Is it appropriate to say 'Heavy Traffic'? I am referring to traffic as in roads and vehicles in this context.
Is using 'lot of traffic' more appropriate?
I think "Heavy Traffic" is quite commonly used and is totally appropriate
EDIT : On 2nd thoughts, i think they are both inter-changeble but it might depend on the formulation of the sentence - where one might suit better (depending on the overall style) as compared to the other.
