Anti-terrorism plan focuses on Via del Corso and Capitoline hill.
Rome is to introduce new security measures in key areas of the capital in the wake of the Barcelona terror attack on 17 August, when a van was driven into pedestrians, killing 13 and injuring 130.
Among the new measures Rome security chiefs have ordered the installation of large flower boxes, positioned to impede the flow of vehicles, on the stretch of Via del Corso between Piazza del Popolo and Largo Goldoni. Police will reinforce pedestrianisation and control the coming and going of trucks delivering merchandise to shops in the area.
There will no longer be direct access for taxis and chauffeur-driven NCC cars to the Capitoline hill, home to the offices of the city's mayor.
Other Italian cities including Milan, Florence, Turin and Bologna are introducing similar security measures following the Barcelona attack.
