- Thickness of the route lines
- Curved or straight edges where a line changes direction
- Station markers: if they should be ticks, dots or some other visual elements
- Legible, simple typeface
Geographical transit maps are better suited as bus maps because they give the commuter a general idea of which direction the bus is heading toward. The maps should be a simplified version of the actual maps of bus routes, this also helps the commuters to easily identify the journey.
We simplified the routes of NTU, leaving the necessary curves and general shape of the school. This is to cater to the people who are inclined to following route shapes on vehicles.
The route lines are thick and easy to spot. Contrasting colours are used. Bus stops that the blue buses stop at are in light blue, bus stops that red buses stop at are in pink. The other buses that exist but are not in the shuttle bus routes are also indicated because some people uses counting of bus stops as a means to identify where to stop.
We also tried to ensure that the route lines in our maps do not overlap with each other, so that they are to be easily traceable and distinct to the eye. (The fact that NTU is in a roundish shape helps with that.) However, there were several instances where we had to do it because of the direction of the routes and the roads. (The brown campus rider had to be modified to over lap because otherwise the road directions don’t make sense. This is to cater to those who are inclined toward directions and route shapes.)
It is also necessary that there is a lot of space for the text so that it is clearly seen. We took into account the fact that some people would look out for necessary land marks as a guide, and we thought of how we would like to include a universal landmark that everyone would know i.e. the roundabouts. This way, everyone would be able to understand the landmarks as shown. We also have (generally) famous landmarks of NTU on the maps.
We also shortened the names of the buses to the colour themselves, because CL-R, CL-B, CR, CWR were just too confusing. (We feedback to the SU too, and they took up our advice!)
(This was our initial design, without feedback from class yet.)
