First off, the title should be Thailand UNESCAP / ASEAN Asian Highways, since UNESCAP does not recognize AH121 and AH123.
There are many missing points where a numbered national route intersects. I'm also giving the occasional rural road (RR) intersection where it seems to be a major road.
THA AH1:
KHM/THA
add Rt3446/RR2089

THA/MMR
A good deal of signage shows AH1/AH2 bypassing Nakhon Sawan on Rt122:
west end,
along Rt122, while a lot also has AH1/AH2 through town. Maybe make an alternate on Rt122? Rt122 is also the only route shown on the
2017 log.
So here's the intersections for taking AH1 along Rt122:
Rt122_S -> Rt1_NakE
Rt122_U*
KrokPhra (I can't find any signs putting Rt3005 this far north)
Rt3005
Rt122_U*
LR1-0021Rt122_U*
Rt122_N -> Rt1/122
Ditto for
Rt130, though it may just be at the east end.
