PTV Optima 19.5

New Features and Changes

PTV Optima Micro provides traffic forecasts for sub-networks which are typically a smaller selection of the large-scale Optima model.

For an high level introduction to Optima Micro, see:

→ How Optima works in a nutshell > OPTIMA MICRO

Optima Micro is an advanced module that can be deployed according with:

→ Installing Optima Micro

The modeling activity proceed through a set of operations based also on PTV Vissim and PTV Visum, as indicated in:

→ Modeling Optima Micro

About Optima Micro methodology and configuration, see:

→ Optima Micro

Optima Micro provides a new set of APIs, as indicated in:

→ Optima Micro

The Traffic Supervisor GUI provides:

• Two additional layers to manage Optima Micro sub-networks:

  → Micro Sub-networks layer

  → Micro Traffic Estimation layer

• A specialized area to manage Optima Micro simulation groups:

  → Scenario workspace

• Additionals KPIs

  → Adding a KPI > PTV OPTIMA MICRO: TRAVEL TIMES - Provider: Optima Micro

  → Adding a KPI > PTV OPTIMA MICRO: TOTAL VEHICLE TIMES - Provider: Optima Micro

New Features and Changes

A new API is exposed to get information about the Mid-Term Forecast scheduling.

New Features and Changes

GeoServer component has been upgraded to the version 2.15.5 (for more details, see GeoServer version).

Now you can deploy an Optima system architecture horizontally scaling the Geoserver component.

This option is capable to better handling the GeoServer workload, improving the performance of Traffic Supervisor (→ About Traffic Supervisor) and of the entire system.

The old installation setup is still applicable but the standard installation should follow the new paradigm.

→ Installing Optima: a scalable architecture

→ Installing Optima on three servers

New Features and Changes

A new version of API for triggering a Short-Term Forecast simulation.

This version is compatible with previous versions of Optima.

Now you can send a request to Optima to force the automatically starting of a new simulation, handling situations in which the engine is busy and you need to stop it.
