MIT Algorithm Predicts Red Light Runners
adeelarshad82 writes "Researchers at MIT have developed an algorithm that determines which drivers will run a red light, within one to two seconds before a potential collision. The research, based on 15,000 cars at a busy intersection, monitored various factors to determine which cars were were likely to run a red light. They found that their predictions were correct about 85 percent of the time, which is about 15-20 percent better than existing traffic prediction algorithms."
Nah. That'd cause a car to stop dead in the middle of the intersection and make a bloody mess of traffic.
Instead, you want a smart deployment of spikes which puncture only a single tire. More than enough to seriously piss off a guy running the light, while still letting him limp out of the way to the shoulder.
...As for the 15% error, did anyone consider cargo?...
THANK YOU!!! As an economic refugee of the "Great Recession", I ended up driving a tractor-trailer for a living - and wound up learning a few things along the way. One interesting fact I've learned is that a fully loaded (80,000 lbs) semi moving at 55 mph can take up to 300 ft to come to a complete stop (think about that next time you want to "brake-check" a truck...). I have, unfortunately, run across traffic lights in which the yellow phase was, for some strange reason, really short- even if the the semi is traveling the legal speed limit. This is not a situation you want to be in: your choices often boil down to:
(1) Stand on the brake in order to not run the impending red light (remember that 300-foot stopping distance? By the time you get stopped, your trailer in squarely in the middle of the intersection. And that's if you don't jackknife and end up wiping out 5 or 6 cars along the way).
(2) Run the light (Yes, it's going to be red by the time you hit it, meaning you will almost certainly incur the wrath of any red-light camera or nearby cop - but see option 1 for the alternative scenario)
This is probably the number two reason I try to avoid surface streets when possible (reason number one being the preponderance of infrastructure not exactly designed with a 75-ft long, nearly 14-ft high vehicle in mind). I figure any traffic engineer worth his salt is going to take these factors into consideration; a failure to do so is going to inevitably invite the occurance of an 18-wheeled clusterfuck and all that comes with it (major property damage, potential loss of life, etc).
This space for rent!
That's a pretty big assumption. The advantage this thing has is that you can outfit the traffic lights to delay the green light while the runner crosses and prevent the problem without instrumenting every car on the road.
And ticket the jackass who might have killed someone.

The person tailgating you is likely going faster than you. So why do you feel it's your right/duty to block them? You are not the enforcer of laws. Get out of the way, let them go by, or whatever. It's not your job to police people. Lead, follow, or get out of the way.
