Destination choice model

[Daros Kpikpidi]

Hello Prof

I would like to have some of your advice on using biogeme for a model. Indeed,

I want to use Biogeme to extimate a model of choice of destination, that is to say a specification of the form Vij = Beta_duree * Duree_ij + Beta_distance * Disatance_ij + log {population_j + Beta_emploi * Emploi_j}.

with i the origin and j the destination

I have 40 TAZ (Traffic analysis zone) and in the literature it says to make a random choice of a small number of alternatives for each observation. Let's oppose that for each observation I want to consider 20 alternatives, how to do it with Biogeme?

In addition, with biogeme, it will be necessary to have one column per variable (in the model) according to each alternative. I do not have in my base. since if I take a trip from an origin 1 to a destination 6, we can only have the duration, the distance for this only alternative. I don't have the duration and the distance of 1 to the other 39 alternatives. How to proceed please?

It is just a data preparation issue. You need to prepare your data file using Pandas, Excel, or whatever database software that you like.

In addition, with biogeme, it will be necessary to have one column per variable (in the model) according to each alternative. I do not have in my base. since if I take a trip from an origin 1 to a destination 6, we can only have the duration, the distance for this only alternative.

Well, like for any revealed preference data, you’ll have to impute the variables for the unchosen alternatives.
