Dear Anzir,
Do you mean an all-point to all-point travel time map? Something
displaying the average travel time to all points? This sounds similar
to metric integration, which would of course be focussed on the centre
of the UK. I think you probably mean something more sophisticated
though, reflecting the configurational conditions of the road network.
Someone probably has done something similar but I haven't come across it
myself. Good luck!
Kind Regards,
Noah

I think the term "spatio-temporal map" is not relevant for what you
seek. In geovisualisation this term is generally used to show phenomenon
that vary over space and time. A typical example is an animation (of a
map) that shows the change of census boundaries over time.
Typically, the travel-time separations between places is shown as an
overlay over an ordinary map. For example, you can draw concentric
circles/irregular shapes outward from a point of origin, whereby the
radius of the shapes is an indication of time/distance from the origin.
You could also use some type of continuous shading instead of shapes to
show the variations.
