The objective of the synthesis report is to identify available truck trip generation data and provide an assessment of the current state of the practice. The synthesis begins by identifying the needs for and uses of truck trip generation data. In each case, the critical issues and problems associated with meeting these needs are defined and discussed. The needs of transportation engineers, travel demand modelers, and state and regional transportation planners for truck trip generation data vary considerably. This synthesis report attempts to provide a balanced assessment of the state of the practice in truck trip generation data for alle different groups of practitioners. The data collected in the study are summarized and presented in appendixes for use by other practitioners. A summary of key issues that affect the collection and use of truck trip generation data is presented and the state of the practice is assessed with reference to these issues.
