Incorporating Shared and Digital Mobility Services into Household Travel Surveys
This Recommended Practice addresses data collection techniques regarding shared and digital mobility services in the context of household travel surveys. It recognizes the diversity in contemporary mobility services and policies, and the rapid pace of change in both. It recognizes the challenge of adapting protocols to enable tracking of mobility service usage while maintaining the fidelity of the time series data that is a key requirement of many household travel surveys.
Rationale: This Recommended Practice addresses data collection techniques regarding shared and digital mobility services in the context of household travel surveys. It does not impose requirements on either the entities administering household travel surveys or operators of mobility services. Standardization of data collection techniques supports several important objectives:
• The prevailing ad-hoc approach to tracking shared and digital mobility services in household travel surveys mean that travel survey practitioners do not have reliable guidance to follow when considering whether to update survey protocols to track shared and digital mobility behavior. Standardization would establish baseline expectations and thus allow for efficiencies.
• Household travel surveys are routinely undertaken by many governments at national (e.g. USA, UK, DE, FR, JP) and subnational levels (e.g. every metropolitan region of the USA). Due to the policy questions raised by mobility services, there is a need for reliable evidence on which to base policymaking. These surveys provide a low- or no-cost opportunity to routinely track the impacts of mobility services via long-established and rigorous surveying protocols, and thereby address this need for evidence. Greater understanding of mobility-service activity and impacts will support increased long-term planning and investment.
• Collection, archiving and exchange of standardized data relevant to mobility-service activity will enable operators and public sector regulators in one geography to benchmark local circumstances and impacts of policy decisions against experiences elsewhere.
