DESCRIPTION OF DATA ACQUISITION EFFORTS

As part of the overall strategy of refining and improving the existing transportation and air-quality modeling framework, the current project focuses extensively on acquiring disaggregate and reliable data for analysis. In this report, the authors discuss the data obtained thus far from various state and local agencies for use in the project. The data obtained may be classified into three broad categories: (1) zonal-level data, (2) link-level data, and (3) household-level data. These categories are discussed in the subsequent three sections. In each section, the authors describe the data sets, the agency from which the data were obtained, and the reason for obtaining the data.
