Algorithm 1
Purpose:	obtaining a safe route to go from an origin point to a destination point
Inputs:	origin and destination points
Output:	representation of the route on a city map and guidance of the user’s safe route
1:	routePoints ← get the default route (origin, destination)
2:	pedestrianPoints ← pedestrian areas near to the route (routePoints)
3:	if size (pedestrianPoints) ≠ 0
4:	optimizedRoute = false
5:	repeat
6:	routePoints ← route optimization (origin, destination, pedestrianPoints)
7:	pedestrianPoints ← calculation of new pedestrian points near to the route (routePoints)
8:	if size(pedestrianPoints) = 0
9:	optimizedRoute = true
10:	end if
11:	until (!optimizedRoute)
12:	end if
13:	trace safe route on city map
14:	highlight the safe pedestrian points included in the route by means of a special icon
