In response to Samir Rawashdeh's plead: "People of the Internet, please help!" I decided to rub my head, and come up with something.

This is an idea which will reduce speed driving and save lives. This is how it goes:

Create a GPS enabled device which can be installed in any vehicle to monitor its speed. The device will be loaded with data about the city streets; Streets are given unique code numbers, which are then associated with the GPS coordinates of its entire path. On the road, special antennas will transmit the speed limit of every street in the city. The code for each street and its speed limit are then transmitted as Key-value pairs. This data can be compressed and transmitted repeatedly as a radio broadcast with a second pause between each transmission.

This data is then collected and processed by the device on the vehicle, and stored in a tiny database. Every few seconds, the new GPS location of the vehicle is matched with the corresponding street code number from the built in street database, the number is then matched with the speed limit obtained from the radio broadcast stream.

The device will keep monitor over the car's speed. If the car exceeds the speed limit of the current street, it will alarm the driver to slow down, and give him 10 seconds to bring his speed below the limit. If the driver does not comply , the device will send a signal to receivers setup at traffic control stations around the city, which will then relay that signal to a central police database where this incident will be recorded and a ticket issued for the driver. The device then tells the driver that a ticket has been issued. If the driver still does not comply, the device will keep updating the central police database with his current speed and GPS coordinates.

I hope this helps :)
