workers still appear to have shorter commutes.<br />

Commute Patterns, <strong>by</strong> Length of U.S. Residency<br />

Because over a third of the Bay Area’s low-income residents are<br />

foreign-born, the travel behavior of immigrants may have important<br />

implications for transportation policies focusing on the low-income<br />

population. Table 5.4 shows how mode choice differs according to<br />

immigrant status and the length of time spent in United States. As<br />

length of residency increases for immigrants, the percentage who drive<br />

alone to work increases from 44 percent to 65 percent, the percentage<br />

who carpool to work decreases from 23 percent to 17 percent, and the<br />

percentage who use the bus decreases from 14 percent to 7 percent.<br />

Immigrants who arrived in United States before 1995 are still less likely<br />

than U.S. natives to drive alone and more likely to carpool or take the<br />

bus. Because of these trends, immigrants may have lower dollar<br />

expenditures on transportation and higher time costs than those born in<br />

the United States.<br />
