Feasibility Analysis and Investigation of the User Acceptance of a Preventive Information System to Increase the Road Safety of Cyclists
This study aimed to investigate the user acceptance of a preventive Car-2-X communication warning system which could help drivers avoid potential collisions with cyclists. A User-Centered Design (UCD) process was used to develop a Human Machine Interface (HMI) as a warning system. Initially, an online survey (N = 153) was conducted to investigate user behavior and preference. To measure user acceptance, a 6-item survey on a 7-point Likert scale was conducted. User behavior was measured via 24 questions. Based on this, an HMI for the car driver was developed. The results of the acceptance score (M = 3.29) indicated rejection. However, most participants reported that they believe a system like this could improve road safety for cyclists. A functional prototype was developed and tested in a small field test. The results show that a 4G network and the GPS accuracy measured is sufficient for safety related applications.
