Abstract: The invention discloses a modeling and evolution method and concerning device of tunnel vision guidance systems based on optical attributes, which involves the sector of traffic information technology. The invention comprises obtaining the entity elements of tunnel visual guidance systems and the optical attribute information of each type of entity elements, according to the geometric parameters of the entity elements, establishing the BIM parametric geometric model of the entity elements, further combined with optical attribute information of entity elements, constructing the target BIM parametric geometry model library, as well as adjusting model parameters based on the target BIM parameterized geometric model library to realize the dynamic evolution of tunnel vision guidance systems.

Abstract: Disclosed herein are composites capable of self-repairing. In some examples, the composites include a binding medium and a plurality of binding medium-repairing particles. The binding medium-repairing particles disclosed herein comprise a reactive agent encapsulated in a shell, where the reactive agent can interact with the binding medium to form an aggregate in the presence of an aqueous medium. Also disclosed herein are methods for making the composites and methods for making the binding medium-repairing particles.
