Underground Passageways


Identified Problem

Pedestrian underpasses are places that are often overlooked and perhaps even under utilised. While its purpose is to provide pedestrians the convenience of continuing their walking path despite blockages (i.e buildings/ highways), people tend to associate it with negative thoughts, and would often avoid certain underpasses due to the perceived unsafeness of the path.

There are various factors such as the lack of lighting, underpasses being isolated and quiet that contribute to the perceived safeness of the path.

Interview Questions

  1. On a day to day basis, would normally take pedestrian passageways?

  3. What are your feelings towards this passageway? Would you take this path? Why or why not?screen-shot-2016-10-24-at-2-51-13-pm
  4. Given that pedestrian underpasses provide a shorter route to your destination, would you rather go around or go through it?
  5. What would you suggest for the underpass so that it will be more pedestrian friendly?

What has been done


Left: Murals of SG in more touristy underpasses; as a culture identity/ to share our history with tourists, make the city a more vibrant place

Right: Commercial use for advertising, high traffic in prime shopping area, strategic exposure or the company


Left: Lights made the underpass a more inviting, welcoming space that changes color in 4 stages between dusk and dawn, adding a sense of life to their cityscape silhouette wall mural. This area had been previously plagued by vandalism.

Right: The split half effect by lighting and colour to differentiate the cycling and pedestrian path; the idea to distinguish the two different worlds of fast and slow traffic. Pedestrian path also has a ramp at the entrance whereas cycling path is flat (for user to differentiate)


  1. It is a challenge to change the negative perception of a space unless positive associations are made.
  2. Having a human company makes people more willing to travel through underpasses which they have a negative association with. It is also the most that can be done on the pedestrian level.
  3. Lighting and visual improvements changes perception first.

Problem Statement

Pedestrians needs a way to overcome the negative association that underpasses are unsafe or uncomfortable to travel by, in order to tap on the convenience of underpasses.
