abstract="A framework is presented for considering the mobility benefits of improved transportation for the elderly and handicapped. Estimates of latent demand are presented, along with data from operational projects that suggest that actual demand for more travel by the elderly and handicapped may be very small compared to the latent demand figures. The small size of impacts makes quantification of the resulting mobility changes by means of average before-and-after trip rates impractical. A cross-sectional disaggregate modeling approach is suggested instead.<p />",
