A mobile application for taking personal data at the place of accidents

The everyday life of a patrolman

Patrolmen are on the streets every day and contribute a large part to traffic safety. In 2019, the number of traffic accidents on German roads was around 2.7 million*. In addition to the actions taken at the scene of the accident, bureaucratic activities are an essential part of their work.

The challenge

In every traffic accident, personal data of the people involved and the circumstances of the accident are documented. This forms the basis for further investigations of the case. Digital applications are already available for case processing, but these are only used partially or not at all and many patrolmen still use pen and paper. This complicates the daily work and increases the bureaucratic part.

→ Multiple efforts in documenting the accident situation

The hand-written forms and preparation of the sketch must be transferred to a digital form. This leads to double processing and therefore takes a lot of time.

→ Existing smartphones are not ideally suited for data collection at the accident site

Using the smartphone requires a high level of concentration because the display is not large enough. As a result, attention is not being paid to what is happening at the place of use. Furthermore, there is no possibility to create a digital sketch.

The design process

To address the two main problems, a concept was developed in which the focus was placed on the two core functions of data acquisition and the creation of a digital sketch. For the concept, a solution in shape of a tablet application was designed and validated by several user tests.

Simplified recording of personal data

To record the personal data, the identity card is being scanned. By scanning the ID card, the person involved is automatically registered and the scanned personal data is added. The person is then attributed a role and the process can be repeated or completed.

↳ Personal data are filled in automatically

Preservation of evidence through a digital sketch

A sketch is created to capture the accident scene and to document it quickly. The GPS data of the accident site are used as a basis for mapping the course of the road at the accident location. A modular system is used to create the sketch. With this system, elements such as traffic signs, vehicles involved, etc. can be added to the drawing surface and also be edited.
