popgen3 3.0.4

A population synthesis and sample weighting tool for transportation planning.

PopGen3

Introduction

PopGen is a state-of-the-art open-source synthetic population generator for advanced travel demand modeling. Developed under the guidance of Professor Ram M. Pendyala at Arizona State University, PopGen utilizes a heuristic algorithm (IPU) to control and match both household-level and person-level attribute distributions.

Key Features

• Advanced control of household and person variables across multiple geographic resolutions (region and geo).
• Command-line interface for simplified usage and enhanced computational efficiency.
• Fully compatible with Python 3, with updated dependencies.

Data Inputs

Survey sample data:

household_sample.csv person_sample.csv

Population marginal data:

• geo-level marginals:
  person_marginals.csv
household_marginals.csv

• region-level marginals:
  region_person_marginals.csv
region_household_marginals.csv

Multi-Geographic Resolution Mapping Data:

region_geo_mapping.csv
geo_sample_mapping.csv

Example of Multi-Geographic Resolution Levels:

• Region Level: Set as census county subdivision
• Geo Level: Set as census tracts
• Sample Geo Level: Set as Public Use Microdata Areas (PUMAs)
