Roadways TRIZ Cases

Built-in protruding bends give a metal braided net added thickness for fuller mortar fill, higher strength, and no spacer blocks.

A looped header passage and ribbed stream straightener even out faucet pressure and distribution to produce controlled linear or grid flow.

Elevated ramps and a connecting deck separate heavy and light traffic, easing congestion where land and height clearance are limited.

Controlled pressed concavities filled and compacted with aggregate improve shallow ground stiffness uniformity and reduce settlement risk.

DC-driven silica and alumina electro-cementation turns weak calcareous sand into a rock-like structure with higher strength and lower CO2 impact.

Wind-driven cooling plates, insulation, and capillary barriers limit thaw settlement by controlling heat and moisture in permafrost subgrades.

Paired supports release upper sections by gravity, opening the roadway film tunnel for emergency access and ventilation.

Stepped slopes and layered geogrids stabilize in-situ highway embankment extensions while limiting excavation, land acquisition, and construction risk.

Parallel left and right-hand traffic lanes in a composite road module eliminate intersection conflicts, reducing congestion and improving flow efficiency.

A one-way loop mosaicking system enables vehicles to travel continuously without stopping at intersections.

An eight-way interchange uses a planar circular layout of forked roads to manage sixteen traffic directions without vertical stacking.

Low tunnels beneath a central platform enable split-flow for small and large vehicles, resolving traffic jams at busy intersections.

Shell elements slide laterally on gravity guides to extract smoke from enclosed routes, resolving fire safety constraints in tunnel structures.

Sliding precast units along guide tracks in access tunnels creates shallow transport routes, reducing surface disruption and land use.

An aerial multi-level bridge structure integrates a suspended monorail with vehicular roads and utility distribution networks.

Polymeric strips with staggered bonding form vented cells that maintain frictional interlock with fill materials under varying loads.

Repurposed wind turbine blade sections filled with coarse-grained material reduce weight and cost while maintaining strength for retaining walls.

Segmented elevated lanes isolate driverless cars from heterogeneous traffic, resolving the contradiction between automation levels and road safety.

An over and under cloverleaf interchange design routes vehicles through multi-level ramps to facilitate seamless transitions between intersecting highways.

Vegetated troughs on load-bearing structures create a semi-open covering that reduces noise propagation and improves urban air quality without tunnel costs.
