Objective: The purpose of this study is to investigate drivers" lane change behavior and decision making in congested traffic situations.
Background: Many traffic accidents occur when changing lanes. Drivers feel the risk of accidents during the lane change. It is necessary to reduce the workload of the driver by supporting lane change, especially in heavy traffic situations. Drivers" lane change behavior and decision making should be investigated as a basic study for the design of lane change support systems.
Method: The lane change situations in a large city with heavy traffic were videotaped and analyzed. The data measured before the lane change is the speed of the vehicle changing lane and the speed of the rear vehicle on the target lane. At the start of the lane change, the distance between the rear vehicle on the target lane and the vehicle changing lane was measured. In the lane change process, the speed of the lane change vehicle, the lane change distance, and the speed of the rear vehicle on the target lane were measured.
Results: In a congested situation, the speed of lane change showed a positive relationship with the distance of lane change. Also, the distance between the rear vehicle on the target lane and the lane change vehicle did not affect the driver"s speed decision. On the other hand, in a high risk of collision, the driver of the rear vehicle on the target lane performed defensive driving more actively than the driver of the lane change vehicle.
Conclusion: Under heavy traffic, the drivers of a lane change vehicle were speeding up during the long-distance lane change. For the safety reasons, they did not travel at high speeds over short distances. Drivers of lane-changing vehicles did not adjust the vehicle speed due to the lag gap, but adjusted the speed by the time to contact.
Application: The results of this research might help to develop driver support systems for the lane change.
