OPINION - Traffic Calming
Traffic Calming in my opinion is a good idea on paper but mostly ineffective in reality. Many municipalities are starting Traffic Calming measures however few are successful in achieving what is effective.
One of my nearby municipalities, the Corporation of Delta, started Traffic Calming measures several years ago. They installed Speed Humps along roadways and small Traffic Circles at various intersections. Although in theory and on paper these are effective, I believe they lead to other negatives.
Speed Humps are effective in slowing some traffic however, most drivers do not proceed effectively over them. If the speed limit on a roadway is 50km/h then there is no reason, or should be no reason, for a driver to brake to 30km/h or lower every time they approach and proceed over a Speed Hump. I can think of one stretch of roadway in the Corporation of Delta which is a 50km/h speed zone that has 5 Speed Humps and I've witnessed drivers break to 30km/h or lower for each Speed Hump. This creates other negatives such as increased potential for rear-end collisions, traffic delay, as well as aggressive driving by those behind the driver that feels it necessary to brake. The 2 main reasons for these negatives in my opinion are lack of driving skill or knowledge by the breaking driver and/or the Speed Humps are of inappropriate size requiring a vehicle to slow down to successful negotiate it without potential damage.
Traffic Circles vs. Roundabouts are they the same thing? In Europe for example primarily large multi-laned multi-directional structures are known as Roundabouts and I believe are effective in allowing many directions of traffic to enter and exit without the need for a Traffic Signal. In North America, and in the Corporation of Delta, they have taken the idea of Roundabouts and modified them to Traffic Circles replacing Stop Signs at Intersections. Most of these Traffic Circles are ineffective. They are too small to negotiate safely at a reasonable speed as it's impossible to see traffic approaching from most of the other 3 directions of travel due to the size of the circle, blocked lines of sight due to trees, houses and other objects; even the straight ahead direction is blocked by city beautician built right into the middle of the Traffic Circle preventing a driver from seeing oncoming traffic and/or pedestrians directly on the other side.
Overall, I believe Traffic Calming is necessary and essential in certain areas but in my opinion, many municipalities are not doing it effectively. The Traffic Calming measures many municipalities are currently putting into place might deter some traffic or slow down some drivers on a roadway but increase other negatives as a result. Municipalities should come up with effective Traffic Calming that have fewer negatives instead of putting in Traffic Calming just to be able to say they have it.
