Two different versions of a pedestrian map of the centre of Delft have to be designed in such a way that it influences the behavior of the users. On each map a different walking route will be clearly recommended and the two versions will alternate every day.
On the image below there are shown different designs of the same route, clockwise and counterclockwise.

As can be seen, all the routes consist out of just one color. I have chosen to do so, so people won’t get distracted and confused by the use of various bright colors. It is important that the recommended route really stands out of the map, so I have chosen for a bright, pink color, but because this is the only flashing color on the route, the map itself is still clearly readable and the different icons and landmarks that we will use on the map won’t go unnoticed.
There are different ways to manipulate someone to take a certain route within the map.
But because the two different maps have to look similar on first sight, the differences between the two will have to be subtle.
On each of the six different designs of the route shown above, there can be seen that the route contains a gap on the cross-section. This will make people follow the route going forth in one piece, because that will be the most logical for them.
Of course a clear and well known way to show a direction is by using arrows, as are used in the two lower left corner designs. Another way to clearly make a certain direction visible is to start busy and slowly bring it down, like the two designs in the lower right corner, or to start big and slowly bring it down in size, like the footprint design in the upper right corner, or to start with a bright color and slowly make a gradient in it going to transparency.
When I look at the six different designs, the one in the upper left corner speaks the most to me. Because this route consists of just one piece and has the cleanest design, the map will look trustworthy and the route will not steel all the attention away from the rest of the map and all the icons and landmarks. But because of the bright color pink the route still stands out and it will become clear to every visitor of Delft which way they have to walk by following the route from bright color going to transparency.
