My commute environment is totally urban, some commercial, some residential but completely in the cities (Whittier, LaMirada, Norwalk, Los Angeles). 16 miles approx by bike every day; some minor variation depending on exactly which route(s) I take.

22 miles round trip each day via the Metro Green Line train ($3.00 per day train fare), no variation in train mileage at all!
