摘要: This book is about 'Transportation-Markings' (here-after T-M). A T-M can be defined as 'any device which aids a mode of transportation (ship, plane, auto, train) by giving guidance, by expressing regulations, or by giving warnings.' That includes the whole field of T-M forms (also termed safety aids): lighthouses, taxiway lights, traffic signs, railway semaphore signals, radio beacons, buoys, traffic beacons, global positioning systems, fog signals, targets, obstruction beacons, day beacons, and hundreds of other T-M forms. There is no recognized discipline of T-M. It began as a notion of this writer and -- perhaps unfortunately -- it remains that.
