A design has been chosen for the centre of the roundabout coming into Almonte and should be completed in the next couple of weeks. We are also continuing the process of reducing the number of signs.
The Ottawa Citizen has an interesting column today by Kelly Egan entitled “Taking the roundabout way to safer city streets”.
OTTAWA — Stop signs are not only stupid, they’re dangerous. So argues Gordon Whitehead, and rather persuasively. Think of the number of times, in your neighbourhood, you are forced by a stop sign to bring the car to a halt at a deserted intersection. Braking, looking, waiting, accelerating — more fuel, more pollution, wear and tear on the vehicle, more travel time — then do it again a block later, maybe at another deserted intersection. Repeat often, by the millions and millions, across the city, across North America.
In addition to the endless stops and starts, says the retired Ottawa resident, they’re an invitation to a collision. “Stop signs are an accident waiting to happen,” says the former air-traffic controller. “Someone, at some point, is not going to see it and sail right through.” Now throw in an entire enforcement regime, a veritable army of police officers, to make sure Mr. Harried Driver is not rolling through the stop at 2 km/h. Woaaah, there, skipper, that’s so dangerous!
Whitehead grew up in Britain, you might have guessed, and is a big fan of roundabouts, the common method of controlling traffic at intersections throughout Europe. Instead of stopping, vehicles at an intersection slow down and travel around a circular island. The roundabouts come in all shapes and sizes — from l’Arc de Triomphe in Paris, to the “minis” that are little more than built bumps in the centre of an intersection, but marked by lines. Last fall, Whitehead took a driving holiday through Britain, driving 1,356 kilometres in a rental car. “Do you know how many stop signs I ran into?” he asks. “None.”
Across North America, engineers and planners have come to accept what the Brits have known for decades: roundabouts are safer, cheaper, more efficient and environmentally friendlier than stop signs. There is something else to consider about these red hexagons. They are, in fact, more missable than intuition would lead us to believe.
There is some scientific evidence to suggest why. To wit. There was a well-known experiment done by a pair of researchers at the visual cognition lab at the University of Illinois about six years ago. They positioned six students in a circle — three in white shirts, three in black — and had them toss a basketball back and forth. Viewers were asked to count the passes. Part-way through the 75-second video, a person in a gorilla suit walks through the circle, beating its chest. When asked later, as many as half the viewers reported not seeing the gorilla, a phenomenon the psychologists call “inattentional blindness.” (In other words, if you’re tasked with one thing — looking for a street address, talking on the cellphone, changing the radio, fiddling with the GPS, combo of the above — you can easily miss the obvious other thing, like that red sign on a slender steel post.)
Roundabouts, though they may look chaotic, are actually safer than traffic-signal intersections, research has shown — reducing collisions by 36 to 40 per cent and fatalities by 90 per cent. Two factors are at play there: vehicles move slower and they don’t meet at right angles. Ottawa is actually turning the corner when it comes to roundabouts. There are now roughly 10 genuine roundabouts in the city, about half of them built in the last five years. And who would have thought Barrhaven would be the great incubator, with at least four and probably more on the way? Originally, Councillor Jan Harder was a skeptic, wondering if city staff were “crazy” to even suggest the idea to commuters accustomed to conventional traffic signalling. “But, I’ll tell you, it has worked better than anything I’ve ever seen.” Like many suburbs, Barrhaven endures a morning peak, then enjoys lighter traffic through the day. Stop signs didn’t serve the community well, she said — clogging traffic attempting to get onto arterials in the morning, then stopping the mid-day shopper on the way to the mall. The roundabouts, Harder says, keep traffic moving — all day. “It has worked out fantastically,” she said.
There is an issue with pedestrians, particularly school children and seniors, but those situations can be handled with proper design, she explained. City of Ottawa traffic program manager Greg Kent said council told staff to consider roundabouts when designing new intersections or upgrading older ones. The day is probably not near when older neighbourhoods will be retrofitted with them, however. Space is an issue, as is driver mindset. “We want public acceptance” before they are used at major intersections that use multiple lanes in the circle, he said. Shouldn’t be difficult. Less stopping on our busy roads? Sounds like a go.
