But mobility has its price – traffic jams, exhaust emissions, noise and accidents with material damage and sometimes serious personal injury. This is why an integral approach is so urgently required for making road traffic better and safer. Accidents 16 Acute Risk of Missing EU Targets for 2020 When it comes to road accidents with casualties, car occupants account for the highest number of fatalities and injuries. In Germany alone in 2014, almost 50% of all people killed on the roads were occupants of a car; among those suffering minor and serious injuries, this figure was more than 55%. Examples of Accidents/ 30 Compelling Examples of Accidents in Detail Crash Tests Eight selected incidents The Human Factor 36 Paying Attention Is the Best Safety Strategy Whatever mode of transport you use, road accidents generally have multiple caus- es – above all, excessive speed, inattention or alcohol. The person at the wheel is the biggest risk factor, which is why our attention must also be focused on people if we want to make our roads even safer. Vehicle Technology 46 Saving Lives Through Technical Safety The EU Commission’s objective is to have next to no more traffic fatalities on Europe’s roads by 2050. To achieve this goal, the focus needs to be on not only driver assis- tance systems such as ESP but also, increasingly, the next levels, that is, automated driving systems Infrastructure 58 Well-Maintained Roads Are Key In addition to in-vehicle passive, active and integral safety systems, compliance with traffic rules and correct behavior on the roads, the infrastructure also makes a key contribution to road safety. Summary 64 A Clear Goal: Let’s Get Back onto the Road to Success Although the risk of suffering fatal or serious injuries in passenger transportation has decreased significantly over the past few decades in nearly every EU member state, we must not rest on our laurels when it comes to the efforts to improve road safety even further. As this report has demonstrated in the preceding chapters, action still needs to be taken in a number of areas. Contacts 66 Any Questions?

Introduction Safely into the Future The majority of traffic can still be found on our roads, a fact driven by not only globalization of the manufacturing econo- my but also increasing mobility in both our professional and private lives. But mobility has its price – traffic jams, exhaust emissions, noise and accidents with material damage and sometimes serious – even fatal – injury. This is why an integral approach is so urgently required for making road traffic better and safer. Automated driving and Mobility 4.0 can help to lay important foundations for this. W hether by car, motorcycle, moped, pedelec, bicycle, public transport – buses, trains and airplanes – or on foot, “passenger transportation” For decades, cars have accounted for by far the highest amount of passenger kilometers traveled by any mode of transport.

Introduction frastructure), these technologies can also help to further reduce the number of accident-critical sit- uations and, in turn, the number of serious acci- dents resulting in death and serious injury. Already today, some vehicles are semi-auto- mated and networked. In the future, the number of vehicles featuring automated driving and net- working functions will increase significantly. For road traffic, a number of digital “test fields” are currently being set up in Germany. One of these is a stretch of A9 Autobahn in Bavaria (“Auto- bahn 4.0”), on which partial and highly automat- ed driving – and, looking ahead, even fully auto- matic driving from time to time – is to be trialled.

Accidents Acute Risk of Missing Eu Targets for 2020 When it comes to road accidents with casualties, car occupants account for the highest number of fatalities and injuries. In Germany alone in 2014, almost 50% of all people killed on the roads were occupants of a car; among those suffering minor and serious injuries, this figure was more than 55%. Furthermore, almost two thirds of all people involved in acci- dents with casualties were car drivers. And things don’t look much different EU-wide, which is due no doubt to cars’ sheer dominance on the roads – more than half of all journeys are made by car. However, the figures also show that, in terms of mobility behavior, this vehicle category and its users still offer the biggest potential for initiating a disctinctive downturn in the number of road accident victims. At the same time, the number of vulnerable road users such as riders of two-wheeled vehicles and pedestrians is also increasing, which means that even more attention must be devoted to these road user groups in the future. Demographic change also ultimately gives rise to additional challenges. T he judgment of Violeta Bulc, the EU Commis- sioner for Transport, at a press conference last year in Brussels could hardly have been more sober- ally bad year for road safety, particularly in terms of the unfavorable development compared with 2013. Although the number of traffic fatalities fell by 1.2% ing when she stated that, in her view, 2014 was a re- to around 25,700, this percentage decline was a long way from the fall needed to achieve the European Commission’s strategic goal of halving the number 8 Road traffic fatalities in EU-28 since 1991 of traffic fatalities between 2010 and 2020. In figures, The sustained downward trend is unmistakable, although it has clearly lost momentum in 2014. this would mean that the number of traffic fatalities on Europe’s roads would have to be less than 16,000 2 in 2020. This would be just about possible with a per- 80,000 centage decline of around 7.8%, as was the case from 0 2012 to 2013 (Figure 8).
