Passing Behavior Analysis at at Additional Lane on Two-Lane Highway and Consideration of effective additional lane installation
Kazushi Sano , Hiroaki Nishiuchi
We have developed a passing behavior model at additional lane on two-lane highway.
We conducted a survey to measure spot velocity of driving vehicles by using video cameras on Ban-Etsu Expressway and estimated their trajectory on time space diagram by using spline function.
We assumed that a car drove at its desire speed in case of free driving and a car judged passing or not considering the difference between desire speed of the previous vehicle and of its own and the distance to the end of the additional lane.
We estimated parameters of the model to minimize the difference of the order of cars between the actual data and estimated by the model and confirmed that the reproductively had improved by changing the passing judgment to consider the behaviors of the two or more passed cars.
Using the model and estimated parameters were constructed to examine the optimum additional lane installation according to traffic volume.
As an evaluation index a passing number of times according to the desired speed, while changing the additional lane length and number of vehicles in one vehicle group, to perform the simulation
