Hesse’s state capital of Wiesbaden has commissioned Siemens Mobility to implement its “Digitalization of Traffic” (DIGI-V) project, which is based on the city’s Green City Plan – Masterplan WI-Connect. Wiesbaden is lowering traffic-related nitrogen oxide emissions with an extensive air pollution control package covering all areas of mobility. To achieve this reduction in traffic-related emissions, extensive environmental and traffic data will be recorded, analysed and processed in real time.
Three different systems will work together to achieve traffic and environment-oriented simulation-based forecasting:
The three products exchange data; the data required for simulation-based prediction are transmitted on a permanent cycle. This process takes place automatically without any user interaction.
In conjunction with Aimsun Live, Concert is able to simulate the impact of different traffic management scenarios that involve one or a combination of the following traffic management strategies:
The traffic control room operator can manually activate the traffic management strategies available for simulation with immediate effect for up to 3 different scenarios.
After completion of the simulation, the system presents the operator with a comparison of the simulated scenarios with key performance indicators (KPIs) in order to communicate their effectiveness and usefulness in system optimization. KPIs communicate traffic and environmental situations.
In addition to the KPIs, the simulation produces a traffic score based on the traffic KPIs and a formula. The higher the rating, the more suitable the scenario is for implementation from a traffic management point of view. This formula and the KPIs to be considered must be defined in order to reflect Wiesbaden’s traffic management needs. In addition, the simulation provides an environmental assessment based on IMMIS. The higher the rating, the more environmentally friendly the scenario is for implementation.
