Developing a Successful Stated Preference Methodology for Determining Destination Choice Coefficients and Using it to Investigate its Empirical Structural Relationship with Toll Route Choice

Applying stated preference to destination choice has been little researched, partly because of the need for many more alternatives than could be available with stated preference. However during the course of several successive stated and revealed preference surveys, we have developed a successful experimental design and survey instrument so as to measure destination choice coefficients. We have taken this further so as to deal with the combined choice of destination and toll route. We have used this stated preference and revealed preference experimental design to investigate whether destination choice is above toll route choice or vice versa. This paper traces the different approaches adopted in a series of stated and revealed preference exercises in Nigeria in an attempt to understand this structural relationship between destination and toll route choice and reports on the final successful approach. It presents the detailed estimation results from the successful survey together with the estimated structural parameters using simultaneously estimated nested logit model estimation.
