This is a market research company that does surveys for the Federal Department of Transportation, HUD, and other federal agencies. They are a legitimate organization. You can confirm them by calling 1-800-842-4836. hey even will answer after hours if you select that option on the menu. Currently, they are doing a driving study for DOT.

I received two calls from 865-622-9039, the caller ID said Public Safety, but no one is on the line when I answered. I am on the Do Not Call list, but that seems pretty useless. Also getting repeat calls from M. Davis, 215-790-8900. The person on the line is pleasant and says she is calling on behalf of the Transportation Dept and asked how many teenage drivers I had in the family before I told her none of her business and hung up. The next night, 3-1-10 they called again and I chewed them out. They always call around 8:15 PM EST.

I am averaging 5 to 7 calls daily that start around 3PM and end around 8PM. Caller ID only shows the number. They hang up after the answering machine delivers it's message. If this IS the US Dept. of Transportation, they DO NOT want to talk to me, especially after they want a 40 cents per gallon gas tax, they are turning over our Interstates for mandatory tolling by 2010 and they want the Trans Texas Corridor and Nasco Corridor followed by three more of these quarter mile wide atrocities.

Received a couple of calls from this number, this time I picked up. Caller identified as being from U.S. Department of Transportation, doing a survey. I said I had previously completed a similar survey a few weeks ago. They asked for the youngest person in the household age 18 or older. Told them that person wasn't available; they said they would call back.
