Video captures vintage footage of NJ traffic monitoring, circa 1937

For those of you who love the rich history of New Jersey, here's a vintage newsreel you'll enjoy.

This 1937 footage shows New Jersey state troopers taking to the air to alert motorists of potential traffic jams. Yes, they had both motorists and traffic jams even in 1937.

At the time, it was a plan to help speed ease holiday travel. A communications officer takes off in a National Guard airplane to monitor the traffic and radio conditions to a police ground station, so drivers heading into heavy traffic can be directed, via their car radios, to head for less congested routes.

Less congested routes? What are those?
