Abstract: | This article investigates the carpool mode choice option in the context of overall commuting mode choice preferences. The
article uses a hybrid discrete choice modelling technique to jointly model the consideration of carpooling in the choice set
formation as well as commuting mode choice together with the response bias corrections through the accommodation of measurement
equations. A cross-nested error structure for the econometric formulation is used to capture correlations among various commuting
modes and carpool consideration in the choice set. Empirical models are estimated using a data set collected through a week-long
commuter survey in Edmonton, Alberta. The empirical model reveals many behavioural details of commuting mode choice and carpooling.
Interestingly, it reveals that interactions between various Travel Demand Management (TDM) tools with the carpooling option
can be different at different level of decision making (choice set formation level and final choice making level). |
