'rush hour measure' is the definition.
'haste' can be an answer for 'rush' (thesaurus). I am not certain of the 'hour measure' bit.

'no parking round area' is the wordplay.
'no parking' becomes 'has' (I am not sure about this - if you are sure you should believe this answer much more).
'round' means to look at the middle letters.
'area' becomes 'extent' (I've seen this before).
The middle of 'extent' is 'te'.
'has'+'te'='HASTE'
