The necessity of a hard limit is most evident when we look at the physics of traffic safety. A pedestrian struck by a vehicle traveling at 30 km/h faces a 10% risk of death. Increase that speed to just 50 km/h, and the fatality risk skyrockets to 90%. This stark scientific reality is why city planners globally are aggressively lowering speed limits, especially in residential areas and busy pedestrian zones. The limit isn't an arbitrary number; it is a calculated safety threshold drawn from hard data that dictates survivability.
Budget limits are addressed through modular rubber pavements, recycled plastic curbs, and pop-up pedestrian plazas made from planters and temporary barriers. limitpedsasi
