Benefits of Transit
You already know the benefits of taking public transit: Improved air quality, reduced traffic congestion, more time spent reading, surfing the internet, or relaxing rather than fighting traffic jams and other roadway hazards.
Now, research shows that the benefits of using transit hit even closer to home: your pocketbook. The American Public Transportation Association's monthly Transit Savings Report from September 2008 shows that a person can achieve an average annual savings of nearly $10,000 by taking transit. The figure comes from average national figures including gas prices, transit passes, and parking costs.
