Abstract
This publication consists of 13 papers that examine regional modeling of nonmotorized travel; surveys of departure time choice; an integrated land use-transport model system; residential relocation choice; green and active access to rail transit stations; predictions of travel behavior before and after transportation system changes; and estimating mobile-source greenhouse gas emissions. This issue of the TRR also explores socioeconomic model systems for activity-based modeling; trip rates and accessibility; the outcome of transportation projects under uncertainty; costs and benefits of transportation alternatives; quantitative approaches for project prioritization; and estimating rest area use.
