This intervention refers to the implication of clear sightlines in transport hubs and interchanges. Research revealed that the combination of limited access, a higher level of visibility, and natural surveillance in a train station environment, provides a heightened sense of security amongst travellers, discouraging misconduct. Thus, several early concepts were aimed to regulate the access and maximise visibility by incorporating those findings into the designs. Increased use of transparent materials enables ample natural light in sheltered areas and removes any potential hiding areas or blind spots, particularly around ticket machines where money handling is involved. Rational planning of entrances and exits provides railway stations with a more orderly flow of people with minimal opportunities for trouble. [2]

Sightlines need to be carefully designed in transit environments, with emphasis on the following characteristics:

• using ‘open’ fences rather than solid walls where possible, to enhance the potential for formal and informal surveillance [2,3]

• landscape design that does not provide places for people to hide, for example by using slow-growing shrubs that cannot grow too large, and prickly shrubs that minimise opportunities for concealment [2,3]

• creating clear sightlines by blocking off recesses, use of convex mirrors or wide pillars at corners, and use of clear glazing [2,3]
