问题
I want to trigger 'Public Transport' toggle button's action through code.

I have searched everywhere but I couldn't find any resource on this.

You can set the baseMapType
of the Display
using the standard setter as shown:
map.set("baseMapType", nokia.maps.map.Display.SMART_PT)
And then you can reset to normal by,
map.set("baseMapType", nokia.maps.map.Display.NORMAL)
