E-mobility in public transport
IT-TRANS 2020: Exhibitors present digital solutions for urban mobility (Part 4)
Using buses with electric drives rather than conventional combustion engines would reduce noise pollution as well as cutting down substantially on emissions that are harmful for the climate and human health. As Martin Schmitz, Technical Director of the Association of German Transport Companies (VDV), which has more than 600 member companies from the public passenger and rail freight transport sector, explains: “Around 315 electric buses are currently being used in Germany, with a further 750 on order. However, the difficulties involved in supplying power to depots and getting approval for building charging infrastructure in densely built-up urban areas are continuing to hamper the switch to e-mobility. After all, as well as the vehicles themselves, it is primarily a question of infrastructure and new operational processes.”
Range calculation takes into account weather conditions, traffic jams and route characteristics
Swiss company Trapeze is showcasing special solutions for e-bus fleets at IT-TRANS. The Trapeze Smart Monitor allows the vehicle status to be monitored. The system provides real-time information on all the available vehicle data such as battery charge level and possible range in hours or kilometers. The technical status of the vehicle is also recorded automatically and communicated to control room and workshop. The ongoing range calculation additionally takes into account factors influencing energy consumption such as weather conditions, uphill and downhill sections and repeated stopping and starting on account of traffic jams and diversions. In this way, the smart software solution simplifies operational processes, making it possible to plan vehicle deployment more efficiently, to exclude range risks and also to reduce operating costs by optimizing workshop processes and maintenance.
E-mobile ride pooling with Via
ViaVan is re-engineering public transit, from a regulated system of rigid routes and schedules to a fully dynamic, on-demand network. ViaVan’s BerlKönig service, in partnership with the Berliner Verkehrsbetriebe (BVG), is the largest public sector on-demand ride pooling project. Around half the fleet comprises electric vehicles, for which Via has developed new charge tracking algorithm, allowing drivers to see when they need to charge the vehicle. The New York based company has also developed comprehensive planning tools which ensure that despite charging cycles and vehicle replacements the service is never undersupplied in its operating area. The BerlKönig project won the 2019 Public and Urban Transport Strategy Award sponsored by the International Association of Public Transport (UITP). UITP is a co-organizer of IT-TRANS.
IVU.suite combines all vehicles in one interface
The IVU.suite enables operational factors such as charge management and charging times, ranges, route lengths, overnight and opportunity charging to be optimized, and electric buses to be seamlessly integrated in planning, scheduling and control. IVU.rail, the integrated standard system for railways, helps to make efficient use of rolling stock. The vehicle and maintenance optimization system automatically takes into account predetermined service intervals and planned maintenance. In the event of a fault, a suggestion function recommends a suitable replacement vehicles and routes. IVU.rail also optimizes personnel deployment. The IVU.crew planning solution provides support in all personnel deployments and ensures that employees are where they are needed.
Coverage monitoring facilitates efficient use of resources
Verkehrsautomatisierung Berlin GmbH (VAB) also supports intelligent and demand-driven planning for e-bus fleets with IT solutions. The objectives are fast handling capabilities in daily operations and a reduction in administrative effort. Electromobility influences numerous operational processes at the depot and in the route network. VAB’s smart charging management solution in combination with range monitoring ensures eco-friendly and efficient use of resources. Proven technologies can be seamlessly integrated for preconditioning vehicles, for example in the form of demand-led control of vehicle preheating.
Data-based decisions for information and cost transparency
Pure Vision Systems is consistently focusing on big data throughout its line of products and services, thus keeping public transport future proof and competitive. Typical applications include continuous recording of vehicle positions and meta data, information on fuel consumption and routes driven (relevant for e-mobility applications) and the creation of the basis for differentiated controlling. Data from all the on-board vehicle systems such as IBIS, passenger counting systems and vehicle CAN are recorded synchronously on the central system platform, processed and forwarded to backend systems. Depending on intended data usage, the data is processed either in real time or transferred to backend systems using block transfer.
