What's New

Version 4.2.2 (August 2019)

Updated the following libraries:

  • New "Timing and Actuation" metric that provides a detailed view of the vehicle and pedestrian cycles for each phase overlaid with vehicle and pedestrian actuations.
  • Changed the "Pedestrian Delay" metric and replaced event code 45 with event code 90 and some logic so it works for all controller vendors.
  • Integrated Intelight's pull request that adds an async version of GetMAXTIME records that is more tolerant of slower network and DB servers.
  • Added support for Econolite EOS Controllers.
  • Repaired Aggregate Data
  • Fixed several bugs

What's Next

Version 4.2.3 (Winter 2019/2020)

  • GDOT to enhance the source code to add an installer program.

  • Add a WEB API
  • Fix minor bugs

Version 4.2.4 (Anticipated Winter 2019/2020)

  • Higher level dashboards of performance measures using aggregated data.
