Traffic models and traffic frequencies

PTV Validate: Traffic model for the whole of Germany

Creating a local or regional traffic model is time-consuming and expensive. Nevertheless, a comprehensive and up-to-date traffic model is necessary for traffic studies, environmental analyses, but also for location analyses. And it is vital to assess the impact of infrastructure projects.

PTV Validate can be used immediately, therefore providing a time-efficient and cost-efficient alternative. Validate covers the entire German major road network, making it one of the largest traffic models on the market. The fully calibrated model has been continuously developed since 2005 with the help of the traffic planning software PTV Visum and delivers, among other things, car and truck traffic volume figures as a result. With Validate, you have access to all the information you expect from a traffic model – without the cost and time of creating a custom model.

The traffic volume figures, which are available including direction of traffic, can also be used for GIS analyses based on the street network from PTV Digital Data Streets for routes in categories 1 to 6.

In addition to the volume values for the average working day, PTV Validate also provides hourly data for all days of the week, which in turn are available tailored to Digital Data Streets for the entire German major road network.

Location analysis with PTV Validate

Due to the model approach of Validate, not only volume figures are available, but also the route of each modeled vehicle can be stored and evaluated with the PTV Visum software.

For location planners, such traffic flow data opens up new and innovative analysis possibilities: route-based traffic analyses provide insight into the source and destination of traffic flows surrounding the location and show the major routes used in each case. This allows areas that are underserved to be quickly identified for expansion planning, while also taking competitor locations into account.

Floating car data for real-time applications

Vehicles equipped with GPS devices record information about their position, route and driving speed throughout the entire street network. This data is called floating car data (FCD) and can be used to derive historical speed data or also for real-time applications. FCD based on GPS trajectories opens many possibilities for traffic modeling and analysis and provide valuable information for traffic planners and decision-makers. For example, they enable traffic planners to analyze capacity bottlenecks in the street network: hotspots where congestion regularly occurs can be identified and resolved.

Based on this, we have comprehensive real-time traffic data from HERE, INRIX and TomTom for optimum traffic control and congestion avoidance in our range. They can be used directly in PTV Visum and PTV Vissim.

Agent-based modeling

We offer further mobility models on the basis of agent-based modeling, which, among other things, provide information about the movements of the population within a precisely defined temporal and spatial section of a country.

The Senozon mobility model, for example, provides a detailed spatial and temporal image of a region and its infrastructure in high resolution and shows the mobility behavior of the population in public spaces on the basis of mobility surveys.

It is based on population and demographic data from the statistical offices, on the basis of which a synthetic, completely anonymous population has been developed. This synthetic population is statistically representative of the real population of the respective country.
