The purpose of this project is to study relationships between children's independent mobility and the use of active modes of transportation.
Contributors to this project include:

This repository contains the following subfolders:
Contains datasets for analysis. Organized into two subfolders:
-
all-purpose includes a study sample of trips by children for all trip purposes from the 2017 National Household travel survey. The same dataset is included as a *.dat file (for use in the Python/Biogeme models) and as a *.rds file (for use in R/mlogit models). There is also a readme file that describes the criteria for inclusion in the sample, describes what each of the variables represents, and shows some basic descriptive statistics.
-
only-school includes a study sample of trips to school by children from the 2017 National Household travel survey. The same dataset (usa-2017) is included as a *.dat file (for use in the Python/Biogeme models) and as a *.rds file (for use in R/mlogit models). There is also a readme file that describes the criteria for inclusion in the sample, describes what each of the variables represents, and shows some basic descriptive statistics. There is also a pair of files (*.dat and *.rds) with simulated data that vary each variable across a reasonable range while holding other variables constant. These are for generating figures with predicted probabilities to illustrate model results.
These are the scripts that generated the files in the data subfolder.
This includes one R script defining some functions that help set up data for analysis using the mlogit package.
This is a place to store files related to the literature review. So far, the only thing in here is working paper that we submitted to TRB in the summer of 2023.
Documentation to come.
