In an information exchange, the Prefectural government conducted a survey of commuters on their travel habits and at the same time gave them information on the car alternatives that are available (e.g., train schedules). JfS has the details, but the general gist is that around 25-35 percent more people took the train to work after the survey. Last year, the government increased the number of seminars on "the smart use of cars" and is looking for ways to implement new measures in the coming fiscal year. That's smart.
