Technical and scientific foundations for the 2021-2030 Road Safety Strategy - Methodology for the preparation of biennial action plans

Abstract

The Portuguese Road Safety Authority (Autoridade Nacional de Segurança Rodoviária – ANSR) is developing for the Portuguese Government the country’s road safety strategy for the coming period of 2021-2030. The activity comprises three steps: Stage 1, laying out the guiding principles of the National Road Safety Strategy: Vision Zero 2030; Stage 2, consisting in the preparation of technicalscientific reports for the new strategy, including the diagnosis of the current situation and the identification of emerging challenges, the building up of the framework for the new strategy, and the development of a methodology for preparing biennial action plans; and Stage 3, laying out the strategic vision and establishing the Action Plan 2021-2022. Within the scope of these activities, ANSR requested the National Laboratory for Civil Engineering (Laboratório Nacional de Engenharia Civil – LNEC) to provide scientific and technical support to the development of Stage 2, to be delivered jointly with Prof Fred Wegman, from the Delft University of Technology. This report refers to the third activity of Stage 2. The elements to consider while preparing biennial action plans are provided, which follow the Deming Cycle approach and integrate SMART targeted interventions consistent with the framework developed in the second activity. Two examples of the application of this approach are detailed, one regarding speed management in urban areas, through 30 km/h Zone and Home-Zone area-wide infrastructure interventions; and the other covering speed management in interurban roads.
