Improving the measurement of mode share and mode shift

The proportion (share) of travellers using different modes of transport is known as ‘mode share’; ‘mode shift’ refers to changes in mode share over time. Traditional ways of measuring mode share (household travel surveys and censuses) do not produce sufficiently detailed, timely or comprehensive information that limits their use for planning and monitoring transport. Depending on the technology used, both approaches can also monitor travel activity more frequently (up to continuous monitoring), to observe mode-shift trends for different timescales.

This research reviewed conventional (household travel surveys) and emerging technology (screenline and link-based approaches). Several examples of advanced data infrastructure and capabilities are making significant progress towards continuous monitoring in NZ. However, this research discovered that no single technology or data source can effectively measure all transport modes, at all spatial scales and timescales. Data from conventional and emerging sources needs to be fused to comprehensively measure mode share and mode shift.

A toolkit was developed to harmonise approaches to measuring and reporting on mode share and mode shift. It contains guidelines on mode-share data requirements, and collecting, analysing and reporting on the data.

This TKH webinar will be hosted by Sandy Fong of NZTA and recorded.
