We study the traffic behavior when a vehicle changes from the first lane to the second lane on a two-lane highway. The incoming vehicle decelerates or accelerates by interacting with the vehicle ahead or behind on the second lane. We apply the extended optimal velocity model to the vehicular...

We study the multiple-vehicle collision when a vehicle changes from the first lane to the second lane on a two-lane highway. If a vehicle with high (low) speed on the first lane enters into the second lane, it may crash into the forward (rear) vehicle on the second lane and the crash may induce...

We study the multiple-vehicle collision when a vehicle decelerates suddenly in a single-lane traffic flow. The extended optimal velocity model is used for the vehicular motion to take into account the relative velocity. If a vehicle slows down suddenly and the following vehicle does not...
