The Sacramento, California, region has been engaged in an innovative long-range visioning process in 2004 and 2005; the regional transportation planning agency is defining and modeling several 50-year growth scenarios. The authors worked with environmental and social equity citizens’ groups to define policies that would reduce emissions, serve lower-income travelers better, and preserve habitats and agricultural lands in the region. The citizens’ groups rejected the new freeways planned for the region as well as the substantial freeway widenings for high-occupancy vehicle lanes. In addition, they defined a more ambitious transit system, involving new bus rapid transit lines and shorter headways for all rail and bus service. This transit-only plan was modeled by itself and along with a land use policy for an urban growth boundary and a pricing policy for higher fuel taxes and parking charges for work trips. A new version of the MEPLAN model was used to simulate these scenarios over 50 years, and findings about total travel, mode shares, congestion, emissions, land use changes, and economic welfare of travelers are described.

Several transportation policy scenarios being discussed in the Sacramento, California, region were examined in detail by using an integrated set of transportation and land use models. The scenarios examined included a light-rail transit system, high-occupancy-vehicle lanes, and a highway beltway. These scenarios were compared with a baseline forecast that included built and committed transportation facilities out to the year 2020. The model systems used were the METROPILUS land use modeling system and the MINUTP transportation modeling package currently in use by the Sacramento Area Council of Governments. The model packages were linked in such a way as to allow an equilibrium adjustment process to be calculated within each of the 5-year time periods between the 1990 base year and the 2020 forecast horizon. The results of these analyses show small but significant differences in the outcomes of the several scenarios examined. Overall the results are consistent with expectations and illustrate the robust applicability of the method of approach, while at the same time raising some interesting questions as to exactly what issues might be encountered if any attempt were made to implement these scenarios in the region.
