JOINT PROBABILISTIC MODELING AND INFERENCE OF INTERSECTION STRUCTURE

摘要

A method of modeling an intersection structure of a roadway. The method includes receiving a first data set including road lane information, and receiving a second data set including vehicle trajectory information for an intersection structure of a roadway. The method includes determining lane node locations from at least one of the first and second data sets. A set of potential links between the lane node locations may be compiled. The method may further include assessing, for each link, a probability that the link is a valid link, and assigning each link with a probability value. The links may be filtered based on a predetermined threshold probability value and a set of valid links is generated. A model of the intersection structure is created based on the set of valid links.

1. A method of modeling an intersection structure of a roadway, the method comprising:
receiving a first data set including road lane information; receiving a second data set including vehicle trajectory information for an intersection structure of a roadway; determining lane node locations from at least one of the first and second data sets; compiling a set of potential links between the lane node locations; assessing, for each link, a probability that the link is a valid link and assigning each link with a probability value; filtering the links based on a predetermined threshold probability value and generating a set of valid links; and creating a model of the intersection structure based on the set of valid links.
