Comparative Analysis of Travel Patterns from Cellular Network Data and an Urban Travel Demand Model

Algorithm 1

Stop detection as used by the STOP trip extraction algorithm. A stop ends once the next position is not in distance of all positions belonging to the current stop (L).

	Data: user position for every minute
	Result: list of stops S
	; ; / Initialize with stop /
	for each do
	if then / Within distance? /
	; ; / Stop continues /
	else
	if then / Stop long enough? /
	; /Save valid stop /
	end
	; ; ; /Start new stop /
	end
	end
