knitr::opts_chunk$set(echo = TRUE, include = TRUE, root.dir = here::here())

In this notebook, I go through my conceptual model and decide which variables from PSRC I will use to test each part of the model. I will create a list of variables from each dataset level (household, person, travel, etc). Finally, I will use this list to select the variables from each dataset.

library(tidyverse)
library(here)
# library(janitor)
prdat <- PSRCData::prdat

Intention {.tabset .tabset-fade .tabset-pills}

Attitude

Unfortunately, it does not look like we will be able to include "social factors" or "affect", as there are not any survey questions that cover these. However, We do have information about preferences.

Values and Beliefs

Preferences/Intentions

Surveys usually don't distinguish crisply between preference and intention.

For intention, we have the variables starting with wbt_. These are asking what would influence someone to use more transit and use their bicycles more. This definitely is the type of question that measures Intention to use these modes.

We also have the number of trips by different modes in past 30 days, names from mode_freq_1 - mode_freq_5. The modes include.

prefs <- prdat %>% select(starts_with("wbt_"), starts_with("mode_freq_")) %>% names()

HOWEVER: should mode_freq variables instead be used for Habit?

Social Factors

Role

There is the relationship variable, which could be used to define their role

prdat %>% select(relationship) %>% unique()

Or the life cycle stage variable `

Affect

Habit {.tabset .tabset-fade .tabset-pills}

Stand-in subsection

Potentially, the variables named from mode_freq_1 - mode_freq_5 could be used for measuring habit. These measure the number of trips by different modes in past 30 days. The modes include:

This set of variables is also included as potential option for measuring preferences.

There is also "usual way of commuting to current location/office" called commute_mode

Also the commute_ variables! These are showing habit.

Other modes (30 day) can be useful for ppl who don't drive to work.

Context/Facilitating Conditions {.tabset .tabset-fade .tabset-pills}

These have an indirect effect on travel behavior choices through their impact on intention and habit.
