Problems solved by technology

[0004] This accessibility result based on the degree of spatial obstruction on the road network has continuously improved the authenticity of the result during the improvement process, but there are still two problems: (1) It is assumed that people choose the facility based on the principle of proximity, but in fact, People can freely choose service facilities, so there is a lack of consideration of the impact of uncertain visit behavior on accessibility results; (2) The measurement of spatial obstruction is still based on assumed theoretical values ​​rather than actual travel obstructions

Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0041] Such as figure 1 and 2 As shown, the present invention provides an accessibility assessment method based on trajectory data integration of human travel behavior, which is used to calculate location-based accessibility, including the following steps:

[0042] Step 101: Obtain the administrative area map, population data, target facilities f of the study area j (j=1,2,3...M, M is a positive integer greater than or equal to 1, and M is the total number of target facilities in the research area), the research area is carried out based on the administrative area map Spatial grid division, and each grid as a unit k i (i=1,2,3...N, N is a positive integer greater than or equal to 1, and N is the total number of units in the research area);

Abstract

A method for evaluate accessibility of the integration human travel behavior based on trajectory data. The method of the invention divides the user crowd of the target facility into the potential crowd based on the spatial obstruction and the actual crowd based on the trajectory data, respectively calculates the access probabilities of different crowd types to the target facility, and puts forwardthe integrated access probability of the two crowd types as the basis for judging whether a location belongs to the service scope of the target facility or not. The integrated service scope of the target facilities is generated by taking the integrated access probability as the constraint condition instead of the traditional spatial obstruction constraint, and the potential theoretical factors and actual travel factors are considered comprehensively. The integrated service scope is introduced into the two-step mobile search method to obtain the accessibility evaluation result. On the basis ofimproving the traditional accessibility measurement method, the invention proposes a method for approaching the real accessibility result by using the trajectory data from the point of view of the user use.

Description

technical field [0001] The invention relates to the technical field of accessibility assessment, in particular to an accessibility assessment method based on track data integration of human travel behavior. Background technique [0002] In the process of people enjoying common resources, fairness becomes an important issue. In the measurement of the fairness of the layout of public service facilities, accessibility is an important indicator (Gu Mingdong & Yin Haiwei, 2010; Jiang Haiyan, 2011; Niedzielski & Boschmann, 2014; Cheng Gang et al., 2016). At present, accessibility studies are mostly based on potential accessibility studies (Chen Jie et al., 2007; Song Zhengna et al., 2010; Wang, 2012; Páez et al., 2012; Niedzielski&Boschmann, 2014), which considers The connection form of is the key factor affecting the accessibility results (Song Zhengna et al., 2010). In particular, the connection form between the starting point and the ending point has become the focus of resea...
