ELI5: Why is it that during the day, deer and similar animals in the same family avoid roads but at night they gather on the roadside by the dozens? Why don’t they just stay where they are during the day?

I searched and found a couple posts about why animals only cross the road when you are driving by, but all the answers were “they are always crossing, this is just the only time you see it.” However, this doesn’t explain the obvious difference in the number of animals that gather by the roadside at night as compared to the day even when the roads are just as populated.

They aren't on the move during the day generally. Deer for example are crepuscular. Meaning they typically (always exceptions) bed down during the day and middle of the night. They are up and moving at sun up and sun down.  Thus why you see them crossing the roads so much at those times.
