This invention discloses a method, medium, and device for analyzing the influencing factors of residents' green travel behavior. Based on the theory of planned behavior and interpersonal relations theory, the method constructs a comprehensive theoretical model of the influencing factors of urban residents' green travel behavior from a static perspective. Secondly, based on a survey of 817 residents in the Yangtze River Delta region, structural equation modeling is used to empirically test the driving mechanisms of different categories of green travel behaviors among urban residents. Furthermore, a social interaction perspective is introduced, and a simulation model is constructed based on scale-free networks and opinion propagation dynamics to simulate and analyze the group response characteristics and dynamic trends of residents participating in various green travel behavior decisions under different scenario parameters. Finally, targeted policy recommendations are proposed to more effectively promote urban residents' practice of green travel.

The device shown [Figure 1] transforms any type of waste bin (new or existing) by adding a magnetic anchoring system, thus preventing the bin from tipping over and consequently from scattering waste into the environment. This system allows bins to be anchored on public property. It guarantees that the bin remains upright, resisting inclement weather (wind and storms) as well as attempts to tip it over, for example, by animals. The system connects and disconnects solely through human action and manipulation. Once collection is complete, the bin is returned to its private location, leaving only the metal base plate in its casing on public property. This discreet and customizable base plate poses no risk to people with reduced mobility, pedestrians, or any other users of public spaces.This magnetic anchoring device for garbage bins, according to the invention, is intended to improve the comfort of city residents, garbage collectors, and sanitation and hygiene workers. It also represents an additional safeguard in environmental protection by preventing pollution from the dispersal of waste. (DRAWING)
