Operationalization of defined functionalities by the e-tools reviewed.

Functionality and how this is addressed by the e-tools in this scoping review		Tool references
Time autonomy: provide the option of choosing a departure date and time		[27,28,30-66]
Walkability
	Provide the option of minimizing distance or walking	[31,33,35,36,38,41,48,52,59,62,65,66]
	Store accessible routes for people with disabilities so these routes could be recommended for the next trip	[25]
	Consider the maximum distance tolerated by the user	[28,40,47,51,52,57,66]
	Consider the walking speed indicated by the use in route planning	[28,40,44-48,52,56,57,63,66]
Crowd avoidance
	Provide information about road traffic or parking	[38,39,47,49,50,54]
	Provide an estimate of the crowd on the bus	[38,61,63]
	Provide an estimate of the crowd at the destination	[38]
Incline avoidance
