Compared to the rest of Germany, Hamburg has a relatively low number of traffic accidents. That is why we need comprehensive data on traffic accident statistics as well as background information on Hamburg's urban and transport planning. This allows us to apply successful approaches to other cities and help improve their planning strategies. At the same time, the data also helps us optimize Hamburg itself by identifying accident numbers and causes in relation to the city's relatively small area, so we can work on further reducing traffic accidents.
