Evaluation of driving behavior on highway entries

Merging onto highways is a demanding driving task with an above average number of accidents. Following the progress of developing automated driving systems, a specific system for this scenario could provide help. Within the scope of a study testing different automated driving behavior variations on the A9 highway, the manually driven highway entries were evaluated. The paper presents the first results derived from the highway entry in Lenting, Germany. The variables describe the participants' driving behavior in terms of cutting corners, velocities, decelerations, and accelerations. The two curves were cut with a maximum distance of 0.58 and 0.72 m from the center line. The velocities before the start of the entry zone were between 40-65 km/h and the mean velocity for the lane change was 76.95 km/h. The maximum lateral acceleration in both curves was around 3 m/s2 and the longitudinal acceleration was approximately between zero and 1.3 m/s2.
