Fighting crime with math: Model explains hot spots of illegal activity

Using a decade of data from the Los Angeles Police Department, UC Irvine criminologist George Tita and colleagues developed a mathematical model of how urban crime hot spots form and spread. It reveals two distinct types of areas that respond differently to suppression tactics.

Illegal activity follows a discernible pattern, Tita says: “Criminals forage for opportunities to commit crimes, much like bees search for pollen or butterflies for nectar. Foraging patterns are predictable, whether you study human or insect behavior.”

Take That, DuPont Circle

Vortex Junction: The Next-Gen Roundabout

Roundabouts work great in low traffic volume areas because the number of vehicles in the intersection at one time is low. They eliminate traffic stops like signs or lights and allow traffic to move smoothly. When they’re installed in high traffic areas, roundabouts can become a nightmare. The trouble with roundabouts, especially big ones, is drivers are always jockeying for position along the outside lane since there are always vehicles entering into, in the intersection and attempting to exit along the outer diameter. This is a problem the Vortex Junction solves.

I don’t know if this is the answer, but it’s an interesting idea.

Traffic circles in and around DC, especially DuPont, should have been mentioned in Dante’s Inferno. High volume, poor signage, modifications that render them even more problematic (through lanes on the diameter and traffic lights) and inconsistent right-of-way protocols (some places people in the circle have the right-of-way, for others it’s those entering the circle. WTF?)

I avoid DuPont circle like it’s made of toxic broccoli.

from Mar 21:

In my mind, this was not a walk, but a hike.
A hike so “treacherous” I let someone else carry the camera.
Regardless, this type of exercise totally beats a treadmill with cable news.

I was reminded of this just this past weekend. The weather was awesome, and I went out geocaching (up in Mary-Land). Even though I’d gotten back on the treadmill after being sick in January (the aftereffects of which spilled over into February), walking a few miles up an incline on a treadmill doesn’t really match up with doing the same over the uneven terrain of a park trail.
