Disruption Recovery in sub-Second
WEIVI solves the optimal traffic disruption recovery plans for reasoned decision making and recovery implementation. It computes updated schedules, locations and velocity profiles based on real-time information about events and disruptions.
Carbon Emission Management
WEIVI can evaluate environmental impact of railway traffic in terms of CO₂ emissions.
Energy Optimisation
WEIVI optimises train velocities based on train physics and updated schedules, ensuring minimal energy consumption.
Easy Network Import
WEIVI is compatible with any traffic control standard or traffic management system.
Functionalities
Optimisation in Disruptions
WEIVI computes the optimal operational plans for the trains and updates schedules, locations and velocities based on real-time train traffic data and information about events and disruptions.
Train Connectivity
WEIVI includes the interdependencies between trains (e.g., connecting trains that are operated with the same rolling stock). Accurate train physics with, e.g., railway’s vertical geometry ensures realistic simulations including interactions with control and signalling systems.
User control
WEIVI allows careful manual event and issue adjustment for traffic controllers. Moreover, adjusting simulation environmental parameters like flow of simulation time and returning to past events is possible. It also supports selection of parameter weights in optimisation value function.
Assisting system
WEIVI enhances human decision making in TMS-systems.

Predictive Digital
Twin Technology
WEIVI’s technology stands out by pioneering unique predictive features that enhance the simulation capabilities of digital twins. Predictive digital twins are optimal in solving complex traffic management problems efficiently.
Train Physics
WEIVI’s advanced train physics produces accurate velocity profiles that can be used even in autonomous train driving. It can utilise vast group of parameters including vertical geometry and curvature of tracks, effects of weather and ballistic coefficients of trains.

Graphical User Interface (GUI)
Depicts the traffic and forecasts as a graphical timetable. Allows for easy adjustments and manual inputs, ensuring the optimisation software can be used even without real time traffic data. Also makes it possible to test infrastructure models and timetables to plan and evaluate the effects of infrastructural implementations. The graphical user interface (GUI) acts as an input/output (I/O) interface.
