Lane Change Behavior on Freeways: An Online Survey Using Video Clips

Table 2

Overview of the questions: screenshot (all but the first row cropped due to space limitation), question number, theme of question (in bold), and description.

1: Right overtaking. You are driving in a tunnel on a 4-lane freeway on the third lane from the left. A truck is driving up ahead in the rightmost lane and a person car is driving in the second lane from the left while there is space for that driver to keep right using your lane. You are getting closer to that person car.	2: Strategies 1, 2, and 3. You are driving on a 3-lane freeway in the right lane. A slightly slower predecessor is driving in front of you and you are approaching that vehicle, while a black car just passed you with high speed.	3: Strategies 1, 2, and 3. You are overtaking the white car, which increases its speed a bit, resulting in a very slow overtaking maneuver (this scenario is only shown to the respondents who want to overtake the vehicle with a constant speed).
4: Strategies 1, 2, and 3. You are driving on a 2-lane freeway during congestion in the left lane. You are approaching the tail of a stop-and-go wave, while traffic in the right lane drives smoother and with a higher speed.	5: Right overtaking. You just entered the freeway via an on-ramp, while in the lane to the left of you a black car is driving with a low speed. You need to proceed on this carriageway to follow your route.	6: Strategies 1, 2, and 3. You merge onto the main road from an on-ramp, while to continue your route you need to take the second exit from that point which is 3100 meters up ahead.
7: Keep right/Strategy 4. You are driving on a 3-lane freeway in the center lane while having passed a truck in the right lane. There is space to change lanes to the right after you have passed the truck, while a faster driver is approaching you from behind.	8: Keep right. You are driving on a 3-lane freeway in the center lane, while passing two trucks in the right lane. After you have passed the trucks there is an empty road ahead of you.	9: Strategies 1, 2, and 3. You are driving on a 3-lane freeway in the rightmost lane. A truck is driving in front of you in the same lane, while a faster driver is approaching you from behind on the center lane.
10: Keep right. You are driving on a 2-lane freeway in the left lane, while you pass a truck that is driving in the right lane. Up ahead another truck is driving there, while a faster driver is approaching you from behind.	11: Strategy 4. You are driving on a 3-lane freeway in the rightmost lane with a speed of 100 km/h. However, all other vehicles around you drive much faster and you are overtaken by them.	12: Courtesy lane change. You are driving on a 2-lane freeway in the right lane, while you approach a merging lane on which a vehicle is driving. However, the driver is not using its blinker.
13: Strategies 1, 2, and 3. You are driving on a 3-lane freeway in the center lane. To follow your route you have to take the exit that starts at 600 meters from the moment the video stops. On that moment a truck is driving ahead in the right lane.	14: Keep right. (Static picture). You are driving on a 3-lane freeway in the rightmost normal lane. This road section is equipped with a rush-hour lane which is currently open for traffic. You will pass the truck that drives on the rush-hour lane.
