Don't wait and see—know what's coming. Traffic forecasting and impact assessment.
Traffic measures only take effect once implemented—yet the decision regarding them is made beforehand. With TRAFF-X, you can evaluate planned measures in advance: integrate your simulation model (e.g., PTV Optima, PTV Vissim, SUMO) into TRAFF-X and compare the results based on key metrics covering traffic (such as average speed or traffic volume), emissions (e.g., CO₂, particulate matter), and traffic safety. The results feed directly into strategic planning, remaining fully documented and traceable, complete with evaluations and comments.
In addition to scenario-based impact assessment, TRAFF-X also provides ongoing forecasts for stationary traffic: expected parking occupancy is calculated based on historical occupancy data, calendar and public holiday information, weather forecasts, and known events and roadworks—covering both the short term (the next 15, 30, or 60 minutes) and the long term (upcoming holiday periods). These forecast values are available via the dashboard and map and can be transmitted to mobility platforms and navigation services using standardized interfaces (DATEX II).
That's what you can achieve as part of the traffic impact assessment.
Prospect
Know what is coming before it happens.
Know the expected traffic and parking situation before it actually occurs—both in the short term (for the next 15, 30, or 60 minutes) and in the long term (for periods weeks or months in advance).
To achieve this, the short-term model analyzes trends from recent hours and projects them forward. The long-term model utilizes calendar-based data—such as days of the week, school breaks, public holidays, and bridge days—to provide forecasts for timeframes where no current measurement data yet exists.
Traceability
Underpin decisions.
With numerous display options in maps, diagrams and lists, you can visualize the suitability and meaningfulness of the measures taken and thus substantiate them based on facts.
Effectiveness
Demonstrate effects.
You have the opportunity to objectively present the effect that individual events or measures have had on traffic, be it positive, negative or neutral.
Assessment
Objectively substantiate decisions.
You evaluate the options under review based on the criteria relevant to your objectives and record your assessment—along with any comments—directly alongside the scenario.
This documents not only the result but also the process: which options were examined, why one was selected, and which key metrics were decisive. The insights gained feed directly into strategic planning.
Reliability
Continuously verify preview quality.
A prediction is only as good as its evidence. The models are therefore constantly retrained with new data, and the deviation between the forecast and the actual utilization is documented with statistical parameters.
Evaluations of weekdays and daily hours show where the forecast is reliable and where readjustment is necessary - for example after a change in parking space capacity. This way you know which statements you can trust in which situation.
Procession
Integrate information into other services such as navigation and information services.
Forecast data appears on your dashboard and as a map layer with color-coded occupancy levels, allowing you to see at a glance—for example—which facility is expected to be occupied in an hour.
Furthermore, you can transmit this data via standardized interfaces (DATEX II) to national mobility data platforms, navigation services, and apps. You determine, on a facility-by-facility basis, whether and in what form the data is published.
We show you how to shape the mobility of tomorrow using PRISMA solutions today—illustrated by concrete use cases involving TRAFF-X in the areas of assessment and forecasting.

In a metropolitan region, occupancy levels for the next 15, 30, and 60 minutes are forecast for more than a hundred parking facilities—including parking garages, Park & Ride, and Bike & Ride facilities. These figures are displayed on a dashboard and map and transmitted via DATEX II to the national mobility data platform and navigation services, allowing commuters to know before they even set off whether a parking space is still available. |

A major city's integrated traffic control center evaluates several strategic options—such as varying speed limits on a diversion route—before implementing traffic management measures. These options, along with a baseline scenario, are processed using a linked simulation model and compared based on traffic and emissions-related metrics. The option that best aligns with the city's objectives is then implemented. |

As part of a research project conducted by a federal agency, the impact of measures in a small town—which lacks its own comprehensive traffic model—is being estimated using an open-source simulation. This makes well-founded impact assessments available even in locations where decisions were previously based on empirical values. |

A railway infrastructure operator conducted a quality analysis of occupancy forecasts at a Park & Ride facility and statistically validated the results. Based on calendar, school holiday, and public holiday data, expected occupancy levels are estimated—even for the long term—serving as the basis for capacity planning and customer information. |
