path planning

Walt Disney Animation Studios' short introduction to path tracing, showing how rays are traced and bounced through a virtual scene to simulate light. It explains how this approach is used in animated films.

A short BicycleDutch video on how the Netherlands got its cycling infrastructure, including the 1970s protests and the shift away from car-centric planning. The channel later published an updated version.

The first episode of a Cities: Skylines series on urban politics and planning, focused on parking. It uses the game to show how parking minimums shape cities, drawing on Donald Shoup's book The High Cost of Free Parking.

Not Just Bikes contrasts traditional and suburban development in North America. It looks at the financials behind each pattern and argues that suburban development leaves cities unable to pay for their own infrastructure.

Not Just Bikes explains that car-dependent suburbs are not the only option, using Toronto's Riverdale as an example of a pre-war streetcar suburb. These walkable neighborhoods are popular but are now effectively illegal to build.

Not Just Bikes argues that the Netherlands, famed for cycling, is also the best country for drivers. It explains how prioritizing walking, cycling and transit makes driving faster and more pleasant.

Not Just Bikes argues that car-dependent suburbs rob children of independence, contrasting North American suburbia with Dutch cities where kids walk and bike on their own. It is the creator's remake of an earlier video on the topic.

Not Just Bikes explains, using Urban3's property-tax analysis, why car-dependent suburbs generate less tax revenue than they cost to maintain, so dense urban cores effectively subsidize them. It is part of a Strong Towns series.

The School of Life sets out principles for making attractive cities, arguing that the art has been lost in the modern world.

Not Just Bikes looks at the tiny microcars such as the Canta seen around Amsterdam. It discusses how they serve people with mobility issues, can use bike paths under certain rules, and where they fit in a 21st century city.

A Two Minute Papers episode on NVIDIA's recurrent denoising autoencoder, which cleans up noisy Monte Carlo path-traced image sequences. It shows how a neural network can produce usable renders from very few samples.

Strong Towns explains the Growth Ponzi Scheme, in which post-war suburban growth takes on infrastructure costs that new development must keep funding. It describes why municipal finances become insolvent.

Tom Scott visits Peachtree City, Georgia, which has about a hundred miles of dedicated golf cart paths that serve as an alternative to driving. He explains how the network works as a quasi-transit system that keeps cars off the roads.

Not Just Bikes visits Paris to see how Mayor Anne Hidalgo's policies are turning it into a '100% cyclable' city. It looks at the changes that took space from cars for bikes and people.

Not Just Bikes introduces the "stroad", a street-road hybrid common in the US and Canada that fails at both jobs. He contrasts it with Dutch design, where each road has a single purpose, and covers cost, danger and ugliness.

Not Just Bikes explains the Strong Towns argument that car-dependent American suburbs cost more to maintain than they generate in taxes. It describes the growth Ponzi scheme that props up municipal finances.

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.

Not Just Bikes argues that winter is not what stops Canadians cycling, using Oulu, Finland as proof that safe, well-maintained cycling infrastructure enables year-round biking despite harsh weather.

Not Just Bikes argues that urban noise comes mostly from motor vehicles, drawing on the book Curbing Traffic and a visit to Delft, a city that takes noise seriously.

A video explaining why Japanese cities look the way they do, through Japan's national tiered zoning system that permits mixed use and flexible development. It compares this approach with more restrictive zoning elsewhere.

The first video in Not Just Bikes' Strong Towns series explains the financial instability of North American cities, based on Strong Towns research. It argues that low-density suburban growth costs more to maintain than it brings in.

Not Just Bikes explains how many American suburbs, built all at once rather than incrementally, cannot cover their infrastructure costs and survive on growing debt. It draws on Strong Towns' work on the growth Ponzi scheme.

Not Just Bikes explains how small pockets of shops and restaurants inside residential Dutch neighbourhoods create liveliness and help reduce traffic. It argues this kind of mixed-use design has been illegal in most of the US and Canada for a century because of zoning, and should be brought back.

Not Just Bikes explains missing middle housing, such as duplexes, townhouses and small apartment buildings. The video argues that zoning in the US and Canada has made these options almost illegal.

Not Just Bikes argues that people in walkable, bikeable Dutch cities stay healthy because exercise is built into daily life, which he calls the gym of life. It contrasts this with car-dependent cities that require deliberate workouts.

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.

A short BicycleDutch episode showing how people with disabilities use Dutch cycle tracks on hand-cycles, tricycles and mobility scooters.

Not Just Bikes takes on the common excuse that a country is simply too big or spread out for good transit and walkable cities. The video argues that city density and short everyday trips matter, not national size or overall population density.

Not Just Bikes explains why cars rarely crash into buildings in the Netherlands, attributing it to street design that forgives mistakes and to systematic crash investigation. It contrasts this with North American acceptance of such crashes.

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.

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.

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.

Not Just Bikes explains the Dutch concept of autoluw, or nearly car-free, streets and how it is applied across the Netherlands, with examples from Toronto and Copenhagen. It also covers Amsterdam's move toward a nearly car-free city.

Not Just Bikes contrasts typical car-dependent North American business parks with one near the airport in the Netherlands that works for driving, cycling and transit. It looks at how the design makes commuting easier.

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.

Not Just Bikes explains how an electric bakfiets (Dutch cargo bike) replaced the family car after a move back to Canada, saving thousands of dollars. It shows how much it can carry, including kids and groceries.

Not Just Bikes explains why upright Dutch-style bicycles are comfortable and practical, and why they are rare outside the Netherlands.

A Vox explainer from the 2020 election series on why American public transit is so poor. It traces the effect of the interstate highway system on cities and the resulting car dependence.

City Beautiful explains how Houston, which has no formal zoning, still shapes land use through deed restrictions, parking minimums and buffering ordinances.

Not Just Bikes explains why living in a dense, bikeable Dutch city sharply reduced his family's environmental footprint and improved quality of life. It is a collaboration that continues on Climate Town.
