Abstract: A method, system and computer program product for automated detection of map road segments requiring speed limit correction is disclosed. The method includes receiving a request from a quality estimation scheduler; initiating a computer program that automatically: receives a set of map road segments for a given region; receives a speed traffic report for the map road segments during a predefined time interval; identifies a subset of the map road segments that satisfy a predefined traffic speed criteria; further reduces the subset of the map road segments by corroborating with complementary speed limit signs information; compiles a list of map road segments requiring speed limit correction; comparing traffic speeds of the reduced subset with corresponding speed limit signs reported by a map database; and updating map speed limits where required based on the compared traffic speeds.

Abstract: A method, system and computer program product for probe provider attribution are disclosed. The method includes receiving from speed probe sensors, for a given region and within a predefined time window, speed probe data from a plurality of corresponding probe providers reporting both consumer vehicle speed probe data and truck speed probe data; combining the speed probe data from the plurality of corresponding probe providers into a single speed probe set; identifying an optimal number of speed clusters for the combined speed probe set; mapping each of the speed probe data from a plurality of corresponding probe providers to one of the optimal number of speed clusters and calculate a distribution of probe provider probes among the speed clusters; and assigning an attribute to each of the plurality of corresponding probe providers based on the distribution of probe provider probes and according to predefined criterion.

Abstract: The disclosure provides a system, and a method for quality estimation of a traffic congestion incident reported by traffic system based on the information from one or more probe vehicles. The system is configured to identify one or more road segments and location information associated with the traffic congestion incident reported by traffic system based on the information from the one or more probe vehicles. A probe-based space-time diagram is generated based on the identified one or more road segments and location information associated with the traffic congestion incident reported by traffic system based on the information from the one or more probe vehicles. Ground truth is inferred for the traffic congestion incident. The generated probe-based space-time diagram is compared with the inferred ground truth for quality estimation of the traffic congestion incident reported by traffic system based on the information from the one or more probe vehicles.
