#' @title Spatial dataset of traffic volumes
#'
#' @description The "vehicles" dataset is the spatial data of traffic volumes
#' in Wheatbelt region, Western Australia (WA), Australia, in 2015.
#' The format is polyline. The attributes include road properties (width and length)
#' and traffic volumes of heavy, light and total vehicles.
#' The variable "obs1pred0" defines the the road segments that have observations or
#' to be predicted.
#' More details and data sources can be referred in the Citation Info of the package.
