Making an intersection unsafe for pedestrians to save seconds for drivers

Original Article ↗ Hacker News Discussion ↗

Dutch / international design standards

  • Many argue the safety problem is “solved” by Dutch-style road design: slow, visually constrained streets; tight turn radii; traffic calming; and full separation of bike and car networks.
  • Others ask how applicable these standards are in areas with little current bike traffic; reply is that bike traffic appears where safe bike infrastructure exists.
  • Links to Dutch guidance (SWOV, CROW) are shared; commenters note it’s essentially book-length, not a single trick.

Traffic lights vs 4‑way stops at this intersection

  • Some pedestrians prefer signals with an all‑way “scramble,” claiming it’s safer than a busy 4‑way stop where drivers are distracted by other cars.
  • Others say 4‑way stops are safer for pedestrians because speeds are lower and everyone must stop, reducing impact severity.
  • Debate over whether switching this specific intersection to a signal made it safer or merely faster for cars and worse for people on foot.

Yellow/red light behavior and legality

  • Long subthread on whether the cars in the video “ran a red.”
    • Some insist they entered legally on yellow and were still in the intersection when it turned red.
    • Others say they clearly had time to stop and accelerated through, which is dangerous even if technically legal.
  • Laws differ by jurisdiction on entering on yellow and clearing on red; commenters note this ambiguity itself is a safety issue.

Roundabouts

  • Several propose a compact roundabout as safer and higher‑throughput.
  • Others counter that roundabouts (especially multi‑lane) are hostile to pedestrians and cyclists, and often confusing in North American practice.
  • Suggested mitigations: raised crosswalks, pedestrian signals at roundabout entries, speed humps, and set‑back crossings.

Pedestrian priority, “beg buttons,” and mid‑block crossings

  • Strong dislike of “beg buttons” that delay walk signals or only trigger after a full vehicle phase; people often cross anyway, then the light changes pointlessly.
  • Some want signals to idle in an all‑red or pedestrian‑green state, forcing cars to request green.
  • Support for mid‑block crosswalks where people already jaywalk; others report drivers often ignore unsignalized mid‑block crossings.

Car culture, politics, and enforcement

  • Many see the redesign as another example of car‑first priorities and “safety theater” that preserves speed.
  • Others emphasize that saving “seconds” per vehicle aggregates to important time savings and economic benefits.
  • Disagreement over using cameras: some push automated enforcement; others raise privacy, surveillance, and data‑sale concerns.
  • Several note local political resistance to any change that slows drivers, and low, biased police enforcement of traffic laws.

Cost and implementation

  • $600k for one signalized intersection is widely viewed as high; explanations include expensive hardware, engineering studies, labor (incl. union/prevailing wage), and ancillary work (pavement cuts, curbs, markings).
  • Some suspect “boondoggle” dynamics; others argue that good design and safety are worth the cost.
