Campus safety - the fear vs risk paradox

Biomedical Research building, University of Toronto

GUEST BLOG

Novices to CPTED sometimes see things with a clarity others lack. Jennica Collette is a planning student at the Faculty of Environment at the University of Waterloo, Ontario. She and fellow students recently completed their first CPTED study. In this guest blog she summarizes their findings and comes to similar conclusions as reported by Harvard University design students in March.

As part of a University of Waterloo social planning class, a group of fellow students and myself wanted to know how urban form influenced safety, both actual and perceived. We chose university campuses, a context that was relevant and familiar, and compared our suburban campus at University of Waterloo to the urban campus at University of Toronto. It was our first CPTED experience.

We started by familiarizing ourselves with CPTED lingo including Oscar Newman’s Defensible Space Theory and Jane Jacob’s "eyes on the street". We looked at reported statistics and charts as well as perceived safety through site visits and random interviews. The results weren’t what we expected.

Initially we assumed the University of Toronto was less safe. Why? Perhaps the strong association between large urban centres and crime or the idea that people who don’t necessarily “belong” at the University can wander through the campus freely and easily. But during interviews we were told both campuses felt safe. Other than identifying some areas of concern, like poorly lit loading areas in Toronto or a woodlot trail in Waterloo, there were rarely moments where students felt like they were in any danger.

When we crunched the numbers we discovered, on a per student basis, there were more crimes at the University of Waterloo than the University of Toronto. Granted, both of these campuses experienced very few serious crimes, mostly petty theft and mischief, but there were simply more of them in Waterloo.

WHY?

One of the most significant differences between the University of Toronto and the University of Waterloo was the presence of people. Even during reading week Toronto’s campus was bustling with activity. In Waterloo, during the weekends and evenings, you could count the people on one hand.

Toronto’s safe environment can be attributed to a combination of multiple uses, permeable grid form and high densities. The Royal Ontario Museum, the Ontario Legislative building, and Queen’s Park all lie within the campus boundary and the grid form makes the campus as much a waypoint as a destination.

In Waterloo a ring road topped off with berms surrounds the campus. We were told buildings were oriented with crowd control in mind rather than legibility. All this makes the campus particularly unappealing for a visitor.

Does built form influence actual and perceived safety? Our first CPTED experience confirmed it does. What we found mostly is that there is so much more to safety than movement predictors and improving lighting (though that is part of it). From a planning perspective a large part of making environments safe is activating spaces and activating communities. It turns out that is also the conclusion of Second-generation CPTED.

Whether it a campus or residential neighbourhood, the key seems to be having people present who are engaged in their environments.

The street as classroom

  Evening CPTED audits - the city at night - photo by snowycactus
A few weeks ago a colleague of mine teaching at Harvard University asked if I would do a webinar with some planning and design students embarking on their first night-time CPTED field project. I talked with Benjamin Scheerbarth, Elise Baudon and Susan Nguyen about the myth and reality of CPTED and the difference between fear and risk; what residents' perceive versus what they actually experience. That's exactly what their research uncovered.

On one hand their observations suggested the area had "strong environmental design to prevent crime". Police on the audit confirmed "an overall safe downtown atmosphere with scattered incidents of [disorder]". On the other hand community members described fears of unsafe pockets and a sketchy area. Crime data suggested problems with theft and assault.

What to think? Who to believe? (I love conundrums like this for students!)

FEAR VS RISK

To the practitioner this is unsurprising. Crime geographers have been saying for some time that risk and fear are very different animals. One has a dangerous bite; the other frightens with a snarl. Yet it's impressive the students uncovered this so quickly.

To their credit the students dove deeper and discovered how events cluster around certain places and times (like bars at closing) and how to target solutions. Their recommendations spanned basic 1st Generation CPTED (better lighting, signage and cameras) and 2nd Generation CPTED  (diversified land uses, evening farmers markets, night-time community walks).

For a first time CPTED project, that's not bad. Not bad at all!

In the eye of the beholder


Fear and risk are two very different things. Solving one does not always solve the other.

I live in one of the most livable towns in the country. It has a variety of bookstores, an active and safe teen skate park, accommodation for the elderly, alternative housing options like cohousing, and two local industries.

There are over 40 restaurants for just 8,000 people (obviously a tourist town) and a festival every weekend from spring till winter. It has one of the most successful farmers markets and a vibrant and architecturally interesting downtown.

There hasn't been a murder in the city for decades and last year there were 52 violent crimes (mostly minor assaults) in the county with about 29,000 residents producing a county violence rate of 17 violent incidents per 100,000 residents.

In short, it is safe and vibrant.

Gotham City crime

New York City is also one of the most vibrant cities in the country and by every meaningful measure, it dwarfs my town. It has thousands of restaurants, bookstores, festivals, and every other amenity imaginable serving a city of over 8 million. It has a lower crime rate than most large cities. Yet, in comparison to my town the violent crime rate last year in NYC was 55 violent crimes per 100,000 residents.

In other words, the violent crime rate there was three times higher than here.

Yet a former neighbor, a young woman who lived in New York until recently, describes feeling much safer on New York streets than here. She is more concerned about walking home in the dark here than walking there even though her actual risk is 3 times higher (To be fair I doubt she knew the different rates, only how she felt).

Why?

The Truth about Risk

Perception and risk are two entirely different animals. I have spent many years working in high crime places. I learn about the cues of environment, attitude of the locals, and actual crime risks. My first lesson - we may feel safe but not be so.

This week I read a great blog about crime risk by Sam Harris titled The Truth about Violence. He cites four basic safety principles including how to avoid dangerous places and people.

Harris also describes a truism about us: It is unpleasant to study the details of crime and violence—and for this reason many of us never do. I am convinced, however, that some planning and preparation can greatly reduce a person’s risk.

I agree.

Read Harris's blog. It's worthwhile.
