System requirements

Optima Base includes the basic components for a PTV Optima implementation. This includes the PTV Optima preconfigured database (PostgreSQL), standard I/O web interfaces, measure validation, data fusion and administration components to handle access policies.

Optima Detection and Control (ODC) has the capability to detect incidents automatically and to raise alerts in order to inform the operator of the traffic management center about locations that require attention. Incident detection and alert generation are based on customizable triggers.

This module is necessary to enable the → Pollution dispersions API.

Hyperpath is a multimodal route planner. It provides the best path between an origin and a destination specified by the user, both for private transport and public transport.

Machine Learning Forecast (MLF) provides insights on the real-time traffic data evolution for the next 30-60 minutes, which are based on traffic measurements (speeds and traffic counts).

PTV Optima Micro provides traffic forecasts for the sub-networks which are typically a smaller selection of the large-scale Optima model, based on a large-scale city or a state.

Prerequisite Type	Details
Hardware	No additional prerequisites are necessary.
Software	Vissim The current version of Optima Micro requires PTV Vissim 2025 (see the Micro-XX.Y.ZZZZZ.zip\ptv-optima-micro\_RequiredVissimVersion.txt file). It's important to remember that: Vissim MUST BE installed on every Optima Micro Worker node of the cluster To handle Bosch emissions features, you need to install PTV Vissim 2025. Three Vissim modules must be available: Vissig Dynamic Assignment COM CodeMeter The CodeMeter User Runtime component must be installed on Optima Micro License Server. You can download the right version from:CodeMeter User Runtime. For Windows and Linux server Component name: CodeMeter User Runtime 8.20 (or superior) Data integration During installation activities, you need to integrate some specific datasets. Vissim Model It's necessary to get the Vissim_Model (see → Result of the process)  folder containing information about demand and supply for the micro-simulation subnetworks. Micro-simulation subnetworks, in PTV Vissim format, are copied with all complementary files to the respective machines, as listed: Folders representing the different day types. Subfolders representing the different micro-simulation subnetworks. Files (.inpx, .bew, .weg,. sig, .nodes) containing the micro-simulation models, demand, path choices and accompanying files (for example, signal controllers files). SQL statements for subnetworks and polygons It's necessary to get the SQL scripts that must be used to update the PTV Optima data model (see → Update Optima DB). Software components During installation activities, you need some third party software components. Before starting, download these components. Kafka & Zookeeper You can download Kafka & Zookeeper version 2.3.0 compressed packet from here. Microsoft .Net Framework 6 Download Microsoft ASP.NET Core Runtime 8.0. Licenses In addition to Optima license (see → License check policies), you need licenses for the Optima Micro License Servers. Before starting, make sure that you received license tickets for the activation.
Libraries	No additional prerequisites are necessary.

The Mid-Term Forecast (MTF) module is an online simulation engine which is based on a dynamic traffic assignment. It provides a forecast for: The next days (rest of the week)The next hours until midnight (rest of the day).

Optima Operational Planning (OOP) extends the common features provided by TRE (STF, MTF, and Scenario evaluation).OOP improves decision support for traffic management actions in order to minimize disruption or assess impacts and mitigation strategies as a result of planned future events such as maintenance, roadworks, sport events.

The pre-computed RLIN (Result LINks) module provides an XML file containing the latest forecast results. It makes the new data available into a file named computed-rlin-result.xml

Optima Public Transport (PuT) ETA provides advanced functions for public transport services.

The forecast can be done in parallel for multiple scenarios and allows for a quick comparison of the results based on customizable key performance indicators.

The Optima Short-Term Forecast module is an on-line simulation engine for traffic estimation and forecast, allowing for the calculation of a comprehensive model-based traffic state on all links of your network.

Optima’s Smart Display module provides decision support for the operator selecting the best messages for variable message signs (VMS). This is accomplished by calculating a ranking list of all events (e.g. incidents) for the VMS of interest.

The Traffic Supervisor module is the Graphical User Interface (GUI) of PTV Optima. It provides a rich, yet intuitive, web interface that allows operators of traffic management centers to:

• Monitor map-based traffic states, allowing them to manage and visualize all models and traffic data.

• Create, edit and manage events.

• Control and monitor different simulation tools.

• Compare scenarios and manage alerts.

TRE Offline is the module that enables Visum modelers to carry out offline modeling activity necessary to provide Optima with the required input for simulation-based engines. The offline activity consists in the construction and calibration of the base model (see → How Optima works in a nutshell for more details).

Optima’s Vehicle Tracker module allows for the use of FCD (Floating Car Data) that may be originating from, for example, dedicated probe vehicles or public transport fleets. This provides a valuable data source regarding current speeds and disturbances on network links.
