I'm having a really hard time seeing how this is any different than a traffic light being out. If "me-go-you-go" fails, why don't they just have a traffic officer out there directing traffic manually?
Any idea what type of systems they are running?

There are reports in the local press of these kinds of problems: "CityLink says it closed the tunnels because the IT problem affected incident detection and safety systems that are activated in the case of an accident. The network problem also affected the back-up system." ~ http://www.heraldsun.com.au/news/breaking-news/melbourne-tun...
And references are being made about inability to communicate to remote devices via the network, "lost the ability to communicate" with its incident detection and safety systems." ~ http://www.itnews.com.au/News/317694,citylink-glitch-shuts-m...
See, this is why we need to hurry up and deploy networked computerized automobiles. We won't need stoplights anymore, so this kind of stuff won't happen!

The ABC has an article with a quote that explains it better ( http://www.abc.net.au/news/2012-10-03/tunnel-closures-cause-... ): CityLink spokeswoman Kate Murphy says the tunnels had to close as a precaution. "It's not just overhead signs [that are not working], it's also our safety systems as well," she said. "For example, in the tunnels the deluge systems or the smoke extraction systems which we may use in an emerg…

The fact that their safety systems (Which anyone would expect to be separate from the traffic control systems) are also affected makes me wonder about the "computer glitch" angle.
As much as I don't want to sound like a conspiracy person, that level of connection between those components is a bit too much to believe. Especially in Australia where they have insanely high standards for construction/electrical engineering.

We will still need safety systems in tunnels though, and lack of those is why they shut the tunnels down. Ignore the misleading quotes about the variable limit signs not working, the real issue is the tunnel is not safe if there is a problem like a fire of fume buildup.
If mankind can't get a tunnels systems to work all the time, then what about our plans to introduce computer controlled cars? A glitch could wipe out millions of lives before being patched, and even then if they get patched that also introduces huge areas of vulnerability.
I'm sure a stealth program that loads onto a car and waits till a date to kill the occupants will be used by someone or a nation-state in the future.

It's more like 20km of traffic lights being out. These roads are our core east-west arterial roads and the landscape dictates that there aren't many other roads for the traffic to travel on. I can't say why there aren't traffic police out there, but these are once-public roads that have been privatised. Also, these roads are highways, not traffic intersections. Point of trivia: before the current toll road company wa…
The tunnels never were public roads, they didn't exist. You can still drive on pretty much the entire length of the West Gate Freeway, right up to the tunnel portals without paying tolls. There are some short sections of motorway though that were previously un-tolled but are now tolled, though there has been some pretty extensive upgrades.
That said I'm no way in favour of City Link, but the real core 'arterial' for urban commuting is our public transport system. :-)

I think he was being sarcastic, hinting that network computerized auto-mobile's having a similar glitch would be truly devastating.
