The heavy traffic in Masana is a growing drain on the city' s economy--the clogging of the streets of the central business district alone cost the economy more than $1  2 billion over the past year
In order to address this problem, officials plan to introduce congestion pricing, by which drivers would pay to enter the city's most heavily trafficked areas during the busiest times of the day
Over 30 percent of the vehicles in the city's center are occupied by more than one person.
