Abstract: A system, method and server for a controlling a relation between a vehicle and traffic flow over a road segment. The system includes a telemetric device of the vehicle and a processor of the server. The telemetric device obtains telemetric data related to the road segment being traversed by the vehicle. The processor determines a property of the road segment based on the telemetric data and a road profile for the road segment, determines a disruption score indicative of a level of disruption in the traffic flow for the road segment based on the property, and outputs a notification signal when the disruption score is above a selected disruption threshold. The notification signal is usable for controlling the relation between the vehicle and the traffic flow.

Abstract: A system for quantitively determining quality for pavement markings disposed along pavement on a roadway includes one or more controllers in wireless communication with a plurality of vehicles. The one or more controllers receive image data represents the pavement markings disposed along the pavement collected by the plurality of vehicles. The one or more controllers execute instructions to determine at least one of a color distance measurement between a mean color space value of the pavement markings and an ideal marking color space value and a marking intensity contrast ratio between the pavement markings and the pavement.

Abstract: A weather sensing and reporting system includes a filter module configured to receive weather condition data collected by a plurality of vehicles in a reporting region and filter the weather condition data by selectively removing individual samples from the weather condition data based on meteorological quality control standards. A weather condition calculation module is configured to calculate weather conditions in the reporting region based on the filtered weather condition data and a report generation module is configured to generate and transmit a weather report based on the calculated weather conditions.

Abstract: A method for facilitating uses of a code for vehicle experiences includes receiving code data from the code in a sign. The sign is disposed outside a host vehicle. The method further includes establishing a connection with a service using the code data obtained from the code and in response to establishing the connection with the service, receiving service data. The service data includes information about the service. The method further includes, in response to receiving the service data, controlling the host vehicle according to the service data received after establishing the connection with the service.

Abstract: A method to identify lane-level road congestion includes: modeling a lane-level congestion evolution process as a 2-dimensional (2D) Markov chain having multiple vehicles moving through a predetermined segment of a road; aggregating a volume of the multiple vehicles over a predetermined unit of time moving through the predetermined segment of a road; populating a lane congestion map identifying individual road lanes having differing levels of congestion; directing an output of the lane congestion map and an output of a lane congestion model to a lane routing engine; and identifying routes and route changes for a host vehicle to apply to improve a host vehicle estimated time of arrival (ETA) at a predetermined finish location.

Abstract: A method to incorporate lane level road congestion to enhance vehicle navigation includes: collecting vehicle data from a fleet of vehicles; identifying a lane level distribution of multiple vehicles operating on a road having multiple lanes including a host vehicle; comparing the lane level distribution against a non-congested lane of the road; and identifying if a lane level congestion is occurring in at least one of the multiple lanes.
