(1) Sleep until periodic  _timer expires

(2) For each in do

  (1) Read value.

  (2) Construct Decision Matrix (Dm) with position values using .

  (3) Analyze the Decision Matrix with Traffic Density (Td).

  (4) If () wants to perform Lane Change

    (1) Case: Inner to Outer:

      (1) If , and values are 0.

        (1) Lane change is Normal.

        (2) Set Dp as Normal.

      (2) else

        (1) Lane change is Abnormal.
