A method, system, apparatus, and computer program products provides the ability to dynamically define and generate inlet spacing along a road in a building information model (BIM) computer aided design (CAD) three dimensional (3D) model. A representation of a road is acquired in the BIM CAD 3D model, wherein the representation includes a geometry. An inlet spacing is defined for the road. Inlet locations for inlets are determined based on the inlet spacing. A determination is made regarding whether the inlet spacing and inlets satisfy design rules for the road. When the inlet spacing and/or inlets fail to satisfy the design rules, a different inlet spacing is selected from a group of preset integers, and the process repeats until the design rules are satisfied.

A system for extracting polluted air in the vicinity of a road surface, the system comprising at least one inlet assembly arranged to be recessed into the road surface and to be connected to an extraction duct, said at least one inlet assembly comprising: a pod arranged to protrude above the level of the road surface and to be driven over; and one or more intakes located within the pod, the pod defining a passage arranged to be connected to an extraction duct.

An energy harvesting roadway that includes a plurality of road segments and a power storage device electrically coupled to the plurality of road segments. Each of the plurality of road segments can include a surface asphalt layer, a first conductive asphalt layer located under the surface asphalt layer, a piezoelectric-based asphalt layer located between the first conductive layer and a second conductive layer located above a base asphalt layer. The piezoelectric-based asphalt layer can include a plurality of rigid piezoelectric elements and an insulating filler.

The invention relates to an automatic transport system based on a network of one-way high-speed-traffic lanes (25, 26, 27, 28) without crossings or red lights, mainly on a pylon (13), dedicated to vehicles capable of operating in an automatic mode in which the driver plays no part in controlling the automotive vehicle. The transport system has stations for the travelers which are different from the entry and exit zones for the vehicles and has high-speed-traffic lanes and service lanes, so that not all of the vehicles are forced to go past the stations and the entry and exit zones.

A roadway system of sinusoidal one-way roads which surround individual developed areas. A straight bidirectional road intersect the sinusoidal roadways at locations in which the sinusoidal roadways are substantially tangent to one another and orthogonal to the bidirectional road.

An elevated roadway for autonomous vehicles may include a pylon extending vertically from a ground anchor and comprising a metal tube defining a central cavity and a concrete column within the central cavity. The elevated roadway further includes a bracket coupled to the pylon and comprising a mounting plate secured to the pylon and a cantilevered road support member extending from the mounting plate. The elevated roadway may further include a cantilevered road section coupled to the pylon via the cantilevered road support member and comprising a joist structure structurally coupled to the cantilevered road support member, a road member above the joist structure and supported by the joist structure, and first and second side barriers along first and second sides of the road member, respectively. The road member may be adapted to receive a four-wheeled roadway vehicle.
