Abstract

The invention relates to a baby carriage street pushing environment evaluation method based on a smartphone sensor, and particularly relates to a walking space quality quantitative evaluation method which is established by utilizing sensors such as a GPS (Global Positioning System) and an accelerometer of a smartphone to collect information such as speed, vibration and lifting in the pushing process of a baby carriage. The method comprises the following steps: firstly, determining indexes of baby carriage pushing in three aspects of quickness, smoothness and behavior complexity, performing index calculation by adopting GPS and accelerometer data of a smart phone, establishing a hierarchical structure model, determining a judgment matrix through questionnaire by utilizing an analytic hierarchy process, and performing calculating to obtain baby carriage indexes. The baby carriage index achieves objective evaluation of a slow-moving environment, especially a baby carriage pushing environment such as a sidewalk, from a quantitative perspective, and can provide a basis for urban street space improvement. Residents can plan travel routes according to the baby carriage travel indexes of all streets.

Description

technical field [0001] The invention relates to a method for quantitatively evaluating the quality of walking space, in particular to a method for evaluating the environment for stroller street promotion based on smart phone sensors. Background technique [0002] The sidewalk is an important part of the urban slow traffic system, which reflects the degree of civilization of urban traffic and the convenience of residents' life and travel. At present, the construction level of sidewalks in domestic cities is uneven, and there is a lack of corresponding evaluation standards. As a tool cart that provides convenience for babies' outdoor activities, baby carriages have a very high utilization rate, but so far the consideration of the comfort of baby carriages has not been generally included in the construction norms of urban walking spaces. The evaluation method can provide a reference for improving the quality of walking space. [0003] The walkability index is mainly based on ...
