intended to provide visual guidance for passengers and rail transit vehicle operators to locate and operate primary exits during conditions of low light or darkness when the emergency lighting system has failed or when smoke conditions obscure overhead emergency lighting. This document principally addresses the design and use of passive-type markings due to their lower costs and maintenance requirements compared with an active marking design. However, if a rail transit system wishes to install an active marking system over a passive system, this standard does not preclude it from doing so.
