This means further enhancing its attractiveness as an employer to ensure long-term employee loyalty and recruit well-qualified new staff. Key levers here are ongoing development of new working time and remuneration models, attractive career prospects and a working atmosphere in which employees can feel at home and give their best. To help achieve these things, a HOCHBAHN-wide project entitled “Reconciling work, family and leisure time” has been set up among other measures. One aspect which cuts across all these six fields of action is digitalisation. The idea of “intelligent mobility“ is increasingly inseparable from the digitalisation of life. For the HOCHBAHN as an efficient provider of mobility options, the digital processing of analogue information already today opens up a plethora of new possibilities: processes within the company can be organised more efficiently and optimised. At the same time digital data helps the HOCHBAHN to adapt its day-to-day activities more closely to the needs of its customers. In the role of central mobility provider, the HOCHBAHN is helping to shape the establishment of a networked, intelligent traffic control system in the city. The utilisation of public transport capacity can be planned better and the deployment of resources organised much more efficiently in this way. A wide range of dynamically changing transport information can be made available to passengers, and electronic ticketing systems make it easier to choose the best tariff. The HOCHBAHN is taking up the challenge of using the opportunities presented by digitalisation in the best way possible to build, together with the City of Hamburg and its other mobility partners, an easy-to-use, individualised, flexible and sustainable mobility system for the future. 1.3 Research and development The Federal Government adopted an Electromobility Law in the autumn of 2015. Since that time, the Hamburg Senate has implemented concrete measures to promote the use of electric vehicles in the city. Thus it is planned, for example, to expand the recharging infrastructure on public streets to 600 charging points. As of the end of 2015, some 1,800 electric cars were registered in Hamburg. With a fleet of 40 e-cars, the HOCHBAHN itself is one of the most active users in Hamburg. Prices for petrol and diesel fell to a historically low level during the year under review. Irrespective of this fact, finding substitutes for fossil fuels and switching to public transport remain a major goal of Hamburg’s climate policy. The HOCHBAHN is advancing this development with the ongoing procurement of buses with state-of-the-art exhaust aftertreatment systems to reduce nitrogen oxide and particulate matter emissions. 18

Annual Report 2015 According to current plans, all HOCHBAHN buses will comply with the requirements of the Euro Norms 5 or 6 by 2018. With meanwhile approximately 60 hybrid propulsion buses, which enable fuel savings of up to 20 % compared with conventional diesel buses, the HOCHBAHN and its subsidiaries are making a lasting contribution to protecting the climate. In addition to air pollutants such as nitrogen oxides and particulate matter, in order to also reduce the climate killer carbon dioxide as well as noise levels, it is imperative to switch over to electrically driven buses. This is also in line with the political remit to procure only zero-emission buses from 2020 onwards. For this reason, the HOCHBAHN is supporting bus manufacturers such as Daimler Buses or Volvo in the framework of strategic partnerships to develop electric bus propulsion systems and to adapt them in a precisely targeted way to the needs of regular bus operations. The insights gained above all from the operation of the Innovation Line 109 are invaluable, since they enable all those vehicle concepts which seem promising today to be evaluated on a level playing field. Currently all the bus makers are working on developing innovative bus drives up to series production maturity. Recognisable progress is being made here in major components, for example in the storage density of batteries. Nevertheless, it is not possible at present to form any conclusive evaluation as to which propulsion or energy storage system will prevail. While battery buses are characterised by high efficiency and low energy costs, fuel cell buses have the edge in greater range and higher flexibility and productivity. As part of a scientific cooperation programme with the Fraunhofer Institut für Verkehrs- und Infrastruktursysteme (IVI), the HOCHBAHN is currently examining how far the experience gained with the Innovation Line 109 can be transferred to partial networks or all bus routes of the HOCHBAHN. In 2015, the HOCHBAHN also cooperated with the Institut für Stadt - und Kulturraumforschung (IfSK) at the Leuphana University in Lüneburg with the aim of compiling a scientifically substantiated basis to evaluate the environmental performance of the HOCHBAHN. As a result, parameters were defined to describe the relevant relationship between the choice of transport form and the environmental effects in the dimensions of sound generation, area affected and air. The services run by the HOCHBAHN provide relief for Hamburg equivalent to approx. 409,000 cars per day, thus avoiding emissions of the greenhouse gas carbon dioxide from cars of some 159 milligrams per person and kilometre. These findings underline the major contribution made by HOCHBAHN services to securing the quality of life in Hamburg. 19
