Global comparisons of mode choice and public transport assignment processes

This research and think piece compares mode choice and topic public transport assignment globally. A better detailed understanding of the differences may lead to improvements for all locations. As an example, in the US, the typical approach encompasses an elaborate mode choice model and a relatively simple public transport assignment. In Europe and Australia often the converse is true. Background, findings, conclusion: Many US transport models use nested logit mode choice, with multiple access submodes (walk, drive, park-and-ride, kiss-and-ride) and multiple public transport submodes (local bus, express bus, BRT, light rail, heavy rail, commuter rail). This produces a complex model with many possible choices. Given the relatively low level of public transport usage in most of the US, it is nearly impossible to estimate such a model from home interview survey data. Typically, many of the coefficient values are asserted and the bias coefficients adjusted to match observed subtotals. In some nests, the bias coefficients are fairly large, limiting the model’s sensitivity. However, this approach allows the model to match the observed trips closely by loading onto the public transport network separately by submode.
