Improving the safety of pedestrians by using a cooperative system

The number of traffic accidents with injury to persons is still too high. Hence, it is an important question, how the number of accidents with pedestrians can be reduced. We propose to integrate existing technologies and mobile devices into a cooperative system which is able to detect critical situations and execute preventive counteractive measures such as warn traffic participants. The paper starts with an analysis of the different types of accidents in a detailed accident study using the GIDAS database and reports of local accidents with pedestrians. With regard to the different types of accidents it is important to consider the reasons for each situation. The obtained knowledge is used to build general scenarios to determine on effective means to prevent such accidents. Finally, three different system architectures with varying level of capabilities and complexity are designed.
