tweebaans

Tweebaans is a term used in speculative urbanism and world-building to describe a dual-lane street system paired with a corresponding social framework. In this fictional concept, cities arrange two parallel roadways along major corridors: a primary vehicular lane and a secondary mixed-use lane that prioritizes pedestrians, cyclists, and local commerce. The two lanes run in close proximity and are interconnected by frequent cross-access points, with signaling designed to coordinate all modes.

Etymology and scope: The name is presented in various sources as derived from a constructed language influenced by Dutch, with twee meaning two and baan meaning track or lane. In different settings, tweebaans can refer either to the physical street layout or to the social arrangements that accompany it, such as shared governance or collaborative use rights.

Design and features: Typical tweebaans layouts include a raised central or side median, protected bike lanes, pedestrian refuges, and signal timing that gives priority to non-motorized traffic at many intersections. Urban plans drawn in tweebaans contexts emphasize multi-modality, safety, and streets as public spaces rather than conduits for vehicles.

Reception and usage: In the fan and professional discourse surrounding speculative urbanism, tweebaans is used to explore contrasts with car-dominant planning and to imagine inclusive, walkable cities. Critics note that implementing such layouts would require careful cost-benefit analysis, coordination across agencies, and adaptation to local cultural norms.
