This is how PTV Flows works

PTV Flows allows traffic operators to effortlessly monitor and predict traffic in real-time. By leveraging machine learning, state-of-the-art algorithms, and automatic alerts, PTV Flows enables cities and road authorities to optimize their traffic management without the need for extensive resources or complex infrastructure.

Therefore, PTV Flows comes with a network map that is updated automatically and floating car data (FCD) from major data provider TomTom with extensive coverage. The software can be run from the browser or be integrated via API into existing systems.

To get the software up and running, traffic operators simply need to select the parts of the road network they want to monitor and set up alerts based on customizable KPIs. Now they can devote themselves to other tasks and wait for the first alert email to pop up, that might read like this: “In 30 minutes, the speed on Main Road will be under 20 km/h.”

Robust Self-Updating Traffic Forecasts

Short-term prediction of traffic flows is an important topic for any traffic management control room. The forecasted speed and the ability to focus on specific KPIs monitoring zones or corridors, help the system to identify patterns and trends that may not be immediately obvious to human analysts. The predictions allow the traffic operators to spot upcoming incidents up to 120 minutes into the future and to proactively manage traffic flow.

PTV Flows is self-learning and self-updating. The system stores the daily data in the historical dataset and each week automatically updates the clusters that are being used for forecast calculation.

Predictive Automatic Alerting

PTV Flows’s automatic and predictive alerts help traffic operators to stay ahead of potential problems and to act before congestion occurs. In addition to that, the alerts save valuable time and resources. By eliminating the need for manual monitoring of traffic, the system can minimize human intervention and allow traffic operators to focus on more urgent tasks.

The alerts are being sent as email and can be customized to the traffic operator’s preference. You can select which alerts you or other stakeholders (e.g. police officers) want to receive and when, and whether you want to be informed as soon as the problem has been solved.

Customization & Flexibility

PTV Flows can be adapted to your needs. The road network being monitored by the system can range from just a couple of streets to a whole region and is easily scalable in case your focus changes. The advantage: You only pay for what you need.

The KPIs on which the alerts are based on can also be customized (with different level of warning and alerts expressed in different colors) specific to a corridor or area and thus provide a more accurate picture of traffic conditions than just standard KPIs. They can be designed to reflect unique traffic challenges such as congestion hotspots, peak traffic patterns, or problematic intersections, and support informed and data-driven decision-making. In addition to that, the data from KPI charts can be exported as CSV for further analysis.

In case you don’t want a browser-based tool and prefer to integrate PTV Flows’ algorithms and results into your existing systems, there is also an API available.
