Intelligent roadwork planning with congestion forecasts

TRIAS Traffic Roadworks Impact Assessment

TRIAS - Traffic Roadworks Impact Assessment - is a tool that WPS developed together with PTV Group and LSGB (Landesbetrieb Straßen, Brücken und Gewässer) for traffic forecasting and impact analysis of construction measures.

Many cities in Germany and Europe are growing and densifying. At the same time, commuter traffic is increasing on the outskirts of conurbations. Construction measures at the expense of road capacity are becoming increasingly problematic, as capacities cannot scale linearly with the increase in traffic. Thus, the requirements for intelligent traffic planning are increasing. However, known software solutions for planning construction measures provide little or no information about the influence of the planned measures on traffic flow and road capacities during the construction period. This is where TRIAS comes in.

TRIAS simulates the effects of construction measures on the expected traffic situation and provides intuitively understandable decision-making aids for different planning variants. With the new software, traffic planners, coordinators and decision-makers can plan construction sites more intelligently and improve traffic flow.

The use of the TRIAS software has a long-term, positive side effect: the more intelligent planning effectively contributes to the reduction of CO2, nitrogen oxide and particulate matter emissions in cities.

Easy to use software

For the cooperation, WPS provides the intuitive frontend of the award-winning software ROADS (Roadwork Administration and Decision System) and PTV the powerful backend of the leading multi-modal traffic flow simulation software PTV Visum.

WPS had already developed the ROADS (Roadwork Administration and Decision System) application as a tool for coordinating construction measures in Hamburg as part of a research project. The software system, which consists of several workstation types, links a variety of tasks and processes with each other, thus simplifying construction site coordination for the authorities and developers involved. PTV Visum creates a digital replica of the traffic system in the Hanseatic city, using it to analyse current problems and identify opportunities for optimisation.

For the first time, users from the municipal and official environment receive an easy-to-understand and easy-to-use software solution that raises strategic construction site planning to an operational level. It can be operated even by non-experts without a background in traffic engineering. Thus, the traffic impact of planned construction measures can be analysed and alternatives evaluated.

TRIAS in action

TRIAS achieves major success in Hamburg

The LSGB, the highest construction authority in Hamburg, is already using TRIAS successfully. And the congestion forecast is also in live use at the traffic control centre.

Benefits for the LSBG:

MEDIUM- and LONG-TERM PLANNING (2-5 years)
Construction site coordinators can simulate the effects of construction measures with the associated interventions in traffic management, e.g. lane narrowing, lane closures or diversions.
The simulation tools can be used to run through different variants and construction site constellations and to examine their compatibility with traffic.
Even new colleagues who have not been working in the field for very long can make targeted decisions with the help of the tool.

Benefits for the VLZ traffic control centre:

SHORT-TERM and AD-HOC PLANNING
Police officers in the VLZ can simulate the traffic impact of disruptions in the traffic network caused by special and ad-hoc events and proactively initiate traffic-saving measures.
Using the simulation tools, recommendations for drivers to take evasive action can be passed on to the radio stations (TIC messages).
The VLZ gives drivers the possibility to avoid congestion situations depending on distance and to take into account daily obstacles such as road works, closures and traffic jams.

That's why TRIAS is the right software

Holger Breitling, member of the management team at WPS, sees the use of such a tool as imperative in view of urban densification and the simultaneous increase in inner-city traffic:

"Cities need support for smart construction planning: with the TRIAS simulation software, those responsible can immediately see how planning alternatives for construction measures will affect traffic flow - and this before the measures have been planned in detail."

Peter Möhl, Director Sales Traffic - DACH & East Europe PTV Group, agrees with Holger Breitling:

"Large cities are growing and densifying, the picture is similar for many medium-sized cities - planning software must be able to keep up. TRIAS combines the validity and performance of PTV Visum with an intuitive front end. This allows administrations to find the best solution for planning scenarios while keeping the learning curve for powerful simulation software flat."
