TRANSPORT AND SECURITY activities might occur, should the environmental conditions offer opportunities to commit a crime. Architects and engineers can then work to "design out" the physical conditions that can result in crimes or poor security. "In security circles, this is known as crime prevention through environmental design or CPTED. This approach operates in the belief that the proper design and effective use of the built environment can lead to a reduction in the fear and incidence of crime, and an improvement of the quality of life," adds Foster. As a concept, CPTED is utilised by law enforcement agencies, planners, architects, security professionals and everyday citizens. The four underlying concepts that drive CPTED thinking are: 1. 2. 3. 4. Natural surveillance Natural access control Territorial reinforcement Maintenance "We know that in public spaces, criminal gangs are driven by behavioural patterns that focus on gaining what we call territorial control of an area. Terrorists are driven by being able to successfully stage major events, therefore surveillance is a critical deterrent as it takes away the anonymity of terrorists and their operatives," says Foster. "As cities grow and new facilities are delivered, Aurecon is being engaged to undertake security and risk assessments for places such as transport hubs and sporting, recreational and retail precincts," adds Foster. 43 Granger Bay Boulevard and Green Point Roundabout Traffic Circle, Cape Town, South Africa The Granger Bay Boulevard and Green Point Roundabout Traffic Circle, illustrates perfectly how design solutions have a direct impact on public safety and security. With the decision to site the 2010 FIFA World Cup™ Cape Town Stadium in Green Point, upgrades to local transportation infrastructure, particularly the Granger Bay Boulevard arterial road, became vital. Focusing on access/ egress and aesthetic appeal, the design and security challenge was to accommodate complicated and conflicting traffic, public transport and pedestrian flows. Aurecon's solution was to elevate the previously existing traffic circle/roundabout which allowed for the uninhibited flow of spectators to and from the stadium to the now famous Fanwalk to the City Centre and to bus stations. The complicated bridge structure was designed with slender, wineglass shaped columns to maximise visibility and safety. Rounded bridge parapets added to the aesthetic appeal and fulfilled an important safety function by opening up lines of sight and eliminating areas where people gathering were obscured from view.
