AI Technical Summary

Technical Problem

Existing tunnel lighting designs fail to consider the dynamic visual characteristics of drivers and the color characteristics of obstacles, resulting in a black-and-white hole effect, making it impossible to identify obstacles within the stopping sight distance and posing a traffic safety hazard.

Method used

Design a device for evaluating the rationality of highway tunnel lighting brightness settings, including a support frame, a conveyor belt, a tunnel model, a transparent cover, and an obstacle model. By simulating the light environment inside and outside the tunnel and vehicle movement, the rationality of tunnel lighting brightness is evaluated.

Benefits of technology

It enables dynamic visual simulation during the design phase, accurately assesses tunnel lighting brightness, avoids traffic accidents, and improves tunnel operation safety and economic benefits.

Abstract

The present application provides a kind of highway tunnel lighting brightness setting rationality evaluation device and method, belong to highway tunnel lighting test technical field.The device includes support frame, tunnel model made according to scale S, transparent cover covering model, three synchronous transmission belts and observation component.Adjustable lighting fixture is arranged in tunnel model, full-spectrum lamp strip is arranged in transparent cover to simulate natural light.Three transmission belts are used to move simulated road surface and tunnel model with barrier model, to simulate the relative motion of human eye and environment when driving.The method is simulated dynamically in stages, in a specific lighting scene, the instantaneous distance of the observer identifying the barrier is measured, and the actual visible distance is converted after comparing with the designed stopping sight distance, to quantitatively judge whether the lighting brightness of each area meets the requirement of safe driving.The present application solves the defect that static design method cannot evaluate dynamic visual process, and provides a scientific and intuitive verification method for tunnel lighting design.
