A system includes a processor configured to determine traffic density over a road segment. The processor is also configured to model traffic parameters to maximize traffic flow over the road segment, based on the traffic density and travel characteristic data received from a plurality of vehicles exiting the road segment. The processor is further configured to determine a speed to density curve, using the model, that would maximize traffic flow and send the speed to density curve to a vehicle entering the road segment.

A driving support system including an information acquiring part which acquires, from a vehicle side detecting a magnetic marker laid in a road and capable of acquiring marker identification information for identifying the magnetic marker detected, upload information including the marker identification information, an information providing part which provides the vehicle side as a transmission source of the upload information with support information, a configuration which provides information acquisition right which is a right to receive the support information to the vehicle, and a transmission source management area for registering the identification information of the vehicle as a provision destination of the support information by recording the identification information of the vehicle. The identification information of the vehicle is recorded in the transmission source management area and the information acquisition right is granted to the vehicle when the information acquiring part acquire the upload information.

A road information exchange system includes a plurality of Guided Autonomous Information Network (GAIN) units (102) installed on a road. Each GAIN unit (102) communicates with another GAIN unit (102) of the plurality of GAIN units (102) to divide the road into virtual lanes by formation of microgrids and further communicates with a vehicle passing through the road information exchange system (100).

A system and a method of detecting and handling traffic congestion outliers by at least one processor. Embodiments of the present invention may include: receiving, from a plurality of information sources, data corresponding to at least one temporal, local traffic property; producing a local, time-based traffic profile based on the received data; receiving, from at least one information source, new data corresponding to at least one temporal, local traffic property; analyzing the new data in relation to at least one respective time-based traffic profile, to produce a score of the new data; and if the score surpasses a threshold, then identifying the data as originating from a local, temporal traffic congestion outlier and producing at least one recommendation for handling the traffic congestion outlier.

A system for providing smart road infrastructure for the purpose of vehicle safety and autonomous driving, comprising a plurality of road units, which are located along the borders of each traffic lane and equally spaced from each other, where each road unit includes a read/write passive RF tag; antenna for communicating with a plurality of transceivers, each of which is installed on each vehicle that travels along a traffic lane of said road, in response to signals transmitted from said transceivers; a memory for temporarily storing data regarding each vehicle traveling along said lane. Each car unit comprises a reader for interrogating said tags. The reader includes a first transceiver that is installed on the left front of said vehicle and a second transceiver that is installed on the right front of said vehicle; a processor being in bidirectional data communication with said transceivers and with the vehicle inherent control systems, for processing data received from said tags and calculating speed and location of said vehicle with respect to the borders of said lane and to other neighboring vehicles traveling in said lane and adjacent lanes, to implement vehicle safety operations such as Lane Departure Warning, Forward Collision Warning, Lane Keeping Assist, Lane Centering, Side Collision Warning. Alerting the driver (visually and/or audibly) regarding potential problems and/or taking over control of the vehicle (ADAS 1-5). The system can provide Connected Vehicles with accurate (ubiquitous and instantaneous) location data with lane-level resolution. The proposed smart infrastructure may complement car sensors and/or connected vehicles, so as to implement a combination that yield the most relabel and cost-effective autonomous driving system.

In a marker detection method in which a sensor unit (11) that includes a plurality of magnetic sensors arranged in a vehicle width direction is used to detect magnetic markers (10) laid in a road, a feature value that represent symmetry of magnetic distribution, which is the distribution of magnetic measurement values obtained by each magnetic sensor included in the sensor unit (11) is generated, and threshold process regarding the feature value is executed to determine the possibility of the presence of magnetic generation source other than magnetic marker (10), that causes disturbance, and hence to suppress erroneous detection.
