Lane change assistance system increase safety by providing warnings and other stability assistance to drivers to avert traffic dangers. In this contribution, lane change intention recognition was performed and applied to generate warnings for drivers to avoid eminent collision. Previous studies have not yet integrated driver's intended lane change actions as an input for determining when to warn drivers about eminent traffic dangers. Thus, if a driver's intended action may result in a collision, the driver should be warned in advance. In this contribution, lane change to left and right and lane keeping intentions were utilized to warn drivers of potential collision using an audio visual interface. The results indicate reduced risk of collision during lane change to left and right except lane keeping maneuvers. Moreover several participant feedback indicate an increased need for improved warnings by additional situational analysis that anticipate other vehicle behaviors such as intended lane changes.
