Tirachini Hernández, Alejandro; Sun, Lijun; Erath, Alexander; Chakirov, Artem (Elsevier, 2016)The estimation of differences in the value of in-vehicle time sitting and standing is usually made with stated choice (SC) data, partly due to the lack of revealed preference data. In this paper, we use the observed behaviour ...
