traffic lights

Not Just Bikes explains how Dutch traffic lights use early detection, transit priority and conflict-free design to cut waiting. The aim is to move as many people as possible rather than as many cars.

Technology Connections explains how LED traffic lights, which do not melt snow, drew complaints and were blamed for accidents. He uses it to illustrate the 'but sometimes' fallacy against new technology.

CGP Grey explains how traffic jams come from human driving behavior such as tailgating and reaction delays, and how leaving gaps and smoothing speed would reduce congestion. It also touches on self-driving cars.

A short video from the trafficwaves.org site showing how traffic jams and standing waves form, including the fight between cheaters and blockers at an exit-lane backup. It also touches on how individual driving behavior affects the flow.

Oh The Urbanity! questions the framing that urban planning reforms like bike lanes and traffic calming wage war on suburbanites. It argues that suburban and urban residents alike want less traffic on their own streets.

CityNerd explains why traffic congestion grows nonlinearly as more cars use a road network, and why adding road capacity tends not to fix it. It covers the consequences for drivers, bus riders, cyclists and pedestrians, and discusses alternatives such as true bus rapid transit.

Technology Connections explains why American cars all had the same standardized sealed-beam headlights until 1957. It covers the regulations behind the design and the effect on night visibility.

JJRicks rides a driverless Waymo in Phoenix when it gets confused by traffic cones, blocks traffic, and evades the support vehicles sent to retrieve it. The episode is one of a long series of rider-view Waymo videos.

Not Just Bikes explains the Downs-Thomson paradox using Amsterdam and Toronto: road widening doesn't fix congestion, and buses stuck in traffic make transit slow. It argues for giving transit its own priority infrastructure.

Not Just Bikes shows how traffic calming is built into streets across the Netherlands, from city centres to villages. Street design naturally slows cars and makes roads safer.

Technology Connections experiments with filtering white and colored LEDs to make holiday lights look less garish. He explains why narrowband LED strings look harsh compared with incandescent bulbs.

Tom Scott investigates moire-effect beacons, called Inogon leading marks, a Swedish invention from the 1980s that shows different patterns depending on the viewer's position. He visits one used to mark an undersea cable and tracks down its history.

Not Just Bikes looks at traffic in the Bahamas to show that a small country can be just as car-centric as a big one. He ties it to land use, car dependence and how dedicated transit lanes help.

A three-minute student film from Campus MovieFest showing drivers in every lane holding exactly the speed limit on an Atlanta-area interstate and the traffic jam that results.

A short 2006 clip of chaotic traffic in India, with cars, bikes and pedestrians weaving around each other and one car going against the flow.

An art project by Simon Weckert in which 99 smartphones pulled in a handcart create a fake traffic jam on Google Maps. A green street shows as red, which diverts cars to other routes.

CityNerd Ray Delahanty explains induced demand and what happens when freeways are widened. He walks through the economics of supply and demand applied to traffic and asks how much new traffic appears and whether congestion returns.

Nine minutes of unedited footage of a very busy bicycle and car crossing at Korte Prinsengracht and Haarlemmerstraat in Amsterdam. Cyclists, pedestrians and cars flow through without traffic lights.

A short research demo of Autonomous Intersection Management, a protocol in which self-driving cars reserve slots through an intersection instead of obeying signals or stop signs. It uses UT Austin's autonomous vehicle Marvin and a simulation to show cars crossing without stopping.

A short clip of Meskel Square in Addis Ababa, a busy crossroads where vehicles and pedestrians mix with few apparent rules. Filmed in 2013.

Chuck Cook films Tesla FSD Beta 8.2 attempting unprotected left turns across forward-facing traffic, using a drone for a third-person view. Eight tests are shown with the car's on-screen visualizations.

Wendover Productions explains why Boeing's efficient 787 beat Airbus's giant A380, contrasting hub-and-spoke with point-to-point routes. It covers the economics of long-haul flights.

Not Just Bikes argues that stop signs are a poor traffic control, drawing on Dutch practice and the Idaho stop to show intersections can be safer without them, especially for cyclists.

Not Just Bikes explains why crossing streets is dangerous in the US and Canada, where roads are designed to move cars fast, and contrasts it with Dutch designs for pedestrians.

A 39-minute highlights reel of Bill Gates being deposed by David Boies in the 1998 to 2001 United States v. Microsoft antitrust case.

A WSJ report on China's 'dark factories', highly automated plants run by robots with little human presence, visiting Zeekr's EV factory. It covers Chinese labor costs, automation and overproduction in the EV industry.

Ted Young of LightStep proposes trace testing, using distributed tracing data to unify testing and observability. The KubeCon-era talk argues for testing against trace data rather than treating tests and monitoring separately.

A Waymo clip, sped up 3x, showing its autonomous car stopping at a broken traffic light and proceeding on a police officer's hand signals.

A KRAZAM comedy sketch in which Makro walks through the latest Microsoft Office 365 Excel update in a mock stream highlights format.

Not Just Bikes explains how North American speed limits are set and why posted limits matter far less than street design. It argues that drivers follow the road's cues, so safe speeds have to be built into the street.

A Last Week Tonight segment on pig butchering scams, in which long-con romance and investment fraud is run, often by trafficked workers. It explains how victims are groomed and interviews people who lost large sums.
