摘要: The Database demonstrates the unity and commonality of T-M but presents each one in its separate state. Yet in that process the full panopoly of T-M is unfolded including their shared and connected state. There are thousands of Trasportation-Markings. In addition, there are many variant forms, alternative names, untold permutations. The sheer number of forms may obscure the common thread of T-M that interweaves the multifoliated multiplicity. Yet ultimately the multiplicity leads to the basic unity of safety of whatever kind. The Database examines the four modes of rail, road, aero and marine T-M safety aids in separate studies through all remain components of Part I. This segment takes up Railway Signals. This aspect lacks an overarching term though Signals often includes non-signal forms. Signs, Marks, Markers has been added to Signals in the title.
