| 摘要： | Transportation-Markings (T-M) is a study of safety aids from an inter-modal perspective. The study has resulted in a series of monographs: Transportation-Markings: A Study in Communication Monograph Series. Transportation-Markings can be defined as any device (external to a transportation mode) which aids a specific transportation mode (road, rail, aero, marine) by giving guidance, by expressing regulations, or by providing warnings. Transportation-Markings can be visual, acoustical or electronic in their message-emitting character. Visual aids can be fully lighted, partially-lighted, unlighted or indirectly lighted. Acoustical forms include bells, whistles, sirens, tweeters. |
