Milan's Area C cut centre traffic a third and paid for transit with the charge
Milan charged €5 to enter its historic centre: traffic fell 33% on day one, accidents nearly halved, and revenue funded more transit.
City of Milan · ATM (Milan transport company)
The solution
Milan's centre was congested and polluted; its earlier Ecopass fee had charged by emission class without enough impact. In January 2012 the city launched Area C, a flat congestion charge for driving into the historic centre.
On day one, traffic fell about 33% in the morning peak (against a 30% target): metro ridership rose 6%, buses and trams 10%, and ATM ran extra capacity. Residents received 40 free entries and a reduced €2 rate; non-residents paid €5.
After the first month the effect held — accidents fell about 44% — and the city reported traffic down even outside the zone, with no rebound at other hours. Revenue went into mobility and the system was administered through a simple web ticketing portal.
Why it worked
- A flat charge makes the external cost visible without complex emissions science
- Residents' free quota and discount defused the 'taxing your own voters' problem
- Extra transit capacity meant the mode shift had somewhere to go
- Monitoring and published numbers kept the debate about evidence
What can be applied
A road price works when the money visibly buys the substitute: charge the car, give residents a quota, and put the revenue into public transport so the charge is a service upgrade, not just a fine.
Aftermath
Area C stayed in place and became a permanent fixture, later extended to more vehicles and hours, with revenue funding cycling and transit investment. Its measured results made it a reference case for congestion pricing across Europe, years before other cities followed.
