    Abstract: Predicting future infrastructure performance of a pathway article based on data for infrastructure performance features that influence predicted infrastructure performance at a future point in time. To predict infrastructure performance at a future point in time, a computing device receives one or more sets of infrastructure performance data for a pathway article that correspond respectively to infrastructure performance features. The infrastructure performance features may influence predicted infrastructure performance of the pathway article at a future point in time and the infrastructure performance data may correspond to a roadway portion. The computing device may generate, based at least in part on applying the one or more sets of infrastructure performance data to a model, at least one infrastructure performance prediction value that indicates predicted infrastructure performance of the pathway article at the future point in time.

    Abstract: In some examples, a computing device includes one or more computer processors, a communication device, and a memory comprising instructions that cause the one or more computer processors to: receive, using the communication device and from a set of vehicles, different sets of infrastructure data for a particular infrastructure article that is proximate to each respective vehicle of the set of vehicles, wherein each respective vehicle in the set of vehicles comprises at least one infrastructure sensor that generates infrastructure data descriptive of infrastructure articles that are proximate to the respective vehicle; determine, based at least in part on the different sets of infrastructure data for the particular infrastructure article from each respective vehicle of the set of vehicles, a quality metric for the infrastructure article; and perform at least one operation based at least in part on the quality metric for the infrastructure article.

    IPC: G02B5/124

    CPC classification number: G02B5/124

    Abstract: Cube corner articles such as retroreflective sheeting utilize multiple cube corner arrays in a tiled configuration, each tile containing one array of canted cube corner elements. The tiles may be long and narrow, and the array in each of at least two or three adjacent tiles, or even in every tile, may include at least one lengthwise groove that is parallel to an edge of the tile and parallel to a fixed in-plane axis. Each tile may have a width that is narrow (e.g. 0.2 to 5 mm), and equal to an integer multiple of a lengthwise groove pitch to avoid or reduce ineffective fragmented cube corners along the tile edge. Each array may have a plane of cant and a primary plane of entrance angularity, and the primary planes of entrance angularity for the multiple tiles may be more evenly distributed in azimuthal angle than the planes of cant.
