BE-TU: Built Environment and Transit Use Meta-database

The BE-TU meta-database provides a comprehensive repository of empirical built environment and transit use studies. Its purpose is to increase the visibility of relevant empirical built environment and transit use research, making future knowledge development in the field easier and more robust. A comprehensive identification, eligibility, extraction and coding framework was followed to construct the database (1).

Suggestions, feedback and use cases:

This meta-database is a living repository of research. Use this link to submit a study for inclusion in the meta-database, provide feedback or share an example of application of the database.


The datum of interest is the relationship between a transit use (dependent or outcome variable) and the built environment (independent or predictor variable). The database contains qualitative information about study design as well as high-level results, coded in terms of the direction and significance of each BE-TU relationship. The scope of coded data includes:

- Prior study citation information

- Descriptive estimates of relationships between BE and TU

- Dependent (TU) variables

- Independent (BE) variables

- Sample attributes

- Study design

- Model specification

Database Contents

1. BE-TU_Meta-database: Study design and descriptive BE-TU relationships from priors, coded at data-point level (3). Contains 1,662 data points from 146 priors identified from original search.

2. Priors_Reference_List: Citation information for priors. Contains 186 priors: 146 from original search (7 Dec 2017) and 40 from search update (30 Oct 2019) (4).

3. BE-TU_Metadata_study design: Index of column headers corresponding to attributes extracted from priors and corresponding levels.

4. BE-TU_Metadata_BE: Index of built environment variables and indicators coded in database.


Evidence obtained directly from the database should include reference to the database as well as the prior studies from which the findings or descriptive information is taken. Citation information for all priors is included in the database, and identifiable using numeric study design IDs.
