ART 22/10 Establishing a methodology for integrated transport accessibility measures
Tender ID: 530860
Tender Details
Tender Description
To inform the establishment of a methodology for creating an integrated, multi-modal, multi-destination spatial accessibility measure, based on current infrastructure, demographics, and destination-based accessibility, to replace vehicle mobility-based measures.
The objectives of the research are to:
a. Review national and international literature and experience of accessibility measures in transport;
b. Identify typical accessibility datasets used in urban areas worldwide, which may not be readily available within New Zealand, and suggest other approaches to measurement which may be adopted in the short- and long-term;
c. Identify how active-mode network analytics could consider levels of service and desirability of links, given the data sets currently available in New Zealand;
d. Explain the various ways General Transit Feed Specification (GTFS) files have been used overseas (and in New Zealand) to inform aspects of spatial accessibility (with more of a focus on connectivity rather than PT performance analytics);
e. Identify weighting and calibration factors for saturation curves to quantify the diminishing additional benefit of reaching more destination types;
f. Use modal reach curves to quantify how far people are willing to travel in New Zealand to reach different destination types;
g. Develop appropriate weighting for integrating different destination types into measures that take the price of land and transport into account and represent the 'value' of reaching different destination types for different population groups; and
h. Inform production of a toolkit (being developed in parallel by Waka Kotahi – refer to “Additional information” below) that will enable assessment and measurement of accessibility based on a wide range of measures, in addition to access to employment, at all levels of the transport system.
