Språk: Engelska Språk: Franska Serie: ; topic V-92Utgivningsinformation: XIth international winter road congress 2002, Sapporo [Japan] / XIe congres international de la viabilite hivernale 2002, Sapporo [Japon]. Paper, 2002Beskrivning: 8 sÄmnen: Bibl.nr: VTI 2002.0071Location: Abstrakt: This study focused on how well road information display devices can fulfill their original functions in visibility conditions of falling or blowing snow in particular. Data were collected through a joint study conducted over a period of three years from 1996 at the Ishikari Blowing Snow Experimental Center of the Civil Engineering Research Institute of Hokkaido and other sites. We evaluated the display visibility of road information display devices based on light-emitting diodes (LEDs) and the emitted luminance and emitted colour from these LEDs, and have found a direction for the optimum display luminance and other contributing factors.| Aktuellt bibliotek | Status | |
