H5 Database Structure

Polaris uses HDF5, rather than sqlite, when the volume of data to be stored is large. Currently the H5 file is organised into three top level folders:

1. link_moe - Measure of effectivness (MOE) data for each link - {volumes, speed, travel times, etc.}

2. turn_moe - Measure of effectivness (MOE) data for each turn - {penalty, flow rate, delay, etc}

3. paths - Paths (sequence of links) that were traversed by a sub-sample of the travelers being simulated

• Measure of Effectiveness (Link Volumes)
  • UID Conversion
  • Link MOE
  • Turn MOE
• Paths
