A visualization of pavement conditions that are evaluated with respect to weather, pavement, and sub-surface variables provides users responsible for roadway infrastructure maintenance and monitoring with information such as depths of accumulated precipitation across “slices” of a roadway for each particular time in a given time period. The accumulated precipitation information contains the depths for each of several different types of precipitation and is shown in three dimensions, where x represents the lane of the roadway, y represents the depths of precipitation, and z represents time. A visualization model generates an appearance of a roadway lane upon which the accumulated precipitation increases or decreases over time corresponding to the results of weather and maintenance acting on that lane. |

1. A method comprising:
ingesting a plurality of input data into a computing environment comprised of at least one processor and a computer-readable storage medium operably coupled to the at least one computer processor and having program instructions stored therein to perform one or more data processing functions, the plurality of input data representing a pavement condition in response to one or more of traffic characteristics, weather information, and existing road conditions for a specified period of time; modeling the plurality of input data to summarize the pavement condition in one or more three-dimensional representations of accumulated precipitation on a roadway, by:
slicing the roadway into one or more representative segments and assigning a depth to each slice,listing, for each slice, an accumulated amount of precipitation of each precipitation type on the roadway, with a first element of a list representing a first end of the roadway, and a last element of the list representing a second end of the roadway, and defining one or more groups each representing an equal portion of a slice's width of the roadway and populated with a corresponding accumulated amount of precipitation, each group having a height representing a total amount of accumulated precipitation of all precipitation types in the group,representing each group by a rectangular prism placed contiguously along an x-axis, wherein for each precipitation type, a prism section is created inside the group, and having a same width and depth as the group, so that each prism section for each accumulated precipitation type is successively created on top of a previous prism section starting from a bottom of the group to visually render one rectangular prism per group, so that each slice represents accumulated amounts of precipitation across the width of the roadway, and responding to a selection of one slice of roadway of interest, and rendering all of the other slices of roadway substantially transparent, while keeping the slice of interest substantially opaque to enable a detailed view of the accumulated amount of precipitation of each precipitation type at any time. |
