Hi Mark,

You need to have access tags added to the bollard so that they can be
transferred to the way. Does your points file have lines like these in
it?
barrier=bollard {add access = no; add bicycle = yes; add foot = yes} [0x660f resolution 20]
barrier=cycle_barier {add access = no; add bicycle = yes; add foot = yes} [0x660f resolution 20]

I used the the default style file included. The last entries in points are:
barrier=bollard | barrier=bus_trap
    {add access = no; add bicycle = yes; add foot = yes} [0x660f resolution 21]
barrier=block | barrier=cycle_barier | barrier=stile | barrier=kissing_gate
    {add access = no; add foot = yes} [0x660f resolution 21]
