The Public Life Data Protocol (PLDP) describes a set of metrics that are important to the understanding of public life—people moving and staying in public space—and aims to establish a common format for the collection and storage of such data. Used in conjunction with the Public Life Data Tools or other observational methods for collecting data about people in public space, the Protocol provides the structure for the data you collect.

Gehl Institute and its partners—Gehl, the practice, the Municipality of Copenhagen, the City of San Francisco, and with support and input from Seattle DOT—have together developed and launched the Public Life Data Protocol.

The PLDP provides a standard way of documenting the data collected through public life surveys. Therefore, the first step is to conduct a survey.
Public Life Surveys can be used to measure social and physical elements of public life. We've created tools to help you measure elements such as: people moving, social space, and building facade activation. You'll find templates for 9 different surveys in Survey Templates.
Guides (in English and Spanish) for conducting a survey can be found in Survey Guides.
Sidewalk Labs built a prototype Andrioid and iOS app, which is open source, to make public life data collection easier. See the CommonSpace GitHub repository for more information.
The PLDP provides guidance for compiling your data in a standard format so that it can be compared with other datasets. You can find spreadsheet templates and detailed instructions in Public Life Data Protocol.
We're compiling a list of datasets from the PLDP. You can study and learn from others or contribute your results: pldp_datasets.md
We welcome contributions to the project, please see the CONTRIBUTING.md for more details.
