It's pretty easy to hack traffic lights

Yeah, it all depends on your local gov. Beverly Hills times their lights to get people out of BH as quickly as possible, and onto someone else’s streets.

They temporarily altered it to cooperative timings after the Northridge Quake broke the Santa Monica Freeway, but then reverted to their old “jam up someone else’s streets” strategy once the broken freeway was fixed.

Burbank has always tried to be a verrrrra high-tech city, and I expect their signals run on their extensive municipal fiber-optic network, but their timings are nowhere NEAR as good as LA’s ATSAC. You can tell when you cross the border by how many red lights you hit.

I can roll halfway across the San Fernando Valley in LA without hitting a red light if I just relax and “go with the flow.”

The people stopped at the red lights are mostly the halfwits and testosterone cases who think they’ll get somewhere faster if they drive like maniacs to get to the next light while it’s still red.

But Burbank… <sigh>

Serious traffic-light hackers just install “skimmer lights” in front of the real ones.

The networking protocol is proprietary and unencrypted, and uses non-modifiable default passwords that are published online by the systems’ vendors. By default these systems have the debugging port turned on,

If a student brought me this as homework I’d see if I can retroactively make them fail earlier courses.

This would have been my question.

While debug access in the default configuration and hard-coded passwords are a big vendor fuck-up this is not an end-of-the-world-as-we-know-it finding. Sure, it can make city traffic more SNAFU, but would anyone notice this in e.g. rush-hour congestion?
