- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

Safety4Bikes : Assistance Systems for Cycling Children to Increase Safety

Konferensbidrag (refereegranskat)abstract
- Cycling is a popular urban mobility solution. However, cyclists are more vulnerable and relatively unprotected compared to other road users. In Germany, the number of accidents withcycling children increases dramatically from age 8 to 14. This is not least due to their insufficient cycling skills and understanding of traffic, which is a detriment to their safety. The project Safety4Bikes, which is funded by the German Federal Ministry of Education and Research(BMBF), grant no 16SV7669, aims at mitigating the risk of young cyclists by developing appropriate modular assistance systems that detect situational hazards and promote safe behaviour. Within the project, we are developing novel visual, tactile and acoustic signals integrated in bicycles and helmets to convey information for children in an understandable andnon-distracting way. Embedding the cyclist into the surrounding context, we develop andinvestigate sensor technologies, algorithms and routing strategies needed for identificationof the behaviour of cyclists on the road, traffic signs, safest routes and trajectory corrections.Additionally, we focus on the enhancements of Car2X communication to enable the exchange of information with other vehicles. The project follows a user centric approach inwhich the developed system components are continuously tested and adapted to the needsand characteristics of the target group. Answering the question of how the components willhave to interact with the user is an important part of the research. Therefore, we evaluate theefficacy of the designed interaction and recognition methods as well as sensors, algorithmsand routing strategies through laboratory experiments and bicycle simulators. With controlled test-track experiments on a test route, the components are further evaluated and optimised.

- Cycling safety gestures, such as hand signals and shoulder checks, are an essential part of safe manoeuvring on the road. Child cyclists, in particular, might have difficulties performing safety gestures on the road or even forget about them, given the lack of cycling experience, road distractions and differences in motor and perceptual-motor abilities compared with adults. To support them, we designed two methods to remind about safety gestures while cycling. The first method employs an icon-based reminder in heads-up display (HUD) glasses and the second combines vibration on the handlebar and ambient light in the helmet. We investigated the performance of both methods in a controlled test-track experiment with 18 children using a mid-size tricycle, augmented with a set of sensors to recognize children's behavior in real time. We found that both systems are successful in reminding children about safety gestures and have their unique advantages and disadvantages.
