Public Versus Private Mobility for Low-Income Households

Empirical studies have shown that welfare recipients who own cars have a high probability of moving from welfare to work. A travel demand model adopted by the Sacramento, California, Area Council of Governments was used to examine the possible impacts of car ownership promotion versus transit improvements on job accessibility, work trips, and traveler benefits at the system level. In the car scenario, the zero-car households that were assigned a car had higher job accessibility and larger positive changes in traveler benefits than those in the base case scenario. The other households had lower traveler benefits, compared with the base case, because of slight increases in congestion. In the transit scenario, all households had gains in traveler benefits, and the households without a car gained more than those with a car. The households without a car gained more in traveler benefits in the transit scenario than in the car scenario. The total gain in traveler benefits was higher in the transit scenario. In both scenarios, the changes in total travel time, congestion, and vehicle miles traveled were small, but mode shares changed substantially. Show References
