but have not Participate in surveys, i.e. not all travelers have devices that generate mobility data
Based on the traditional data collection method such

Embodiment 1

[0061] This embodiment provides a method for evaluating the current travel demand in a predetermined area, such as figure 1 shown, including the following steps:

[0062] S1: Obtain land use data, resident activity characteristic data, and wireless communication device data corresponding to the predetermined area within a predetermined time period. Taking the Shangdi-Qinghe area of ​​Beijing as an example, assuming that this area is the area we will study, the land use planning map of the research area can be in GIS format, showing the division of different types of land use areas in land use planning.

[0063] For the characteristic data of residents' activities, the travel situation of the residents in the predetermined area within a predetermined period of time may be visited and investigated, and the results of the investigation may be stored in a list or other forms.

[0064] The form of the data table and the results of model calibration are shown in Table 1.

[0065] ...

Embodiment 2

[0129] Different travel purposes roughly reflect the population, jobs and commercial attractiveness of each community. According to the characteristics of the community, the relevant norms in the field of transportation planning and the experience of professional and technical personnel, the growth rate of the population, jobs and commercial attractiveness after different prediction times can be estimated, and the traffic occurrence and attraction of each traffic community in the future can be obtained. quantity.

[0130] This embodiment proposes a method for predicting the future travel demand of the predetermined area, the method predicts the future travel demand of the predetermined area based on the data obtained by the method for evaluating the current travel demand of the predetermined area provided in Embodiment 1, The data includes the traffic generation attraction data of each sub-area and the actual travel demand OD matrix data between each sub-area within the predet...

Embodiment 3

[0170] This embodiment provides a system for evaluating the current travel demand in a predetermined area, such as image 3 shown, including:

[0171] A data acquisition unit, configured to acquire land use data, resident activity characteristic data, and wireless communication device data corresponding to the predetermined area within a predetermined time period;

[0172] A data analysis unit, configured to divide the predetermined area into n sub-areas according to certain rules, and obtain land use data and wireless communication device data corresponding to each sub-area within a predetermined time period through analysis;

[0173] A data fusion unit, configured to perform fusion processing on land use data and wireless communication device data corresponding to each sub-region within a predetermined time period to obtain first fusion data;

[0174] The information calculation unit acquires current travel demand information in the predetermined area according to the first...

Abstract

A method and a system for evaluating current travel demand and predicting travel demand in the future are provided. The method for evaluating the current travel demand comprises the steps: acquiring corresponding land use data, resident activity characteristic data and wireless communication equipment data in a predetermined time period in a predetermined region; dividing the predetermined region into n sub regions according to a certain rule and obtaining corresponding land use data and wireless communication equipment data in the predetermined region in each sub region by virtue of analysis; carrying out fusion processing on the corresponding land use data and wireless communication equipment data in the predetermined region in each sub region, respectively to obtain first fusion data; and acquiring the current travel demand information of the predetermined region according to the first fusion data and the resident activity characteristic data. By the aid of the method and system provided by the invention, the problems in the prior art that the evaluation result is inaccurate and is not in time and the data are inaccurate as a result of the condition that not all the travelers have equipment capable of generating mobile data are solved.

Description

technical field [0001] The invention relates to the technical field of traffic planning, in particular to a method and system for evaluating and forecasting traffic demand. Background technique [0002] Because the OD matrix quantitatively shows the spatial distribution of traffic demand in the network, it is of great significance for analyzing and solving urban traffic problems, so it has gradually been paid attention to in our country, and some cities regularly conduct traffic surveys to understand the characteristics of traffic demand. [0003] However, in the travel survey of residents, travelers are required to recall and record their previous trips. Respondents often cannot recall their travel information accurately, or lose patience because the survey items are too trivial, and refuse to fill in or fill in at will. Accuracy affects. [0004] With the rapid advancement of my country's urbanization process, the scale of cities is expanding day by day, and the construct...
