![]() Utilizing Doppler Radar to Estimate Rainfall Rates for Highway Segments Track: Climate, Weather and Atmosphere Author(s): Nick Chape, Robert Richardson, J. Lambert, Patrick welsh This paper will present findings and the overall methodology for estimating roadway rain rates. In order to accurately estimate rainfall rates along Interstate highways in Northeast Florida for the Florida Road Weather information System (RWIS) in near real time, the investigators developed and implemented a new methodology to geo-locate Doppler radar rain rates. The intent of this project is to geo-locate the National Weather Service's WSR-88D level-2 Doppler radar to specific mile markers along the roadways of interest, to initiate alerts or warnings to drivers. The geo-located Doppler information can then be analyzed, along with the point-specific shed rate of the road, to determine near real-time conditions of ponding and hydroplaning, and also used for historical analysis of accident statistics to establish causality between accidents that occurred and actual hydroplaning potential.
