This digest is intended to provide transportation planning practitioners with early information and initial research results of an investigation into standardizing elements of household travel surveys. While the research project continues, this digest provides an initial glimpse into areas where these surveys can be effectively improved through standardization. It should be of particular interest to professionals in transportation planning, survey design, data collection and management, and transportation modeling. This digest describes the findings from Phase 1 of National Cooperative Highway Research Program (NCHRP) Project 8-37, in which current travel survey practice is reviewed and procedures for standardization are identified and prioritized. |
