In the TM app, when plotting a temporary one way street, instead of the standard one way symbol being shown on the map, allow for this to be rotated in the direction of the one way, or have arrows plotted indicating the direction to be shown along the line. Currently, the public do not know which way a one way is in place unless written in the description, which they don't always read.
I cannot see a valid reason why you will not implement changing your icon to show the direction of travel
