3rd Dimension, a New York-based company has introduced a new (free) application that allows drivers in New York, New Jersey and Connecticut to see live traffic videos on their compatible data-enabled cell phones. The service also works on BlackBerry, Palm Treo and Windows Mobile smart phones. Users can choose from more than 450 real-time traffic cameras along major crossings in the tri-state area, stretching from New Haven, Connecticut to Southern New Jersey and including New York City’s five boroughs. It was test launched back in November 2006. You can download it here.
