At one point, Los Angeles had over 100 cameras to catch red-light runners. Then the city tore ’em all out. Here’s why.

Some stop lights are broken. Even if every corner had a red-light camera, many people would still run red lights. Here are the three toolkits engineers use to reduce or eliminate red-light running— often without a camera!
Red-light cameras seem to magically know when a driver runs a red light. Here’s how engineers build real technology to take pictures of cars that don’t stop.
Middle-of-the-block crosswalks are terrible. Most do not qualify for a stop light. I meet the inventor of the Pedestrian Hybrid (HAWK) beacon, a traffic device that fixes America’s forgotten crosswalks.
Raised medians reduce left turns which prevents crashes (and saves lives). But cities only block left turns for some businesses and not others. How can the engineers decide fairly? And what do we do with drivers who still need to turn left? ——————————- Additional reading: ——————————- Federal Highway Administration. https://safety.fhwa.dot.gov/saferjourney1/library/countermeasures/16.htm.

Traffic travels in both directions. So it makes sense we’d have a malicious moniker for two-way left turn lanes (TWLTLs). Are they actually dangerous, though? Let’s look at the safety of these middle lanes. After all, they are on roads pretty much everywhere in the United States. ————– Sources cited: ————– Mukherjee, D. Choosing Between […]
