A couple of years already, as for friends, they made a service on the knee to determine the location of the car and display it on the map.

Simple microprocessor (microchip), gps plug-in,
gprs to transmit information and a server on the Internet, which
obtains location information and displays
moving points on google map. A friend was responsible for working with a soldering iron, I did programming. I had to write on C for a microprocessor (a simple OS), on PERL for a server and a bit of HTML + JS and AJAX. With modern simplified technologies, this is all very simple. This I tell you as a bummer.

I don’t say exactly what my friend did with Palyanik, but they make beautiful
handkerchiefs that contain many small items and work great.
Already a couple of years, On the street. In any weather.

Think about it.
This was done by two people in their free time. Service is spinning now
several dozen machines, updated information once a minute. Everything is working
on the full machine.

At prices up to NG, it was worth less than 10k rubles to equip one car. Traffic
eats a penny.

Redo this system so that it displays trams online. Or sent
on request sms with the coordinates of trams. Or updated (via the same GPRS)
information on the scoreboard that we can create and hang out at stops.
It may take three or four months. And that's all.

Do you want trams, do you want trains? electric trains? yes don't care

So here. I do not even protrude in order to offer it to my native
city ​​(812). Because I understand - it is useless. Kickbacks - they rule. Communication - they rule.
Familiar programmers - dancers - they rule.

Every time when I once again see broken traffic lights, I cannot
understand that there may break? how can you invest SUCH money
something that is buggy?

Friends, I do not even understand myself what exactly I wanted to say :) maybe
be understand you.

ps
I will not give links :) I do not need PR.
