It's clearly a segregated private residential road. There is parking spaces provided by the steps north east of Highgate for staff of Coffee #1 which wouldn't be accessible if vehicles were prohibited, and access to the homes on Elizabeth Parade wouldn't be possible if vehicles were prohibited. There are no signs to display any kind of restriction for vehicles, and the whole of Elizabeth parade is clearly split with different paving slabs to indicate a walking area/footpath. The entrance to Leaded Terrace and Percy Terrace signs also state "leading to Elizabeth Parade".

It's only usable for access, or from connecting from Percy Terrace to Longmead Terrace or the opposite.
