| Summary: | 750-950 feet, 800-1000 feet, and 1200-1400 feet respectively. analyzed for their compliance with the MUTCD guidelines. application of LCS to freeway traffic management. attempt was made to correlate the difference in legibility to be understood by a majority of the drivers). For this, better understanding and utilization of LCS systems and will catches the attention of a driver in a limited time of characteristics that have a direct bearing on the legibility depth study of the interrelationships between the LCS designed to evaluate and compare the glance legibility determinant than the color of the display. Significant differences exist between the color versus symbol recognition displayed by the two signs was found to be in the ranges of displays were found to exist between the younger and the displays, color combinations etc), geometric features and distance of commercially available freeway Lane Control distances of the symbols displayed by the two signals were distances. The signal displays were visible but not legible. driver; however, significant differences in legibility of Effectiveness (MOE). It is the distance at which the sign evaluated was the sensitivity of glance legibility to the exposure. The glance legibility was evaluated and compared Fiberoptics, Inc. This study emphasized the visibility of the for the corresponding symbols displayed by the two signs. An freeway-lane-control-signing applications. The LCS used in gender and age of the subject. The glance legibility glance legibility distance was used as a Measure of Glance legibility of "Red X", "Yellow X", and "Green Arrow" hardware elements (e.g. the light intensities, symbol limitations so as to promote more uniformity in the of freeway LCS . In summary, there is a need to make an in- of the displays. Brightness of the sign is a greater older age groups. The results of this study will lead to a operation of LCS systems in the most cost effective manner pixel arrangement were found to be the main design possible; however, further research needs to be done as promote more uniformity in the design, installation, and recognized) rather than their comprehension (their ability to regards the factors contributing to the effective visibility Signals (LCS). Two prototype fiber-optic lane control signals were evaluated to determine their suitability for standard LCS displays (their ability to be detected and the differences in sign design characteristics. Also The glance legibility does not depend upon the gender of the The size of the sign, brightness of the display, and the the study were obtained from C.J. Hood, Inc., and Electro This thesis documents the results of a laboratory study traffic conditions, mounting characteristics, and driver |
