A key feature of future local public transportation will be the networking of different means and facilities of transport, including e-bikes, car-sharing, rail systems, and road transport. Some areas in the world are already building such networks. Buses will play a key role in this development. And that is not only because they already account for over 46 percent of local public transportation and therefore serve as its backbone. In addition, buses are unbeatable when it comes to safety, environmental compatibility, sustainability, economic efficiency, and flexibility. Germany’s Federal Environment Agency, for example, has determined that travel coaches consume only 1.4 liters of diesel per person and 100 kilometers on average, which translates into 31 grams of CO2 per person and kilometer. As a result, travel coaches are the undisputed “champions” for low emissions — way ahead of trains, cars, and planes. The situation is similar with regular-service buses in local public transportation. Resource-conserving drive systems are one of the factors contributing to sustainable mobility, and such systems are already available as standard equipment in buses today or are undergoing testing. They include buses with BlueTec diesel technology, regular-service buses with natural gas engines, diesel hybrid buses, and zero-emission fuel cell hybrid buses. In addition to alternative drive systems, alternative fuels are also being tested for use in buses.
