Road-Type Classification with Deep AutoEncoder

Algorithm 2

Feature generation for each road segment.

	Require: and
	Output: Feature vector for each road segment
(1)	for each road segment do
(2)	Obtain the length of from .
(3)	Compute midpoint coordinates of .
(4)	Obtain geometry of .
(5)	if does not have a geometry then
(6)	Convert to line geometry.
(7)	Divide into 20 equally spaced distanced points .
(8)	for to 20 do
(9)	Subtract by midpoint coordinates .
(10)	end for
(11)	else
(12)	Divide geometry into 20 equally spaced distanced points .
(13)	for to 20 do
(14)	Subtract by midpoint coordinates .
(15)	end for
(16)	end if
(17)	Obtain one hot encoded vector of the speed limits with standard values.
(18)	Concatenate features generated from steps 2 to 17.
(19)	end for
