Abstract: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, alternate 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 unit of safety of whatever kind. The variety and diversity points to a restricted system of messages serving one essential purpose: the promotion of safety. The perennial conundrum of the one and the many is found here in T-M. But the one and the many also intereact and explain one another.
