Method and system for evaluating current travel demand and predicting travel demand in future

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...

AI Technical Summary

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 as the travel survey of residents and the method of using wireless communication device data to obtain residents' travel information in the prior art introduced above, it is impossible to accurately assess the current travel demand

Moreover, the existing technology does not provide a method and system for predicting the future travel demand of the traffic area based on the current travel demand obtained through relatively accurate assessment.
