Linking Transportation and Air Quality Planning: Implementation of the211 Transportation Conformity Regulations in 15 Nonattainment Areas. Executive 211 Summary

摘要

The Clean Air Act Amendments (CAAA) of 1990 require far-reaching efforts under211u001ethe 'transportation conformity' regulations to assure that transportation 211u001einvestments in non-attainment and maintenance areas are consistent with state 211u001ecommitments to meet national air pollution standards. This research documents how 211u001ethese regulations were implemented during the period 1991 through January 1998. 211u001eThe focal questions that organized the study are how has conformity affected key 211u001eagencies and constituencies' organizational capacity and relationships; how has 211u001econformity changed the transportation planning/programming process and its 211u001eresults; and how has conformity changed air quality planning and regulation. 211u001eAlthough the research does not attempt to evaluate the technical dimension of 211u001econformity modeling, it seeks to place the technical process in the larger 211u001econtext of the institutional relationships involved.
