The goal of this paper is to state and evaluate the differences in gap acceptance observations between left lane and right lane change, and experiment overall aggressiveness by the means of right lanechange behaviors and use of electrical instruments for reaching this goal, furthermore we use Digital SignalProcessing on our controlling cameras to be able to distinguish different behaviours of drivers. Also, in this paper we evaluate the decision making process of drivers, we do this work with use of electrical sensors for accumulating some data and clarifying and processing them and finally with use of cumulative distributionfunctions of driver lane change behaviours from the observed field data. These experiments are performedfor drivers using I-20 in Grand Prairie, Texas with the roadside controlling cameras and some other electronical controlling instruments which were amounted near the intersection of I-20 and Great Southwest Blvd. Our experiments and evaluations demonstrates, that the whole ratio of right lane change observations to left lane change observations was close to 3 to 1.
