Abstract:

This paper describes a Road Weather Information System (RWIS) data archive and web access facility recently developed by the Traffic Operations and Safety (TOPS) Laboratory at the University of Wisconsin-Madison. Currently, Wisconsin DOT (WisDOT) maintains an RWIS data collection system primary to support winter maintenance operations activities. The objective of developing the TOPS RWIS data repository is to facilitate wider application of the RWIS data for research and operations such as integration with crash and traffic count data, performance analysis of the existing RWIS system itself, and support for WisDOT Clarus initiatives. The design of the archiving system addresses three major technical challenges: data archiving efficiency, data densification, and data accessibility. Data archiving efficiency refers to minimizing processing overhead during the download and database import process. It also includes the use of redundant components to minimize data loss during potential hardware or system failure. Data densification refers to a process whereby raw RWIS data, which is generally sampled at irregular intervals, is presented to the user on a full timestamp grid. The system employs two interpolation algorithms to provide alternate dense representations. Data accessibility refers to the development of tools to provide convenient access to the data. The web facility component provides an online data query and export tool based on Java web application technologies.
