An information processing apparatus controls a road surface marking apparatus configured to form any road surface marking by changing light emission patterns of a plurality of light emitters provided on a road surface. In the information processing apparatus, a control unit detects, when switching from a second traffic lane through which a pedestrian is allowed to pass to a first traffic lane through which a pedestrian is prohibited from passing is executed, a user who is a pedestrian remaining in the first traffic lane after the switching. Then, the control unit causes the road surface marking apparatus to form an urging marking used for urging the user to withdraw from the first traffic lane after the switching.

A method includes positioning one or more roadway sensors and a plurality of a networked array of light emitting diode (LED) raised pavement markers on a road. Sensors proximate the road are associated with a network of road marking controllers that cooperate to control the LEDs as vehicles drive on the road. The LEDs operate as a networked array of roadway lane marking lights. The road marking controller(s) determine a distance between a vehicle on the road and the roadway sensor, determine a dynamic condition associated with the vehicle that changes with respect to time, and lights the plurality of LEDs based at least in part on the distance between the vehicle and the roadway sensor and the dynamic condition associated with the vehicle. Dynamic conditions for operating the LED lighting scheme can include vehicle velocity, a date, a time, a weather condition proximate the vehicle, and other factors.

The disclosed pavement marking system provides information about the arrangement of the pavement marking to a sensor on a vehicle for to identify a particular lane on a roadway. The pavement marking system comprises a sensor placed on a vehicle and at least a first pavement marking and a second pavement marking, wherein each of the first pavement marking a second pavement marking comprising different properties.

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.

A system of active lane markers in a roadway, the active lane markers comprising sensors, transmitters and receivers to monitor the status of the roads and provide vehicle guidance to vehicles in response to analysis of sensor data.

A modular system of light strips is configured for use on a roadway surface. The light strips are configured to withstand vehicular traffic driving over the light strips. The light strips have a rigid, durable housing protecting a series of LEDs within the housing. LED lenses direct light from the LEDs through the sidewall of the housing at vehicular traffic on the roadway. The channel is filled with a protective material, such as a polymer resin that protects the LEDs and power supply. The modular system includes a power source or can connect to a power grid. The modular system can include a sensor to activate the system and/or to control the light brightness Preferably the light strips connect together or can be substituted for one another to be interchangeable and easily carried, moved, installed and disassembled.
