Additional signal aspects will be needed to promote the speed-up project on wayside signalling,
where the braking performance needs an increased length of blocks. Three new aspects are
ergonomically investigated to ensure visibility for drivers and comfortable driving. Conclusions
are 1) A double green aspect before the proceed signal, which is a single green, needs three
lenses to make required separation of the two greens. 2) Repeating signal of the double green
should be one of two white-lights types, example A or D in figure 1 in this paper. 3) Adequate
flashing rate for the flashing yellow/green aspect after the single green may be 80 cycles/min
with a period of 50 per cent ON/50 per cent OFF.
