Mobile RWIS A presentation by Wood.

Virtual RWIS Add caption over coloured rectangle on detailed images. Additional pavement temperature forecasts along critical sections of highway; showing differences for localized micro climates; interpolated between 2 or more existing RWIS stations; monitored by mobile RWIS to improve the quality; mobile data is collected (light and dark blue); pavement temperature profiles are developed over time; cold patches are identified along the highway in different weather conditions; localized micro climates are analyzed in more detail.
