This paper presents the main results of a research project that was conducted at Madrid Polytechnic University to assess the potential of effectively reducing accident rates in adverse conditions by deploying intelligent transport systems. Traffic accidents that had occurred in the Spanish National System in adverse weather conditions during a 5-year period were studied to identify road sections with an accident record that justified the implementation of specific countermeasures. American and European experience in applying RWIS and Advanced Adverse Weather Motorist Warning Systems (AAWWS) were analyzed prior to the development of three pilot tests for thedeployment of AAWWS at three Spanish network sites. These tests where complemented with an in-depth study of a sample of 259 adverse conditions injury crashes. The results were used to provide an estimation of the crash reduction attainable by the deployment of these systems in Spain. The research showed that the annual savings in social costs of traffic crashes would exceed the total investment needed to deploy the systems. For the covering abstract see ITRD E139491.
