Multi-frame sampling in household travel surveys: a Montreal case study

The latest household travel survey held in Montreal in 2018 included important methodological innovations with the sampling strategy. This paper first provides a portrait of the household survey samples and frames. It reports on the sample integration mechanisms adapted to the multi-frame approach and presents the strategies used to integrate data from various sampling frames. 13 different frames were used in this survey with some overlapping and time period issues. The article also presents the weighting method used for combining samples. The results show that the methods used made it possible to correct the main issues of the samples collected.
