Book Synopsis Sign Luminance Requirements for Various Background Complexities by : Douglas J. Mace
Download or read book Sign Luminance Requirements for Various Background Complexities written by Douglas J. Mace and published by . This book was released on 1985 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal standards (FP-79) for luminance of retroreflective materials for traffic signs are acceptance standards; they provide no differentiation based on driver need. Driver needs for sign luminance are of 3 types -- luminance for sign comprehension, luminance levels that define sign legibility, and luminance levels for sign conspicuity. This study was directed toward establishing, for different levels of scene complexity, luminance levels for conspicuity of yellow diamond warning signs at night. A procedure based upon rating sign locations on 4 scales was useful for identifying low complexity and high complexity scenes.

Book Synopsis Minimum Highway Sign Luminance Requirements for Older Drivers by :
Download or read book Minimum Highway Sign Luminance Requirements for Older Drivers written by and published by . This book was released on 1996 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this research, the minimum amount of luminance required by older and younger drivers to identify a numerical legend on yellow warning signs at night was investigated. A field study was conducted for subjective and objective evaluation of seven yellow warning signs on a simulated two-way rural highway. The signs were prepared to have different retroreflectivity values thus providing different luminance values to the subjects.

Book Synopsis Sign Legibility for Modified Messages by : Frank D. Shepard
Download or read book Sign Legibility for Modified Messages written by Frank D. Shepard and published by . This book was released on 1987 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was conducted to investigate ways of increasing the legibility of signs with high background brightness. Research was limited to silver, yellow, and orange encapsulated lens sheeting materials, and modifications were made within the standards for highway signs as specified in the Manual on Uniform Traffic Control Devices. The results of the study show that in Virginia the legibility of selected signs with high background brightness can be increased by modifying the letter design.
