Why not divert the end of Port Wakefield Road to just north of the Drive In's to meet up with Main North Road there? thus making the Gepps Cross intersection a regular 4 way..?claybro wrote:Re the Gepps Cross intersection and the varying points further Northeast. I believe that

Using x to mean + is a mistake - that's all there is to it. Of course this board isn't the first place people made that mistake and it won't be the last - but AFAIK it is the only place I know of where people, when informed of their error, still try to argue that it's not an error and 3x3 really does equal 6.
Using 3x3 to mean 3+3 is like claiming we should make the Dukes Highway safer by making it a duel carriageway!
You and Aidan do.[Shuz] wrote:Oh for the love of God, who cares.
Do you actually read through what you write, or have you realised you've dug yourself too far into your position that you must continue to defend it regardless of logic?I say 3x3, when I mean 3+3. At the end of the day, it's the same fucking thing

No for this intersection we would need our latest creation, the "double roundabout"rev wrote:A round about will fix it.

I have never been in favour of this option.rev wrote: Why not divert the end of Port Wakefield Road to just north of the Drive In's to meet up with Main North Road there?
I like the idea of this road being built, however I believe it shoud go straight over or under Main North Road, with only a slip lane from MNR (southbound) on to the new road (eastbound) and an exit from the new road (westbound) to MNR (northbound). The only reason for the new road would be for traffic to avoid Gepps Cross intersection (the "Grand Junction"?).[Shuz] wrote:

If I just may point out - the 'experts' always refer to it verbally as 'three by three'. If we're going to get 'technical', mathematically speaking, 'by' also means times, multiplied, etc. So in the verbal context, and I quote you, Aidan, "using x to mean + is a mistake". Oh, the horror! Won't someone please think of the children! #sarcasm
So on the one hand, verbally its said three 'by' three, when 'technically' they actually mean three 'and' three, or three 'plus' three. Same goes for the written translation. I say 3x3, when I mean 3+3. At the end of the day, it's the same fucking thing. I don't imagine that you are going to get into the habit of correcting every single person whenever they verbally say it 'three by three'.
Even if 3x3 was to be interpreted literally, how would that configuration even work? Three lanes one way, three lanes the other way, and three lanes... err... just because? I don't think such a configuration even exists. 2+2 and 2x2 both equal four, so there's no argument there to be had.
And in the one instance where 4x4 were to be interpreted literally (16 lanes in total) doesn't exist either. As far as I'm aware, the 401 Freeway in Toronto - which is the widest freeway in the world comes close (14 lanes total) as it consists of seven lanes, broken up into two segments going one way, three lanes, and the other four, and another seven lanes in two segments of three and four lanes in the other direction. (see pic below) To some, this would be 4+3+3+4, or to others, 7+7 or 7x7.
No. But nor does it mean you have 8 wheel drive.Hooligan wrote:If I buy a car that says it's a 4x4 on it does that mean I have 16 wheel drive?
