I read an interesting "Letter to the Editor" in the April 7th Standard about Stop the Stop Signs. The writer obviously knew what he was talking about as he was an Energy Conservation Committee Member.
I have lived in Canada most of my life but was brought up in the U.K. where they often have "Yield" signs instead of "Stop" signs. The road that I grew up on was a quiet street but crossed by a very busy highway, in fact the famous annual London to Brighton rally for old classic cars still travels this main road.
Obviously there are no four way stop signs and the only sign that makes you check the busy road is a Yield sign. If there is traffic approaching you must yield or stop until the way is clear. If there is no traffic you just need to slow down as you enter or cross the main road.
The other common sight on U.K. roads of course are round-a-bout's or traffic circles. They can be just a few meters in diameter or built to control traffic on major highways. We see more and more on Canadian roads, one in mind was recently built at the intersection of Concession road 9 & the York Durham Town Line replacing a stop sign. This intersection previously created many accidents due to poor sight lines.
Negatives would be the cost to build and, a lack of available land, especially in existing or new sub-divisions. A new stop sign can be put up on any corner in just an hour or so, not so traffic circles which would need to be designed during the planning process in order to create space. However, yield signs would work where a stop sign is currently called for or even to replace unnecessary stop signs at intersections where traffic is clearly visible. Just my opinion anyway
