"Accordingly, says Milan Mayor Beppe Sala, the city plans to maintain its metro system’s capacity at less than two-thirds of its pre-pandemic activity. Instead of the 1.4 million average trips it saw daily before the pandemic, it will accommodate a maximum daily ridership of 400,000."
Instead, they're focusing on supporting walking and cycling.
"As a result, Milan is going big on cycling and walking. Over the summer, the city core will be partly remodeled to give over 22 miles (35 kilometers) of road space previously used by cars to bikes and pedestrians. Those cars that are allowed into the center must adhere to a new reduced 30 kilometers per hour speed limit. The aim is to make traffic more fluid and give pedestrians more space to spread out safely."
