Intelligent roadwork planning with traffic flow forecasts
The solution to optimise traffic flow
TRIAS – Traffic Roadworks Impact Assessment – is a tool that WPS developed together with PTV Group and LSGB (Landesbetrieb Straßen, Brücken und Gewässer) for traffic flow forecasting and impact analysis of construction measures.
Many cities in Germany and Europe are growing and densifying. At the same time, the shuttle traffic is increasing on the edge of metropolitan areas. Construction measures that temporarily reduce road capacity are becoming increasingly problematic as capacities are failing to scale linearly with the projected increase in traffic. Thus, the demand for intelligent traffic planning is growing. Well known software solutions that support the planning of construction measures, however, provide little or no information about their impact on traffic flow and route capacities during the construction period. This is where TRIAS comes in.
Software for better decisions
TRIAS simulates the effects of construction measures on the expected traffic situation and provides intuitively understandable decision-making aids for different planning variants. With this new software, traffic planners, coordinators and decision-makers can plan construction sites more intelligently and improve traffic flow.
Driving cleaner through the city
The use of TRIAS software has a long-term, positive side effect: Smarter planning effectively contributes to the reduction of CO2, nitrogen oxide and particulate matter emissions in cities.
Easy-to-use software solution
WPS contributes the intuitive frontend of the award-winning software ROADS (Roadwork Administration and Decision System) to the TRIAS software and PTV provides the powerful backend of the leading, multi-modal traffic flow simulation software PTV Visum.
When development on TRIAS began, WPS already had 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 second component of TRIAS, PTV Visum, models the traffic system of the city in order to analyse current problems and identify opportunities for optimisation.
For the first time, users from the municipal context are provided with an easy-to-understand and easy-to-use software solution that brings strategic roadwork 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 can be evaluated.
