Resumen |
Light levels were measured in the driver's (motorman's) cab of trains of the Moscow (USSR) metro and in the tunnels and stations. The visual acuity of drivers, corrected for preadaptation and stray-light conditions, was tested in the laboratory. The results support the following recommendations: to reduce the demands of periodic readaptation, headlights should illuminate the walls of the tunnel as well as the roadbed; the walls should be light-coloured (reflectance ≃ 0.3); the brightness of the surfaces in the driver's field of view should not exceed 1500cd/m2; station lights should have diffusers, and the upper third of the cab windows should be covered with a neutral light filter; the 100m of tunnel before a station or yard should be painted a light colour and illuminated to a brightness of 1000-1500cd/m2. |
