Abstract: As one of the most important, complex, and typical carriers in the evolution of human development, the road scene is a complex of road infrastructure and activity behavior, linking and constructing the "man-land relationship". Road scene perception has developed from two-dimensional abstraction to three-dimensional refinement, from static past tense to dynamic present tense. It has become the key technical support for smart cities, intelligent transportation, and autonomous driving, and is the core technical guarantee for China's new urbanization strategy and strong transportation strategy. Based on spatio-temporal traffic data, this paper proposes a new method for road crowd-sensing with high spatio-temporal resolution based on static infrastructure "form" and dynamic activity behavior "flow". From the perspective of static road network "form", the method takes "point-line-surface-body" elements as the research context, and constructs a theoretical system of high-precision road map crowd-sensing. In terms of activity behavior "flow", we break through the limitations of traditional point pattern analysis and develop a spatio-temporal modeling and multi-scale analysis method for spatial activity flow. In this paper, we reveal the evolution pattern of road scenes under the interaction of static infrastructure "form" structure and dynamic activity behavior "flow" pattern. Furthermore, we develop a road crowd-sensing theoretical system in which "form" controls "flow", "flow" determines "form", and "form" overlaps "flow", to provide core technology and data support for the development of smart cities and intelligent transportation.

Key words: road scene, big data, crowd-sensing, static infrastructure "form", dynamic activity behavior "flow", spatio-temporal modeling, interaction analysis
