Unobtrusive security and alternatives to bollards - Part 2

Last week I outlined why the problem of vehicular attacks on pedestrians demands thinking beyond target hardening. These incidents cannot be simply eradicated through design, but some of the alternatives below offer possibilities for reducing negative social impacts that accompany hyper-security.

OTHER OPTIONS

One way to avoid perpetuating fear and altering aesthetics of public spaces is to transform overt, obtrusive security to less visible (or invisible) security. Instead of fortressing our cities and increasing mass surveillance, target hardening practices can be integrated into the environment (e.g. street furniture, layout, paving styles, use of special materials).

Multiple cases of concrete bollards painted by local artists and activists show that citizens care about the appearance of their public spaces and the message they convey to their users. Other less obtrusive strategies include natural barriers such as rain gardens, ponds, bridges and Ha-Ha walls.

Simple, reinforced planters can provide security and image
Successful experiments have also demonstrated how altering pedestrian movement through playful and non-obtrusive designs such as floor markings and mirrors prompts people to use a designated safe route and foster their connection to both place and their users.

Congruent with the smart city movement, new invisible technical solutions are also possible. Sweden is now testing geo-fencing on a large scale before the country may be the first to implement this approach in a fight against heavy vehicles attacks. In the U.S., architects are designing safer schools.

Another popular option includes altering zoning practices in city centers such as special downtown zones that limit vehicle use to light-weight and slow-speed vehicles or pedestrian-only areas. Such zones have a life of their own. They provide opportunities for people to explore and enjoy them. Concurrently they help reclaim public space through reprogramming a restricted area into a positive land use. They also demand improved pedestrian infrastructure and street networks that support easy and safe movement.

Altered zoning practices can create pedestrian-only areas
The ideas about walkable and human scale design have culminated in practices such as the Barnes dance intersections. The World Resources Institute also provides a detailed overview of measures that prioritize a safe and human scale transport design.

FINAL THOUGHTS

Security professionals, designers and planners can balance security and socially-appropriate measures by providing safety and support connections as well as interactions between people. Obtrusive security measures divide and create barriers between people. There are better alternatives.

Rethinking bollards in public places - Part 1

Over the past few years, several western cities have seen an increase in attacks on pedestrians by vehicle ramming into masses of people. For example, New York's vehicle ramming last October that killed 8 people or the 2014 terror attack south of Montreal in which two Canadian soldiers were run down in a parking lot. 

In a bid to protect these soft targets, jurisdictions around the world have been installing concrete bollards and other hardened access control mechanisms. These measures intend to slow down or stop a vehicle or absorb an impact in the event of a crash. Some include:
  • Chicanes
  • Fortification through concrete bollards
  • Decorative planters, large rocks
  • Steel bollards (photo above)
  • Remote-controlled hydraulic barriers
  • Walls and hardened, bulletproof glass.

Although these design features are not new, they are instant reactionary solutions to vehicular attacks. As The National puts it: “the use of concrete blocks shows that cities have failed to incorporate effective anti-terrorist features, and are more for public reassurance”. Hyper-security measures neglect appropriateness and social acceptance. 

TARGET HARDENED PUBLIC SPACES

It might be too early to tell whether such measures prevent further attacks, but relying on obtrusive and defensive practices alone has already raised doubts about their appropriateness. Those doubts arise from feelings of false reassurance, unsightly bollards, and ugly aesthetics. Further, there are risks of displacement to more vulnerable targets and inadequate experience by designers and security officials while implementing high security, target hardening in public places.

In today’s high-risk society it is clear that something must be done to secure public safety. At the same time, target hardened solutions obsess on security at the expense of the democratic use of public spaces, what one author calls the paradox of democracy and hypersecurity.

Do these practices foster a culture of fear and alienation instead of a sense of security and kinship? We need to consider the impact of target hardened community spaces in the public realm, including freedom of movement and positive social interactions. The question is, What is the right balance?

Next week’s blog will provide some alternative practices for a better balance between security and socially-appropriate measures.

Cutting ram raids down under




I just attended the International Problem Oriented Policing conference in Providence, Rhode Island, the showcase for exceptional police work. Over 500 cops from all over the world gathered to share innovations for cutting crime.

This year's winner of the Herman Goldstein problem solving award was the property crime squad from New South Wales, the first-ever win by police in Australia. They tackled an epidemic of ATM "ram raids" in shopping malls. All over Sydney criminals are using vehicles to smash through mall doorways at night. They'd then ram ATM machines and drag them off to a safe location for looting.

This unique brand of theft and burglary is now world-wide. In Sydney it resulted in millions of dollars in theft and damage.

Their analysis showed access control bollards outside the mall doors were ineffective, yet no ram raids occurred where bollards were inside the mall at ATMs. That led to installing internal bollards across the city. They added enhanced reporting, crime prevention education, and other CPTED target hardening to improve their response. Within two years this cut the yearly number of incidents from 68 to zero.

A year later when offenders by-passed bollards and used sophisticated gas explosions to break into ATMs, police employed their analytical approach. In this case the private sector installed gas detection and disabling equipment. Again they cut the attacks to zero from a peak of 54. Except they did it in half the time.

We may not always be able to predict new crime methods. But when they arise, old solutions won't work. Analysis does. That’s why we insist CPTED practitioners spend more time in problem diagnosis and not waste time in guesswork.
