I am a UK Traffic Signals Engineer. The nearest thing you can have is a Bus Beacon, so the traffic signals see think you are a Bus and try to give you priority (a green signal) as soon as possible,
The bus beacons are becoming more sophisticated , so you have to know what Bus route number to emulate and how to emulate a empty Bus.
Even when you know the MIB its not practical, by the times you have reconfigured your Bus Beacon it will be a green signal anyway.
Traffic Signals (Lights) use non-standard analogue frequencies and protocols which are not published.
The protocols are a pig even when you know them, no easy task for a script-kiddie
One of the basic functions of a traffic signal controller, why they cost so much, is that they will not allow an un-safe condition to appear on the street, e.g. Green-Green conflict. Even hardware-mods can not force a green-green conflict. Unless you can blow a PROM, in the correct (un-published) format
Traffic lights take very little bandwidth to operate, generally they are on a 200 KHz system that works like the X-10 switches many people have in their homes.
UK Traffic Signals (lights) run at 200 b/s, or even 1200 b/s in the UK. (Yes b/s not Kb/s) We are just getting rid of the 50 baud equipment, (Shame).
Basically one _bit_ determines which sets of lights to go green (a phase) so the bandwidth is minimum. In the UK, an analogue leased line is used to send the information to the set traffic signals (lights). Which is just a little better than wet string to send data on, but it works.
Before you think of hacking (this is/.), the on-street traffic controller will not allow set of conflicting green signals to go on at the same time. But in theory you could get out of you car connect an analogue modem, copy the bit pattern, then set the correct bit to give you a green signal, but the modem operating frequencies are non-standard...
We are now trying to run traffic lights at 19,200 (wow),cutting edge. Just to give us background non-control channels.
Anyway we are just undertaking a study in to different of new ways to communicate to traffic lights. So I will try to get some info from Hydro-Quebec - to see if there is any thing I can plagiarize.

Sun's Java is a Morphix based CD.
Most knooppix/morphix/other can do this using boot option:
:
toram
E.g. Morphix from prompt boot
morphix toram
Allowing you do everything yo/u would, incluyding burning cd, playing DVD.
Alex Treme does all the hard Work on Morphix but, I am trying to keep the Morphix FAQ upto date and have also written a HowTo with the aim of being really easy to follow.
So any constructive critisism would be helpful, either here or on the Morhphix Forum
Thanks,
Brendan
In the UK you can not get remote control of traffic signsls.
I shall avoid starting a flame war on UK vs. USA traffic signal engineering ;-)
Hey like an early response said the world is not jsut USA/UK/Europe.
They do not exist, it not technically possible.

Cool Britannia ?
Yes, right, now back to earth. Looks like we did not even test the radio link.
Sigh
Hummm what a good idea.
Please do not all call Mr Charles Fish at once we do not want him being /.ed. One at a time please ....

Try Knoppix for PPC (MIB)
I also gave 192.com a unique email address, no spam on this yet. 6 months +

Any more detail of the Femto XTX, Url?
Thanks,

Oaster card are used for Buses as well (all part of TfL) (I have an oaster card already as I am a TfL employee)
But I prefer morphix BMS
