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.

CCTV marries A.I.


Who will keep watch in isolated places?

I have been pondering security technology encroachments into public life, particularly regarding CCTV monitoring. There was a time, it seems now very long ago, that the UK began installing CCTV. Hundreds of millions of dollars, and over four million (and counting) CCTV cameras later, the UK is the most surveilled society on earth.

We were assured that would never happen in the US, or other developed countries. Violate our civil rights? No way cried the libertarian and democratic pundits in unison. 

Still, if you have nothing to hide…

Today, London and Beijing have over 400,000 CCTV each (proving politics is no guarantee either way). In the US there are over 30 million CCTV cameras, mostly in private hands. But there are now CCTV on streets in every major US city (Houston and Chicago lead the way with over 14,000 in Chicago alone) and public support is growing.


Will the brain behind the camera soon be an intelligent computer?

APPLAUDING OR BOOING?

On one hand, we applaud when police apprehend the Boston terrorists due in large measure to public CCTV. We also later watched those same terrorists as they planted and exploded the devices - prevention was not a result of those cameras. 

I always applaud traffic intersection CCTV to cut car crashes, especially in my city where drivers spend more time in narcissistic self-obsession trying to beat the red light rather than watching where they are going. 


CCTV in public spaces is not new

THE NEW REALITY

Recently I’ve been reviewing the latest in CCTV analytics, intelligent tracking and real-time scene analysis. In other words, CCTV on steroids. The latest is no longer motion detection or auto tracking (so old school). The latest is intelligent video analytics, a major evolution from facial recognition software of yesteryear. Video analytics is made possible by exponential increases in processing power and so-called ‘intelligent’ algorithms. 

And now it is part of security and public safety, watching for suspicious movements, packages, behaviors. Watching you! How does the computer know what to look for? It uses algorithms based on past behavior. In future, it may use artificial intelligence to learn on its own. And that is where things get interesting.

Wired magazine puts it this way:
“voice, image, and motion recognition will transform human-computer interfaces into a seamless interaction between the user and all the computing devices in that person’s life.”
A few years ago I blogged about economic theorist Jeremy Rifkin, his forecasts, the Internet of Things and his predictions for disruptive technologies. It seems he was right. Should we be worried?
