  • Publication number: 20170337297
    Abstract: The present invention relates to a visual efficacy determining method for non-colored objects in different light environments, comprising: a) setting light environment; b) placing an object for performing visual recognition of a driver; c) resetting the light environment, and repeating the step b); d) processing visual recognition information data obtained after experiments, and establishing a correlating relationship between visual recognition time and color temperature, color rendering index and brightness parameters of the light environment; and e) performing visual efficiency analysis according to the visual recognition information data processing results. The present invention further provides a system for implementing the visual efficacy determining method for non-colored objects in different light environments, wherein the system comprises a simulated tunnel middle section subsystem, a testing subsystem and a data processing subsystem.

  • Publication number: 20170313237
    Abstract: This invention relates to an illumination standard calculation method for a tunnel middle section based on safe visual recognition: (a) Setting the light environment of the tunnel middle section; (b) Placing a target object in the tunnel middle section; (c) Making a driver drive a motor vehicle at different speeds toward the target object, and measuring the visual recognition distances D required by the driver to visually discover the target object at different speeds; (d) Resetting the average brightness L of the tunnel middle section and repeating the steps (b) and (c) to obtain a plurality of different sets of visual recognition distances D and corresponding brightness values L; (e) Using the S model to fit the data of the plurality of sets of visual recognition distances D and brightness values L to obtain the formula of the relational model of D and L to be L=0.683/(5.
