A preformed thermoplastic roadway line marking includes a preformed thermoplastic substrate layer capable of being attached to a roadway, and a preformed thermoplastic upper layer in contact with the substrate layer. Advantageously, such an upper layer includes a surface area having a plurality of spaced-apart slits. The slits penetrate through an entire cross-sectional thickness of the upper layer and are in fluid communication with the substrate layer. When heated to a liquid state, the substrate layer has a morphed shape and is at least partially displaced upwardly through the slits and disposed on the upper layer such that the upper layer is fixedly locked to the substrate layer and maintained at a substantially stable position relative to the substrate layer. Such a structural configuration provides an unexpected and unpredictable result of insuring the marking is locked into place relative to the roadway, thereby reducing labor costs and improving durability.

There is disclosed a road sign plate comprising a base plate (2), a series of LEDs (4) arranged on said base plate and supply means associated to said series of LEDs in which, particularly, there is a first resin layer (1) laid on which covers, at least, the base plate (2) and a second resin layer (7) arranged over said first resin layer, wherein said second resin layer (7) is of a translucent material. This road sign plate is not expensive, features great capacity of mechanical strength and electric resistance and improved translucency properties.

A modular system of light strips is configured for use on a roadway surface. The light strips are configured to withstand vehicular traffic, such as passenger cars, trucks, and even heavy equipment such as found in a construction zone. The light strips have a rigid, durable housing that protects a series of LEDs within the housing. The LEDs are preferably positioned fully within the housing, with lenses directing light from the LEDs through the sidewall of the housing and toward vehicular traffic on the roadway. The channel is filled with a protective material, such as a polymer resin, for example a polyurethane resin, that serves to protect the LEDs and power supply running within the channel. The modular system can be provided with a power source, such as solar panels, or alternatively configured for connection to a power grid. The modular system can include one or more sensors to activate the system or alternatively to control the brightness of the lights in the system and be configured with light strips that connect together or can be substituted for one another allowing them to be interchangeable and easily carried, moved, installed and disassembled.

A system and method for providing increased traffic carrying capacity of a road, such as a highway, by modifying an existing roadway from, for example, four lanes to five lanes, to create an additional travel lane. The system and method dynamically changes the width of travel lanes using, for example, embedded pavement lights, or other lighting arrangements, in lieu of traditional painted lane lines. As traffic volumes increase and speeds decrease along the road, an intelligent transport system (ITS) sends a congestion signal to the overhead lane controls and dynamic message signs (DMS) along the entire road segment of interest. The posted speed limits are changed, and the lane markings are controlled to dynamically increase the number of lanes in the road segment to five, for example, of narrower widths until traffic volumes reduce and the number of lanes can be returned to four, for example, with normal speed limits.
