BERLIN, GERMANY

By 2030, Berlin's entire fleet of more than 1,400 buses will be completely electrical. For efficient vehicle workings, BVG relies on IVU.suite’s optimisation tools.

CREATE OPTIMAL TIMETABLES AND VEHICLE SCHEDULES


INTEGRATED TIMETABLE PLANNING

IVU.suite stores all relevant data about the network, including information about terrain or infrastructure data such as charging possibilities. Automatically linked to the battery and consumption profiles of each vehicle type and route section, the system provides planners with a comprehensive overview of their network. In addition, IVU.suite indicates if routes are unsuitable for battery-powered electric buses, thus supporting the respective decision-making processes.

RANGE FORECAST

Machine learning inside: To help planners create the optimum vehicle working for every vehicle type, IVU.suite has learning capabilities. The system knows the power consumption of the different electric bus models as well as the age of their batteries from which it determines a forecast of the expected range.

To deliver a result that is as exact as possible, the algorithms use real data from the completed trips. In this case, details about the vehicle along with relevant environmental factors such as topography, outside temperature, number of passengers or traffic situation are incorporated in the calculations. If little or no data is available, for example because not enough electric buses are operating yet or a vehicle working is new, the system determines the likely energy consumption for the individual vehicle workings based on simulation models.

Scheduling charging processes

The planning process for vehicle workings for battery-powered electric buses must also take charging times into account. That’s why vehicle working scheduling in IVU.suite makes it possible to create the necessary charging processes at the same time. Based on anticipated energy consumption for different vehicle types as well as the existing infrastructure, such as the number of charging stations in the depot and their availability, the system enables the creation of suitably sized charging time windows right at the planning stage.

The software also closely monitors total charging capacity to ensure, on the one hand, that upper power limits and locking periods are adhered to, but also that all vehicles are sufficiently charged. If necessary, planners can even assign parking spaces and charging stations as part of the vehicle working scheduling. Specific activities such as preconditioning can also be conveniently entered in the system. The end product is a complete charging plan that includes the intended charging duration as well as the planned charging curve. The charging plan is also available to the vehicle dispatch, operations monitoring and depot manage­ment departments along with other areas of work. This guarantees a seamless flow of data and ensures a standardised planning and dispatch process.
