Using anonymous traffic data from Android devices during the week of Thanksgiving last year, Google has ranked the 21 worst cities for Turkey Day traveling. 

According to the ranking, Los Angeles, Washington D.C., San Francisco, Philadelphia, and Dallas are the worst cities for traveling during the week of Thanksgiving. 

"According to Google’s data, you can avoid the heaviest traffic rush by not traveling on Wednesday afternoons. The majority of cities reported traffic at its worst between 3 p.m. and 5 p.m. the afternoon before Thanksgiving Day. Although, Honolulu, Providence, and San Francisco reported heaviest traffic on Saturday, presumably as people return home."

Worst 10 Cities for Travel: 
1. Los Angeles
2. Washington, D.C.
3. San Francisco
4. Philadelphia
5. Dallas
6. New York City
7. Chicago
8. Houston
