I don't presently have access to the data. When I did, the relationships were informally noted, though a general relationship seemed to hold.
Looking for "commute distance vs. income" I'm not finding much by way of useful results, though a commute time by state/city (tracked by the US Census) is available. That conflates private vehicle vs. transit use (transit tends to take longer), and congestion vs. distance. For the most part, the data show longer times in urban and coastal states, and much shorter especially in the intermountain / western plains states.
... Except for the deep south, where you'll find both low incomes and long commute times.
That's very broad-scale data, but provides a hint of disparity.
