Traffic Preemption for Dummies
Thursday, February 28th, 2008You’re probably weirded out that a mobile gaming blog would be covering such an obscure topic. Well, at one point I believed that I could activate Traffic Preemption circuits simply by using the IR on my PSP. Sad but true. That thinking, however, wasn’t far from a real possibility. IR can be a medium of communication to trigger Traffic Preemption. It just seems absurd that a PSP could have such capabilities.
The Facts
- Traffic Preemption systems are activated by a 10-14hz flashing light
- Once the Preemption system is activated, it stops traffic in other directions safely and turns the user’s lights green
- Newer lights use a Encryption System so homebrewers can’t active Preemption
- This is illegal in most states and i do not condone its usage. I only know information
What is a hz?
1hz=60flashes per minute. Therefore, 1hz=1 flash per second. Theoretically, if you were to possess a strobe light, able to flash 10 times a second and bright enough to be detected, then the light should turn green.
Why 10-14hz?
The faster the flash, the higher the priority, the faster the light turns green. Police and EMS use different frequencies because they have different priorities.
Wouldn’t the encryption kinda kill the fun?
Yes it would. But, out of the hundreds of thousands of Traffic Signals in this country, only a very small hand-full use the encryption. Since the encryption is expensive, it’s doubtful that you’ll run into more than 1 in your preemption fantasies.
How can I get me one of those?
2 choices, either you
Buy One OR
Make One
Drawbacks of buying
Costs $300 dollars for a very simple rig.

In fact, behind the housing, This is all it is
Drawbacks of Building
Can you read schematics? I’m sort of in the dark about those things. The I-hacked page on how to build one is the closest thing you can get to building a pretty good one but it’s very difficult to follow. If you understand the bizarre nomenclature of electronics then be my guest, but i’d prefer something much more simple.
Vital Components
In the end, all you need is,
1) A power source
2) A controller device that can open and close a circuit 10-14 times in one second
3) An LED Array. The more LEDs the better!
Please Help ME!!
If you know of a controller device, something commonly found, please be so kind as to leave a comment
I would greatly appreciate it!
