The aim of this Compendium is to organize an inventory of transportation data sources that can be utilized to supply the data identified through a strategic data needs assessment. For the purposes of clarity and efficiency of use, the report has been divided into four sections: Data Collection Methods; Secondary Data Sources; Internet Resources; and Technical Support Resources. The Data Collection Methods section has been divided into two primary sections which detail methods and technologies related to (1) sample surveys and (2) travel monitoring. These methodologies should assist state departments of transportation and metropolitan planning organizations in gathering both conventional planning data and new data dictated by multimodal planning and the 1990 Clean Air Act Amendments (CAAA) and the Intermodal Surface Transportation Efficiency Act (ISTEA). Discussions of implementation techniques (e.g., phone, mail, video, etc.), although not addressed directly, are interwoven into many of the descriptions of primary data collection methods. The Secondary Data Sources identified include those available from Federal agencies, state agencies, and private institutions currently involved in data collection and dissemination. The Internet Resources provide addresses and descriptions of multiple transportation related sites in the Internet, in addition to e-mail account addresses. The Technical Support Resources describe some organizations that could assist planners in filtering through and understanding large amounts of data and sources, as well as possibly recommend analytical techniques or software which can be used to manipulate transportation data. |
