Energy-Efficient Winter Maintenance Strategies for Road Safety

This presentation by Lina Nordin, PhD student at the University of Gothenburg, explores how to enhance the energy efficiency of winter maintenance practices, specifically salting, by leveraging weather data. It focuses on understanding conditions that warrant maintenance actions based on real-time Weather Information Systems (RWIS) data. The findings suggest a potential 15% energy savings across winter maintenance events, translating to significant reductions in fuel consumption—over 4,462 liters saved each winter. Practical insights [available here](http://www.gvc.gu.se/kontakt+/Personal/Nordin_Lina/).

  1. How to make winter maintenance more Energy efficient Lina Nordin PhD-Student University of Gothenburg E-mail: lina.nordin@gvc.gu.se Homepage: http://www.gvc.gu.se/kontakt+/Personal/Nordin_Lina/

  2. Energy

  3. Energy efficiency

  4. 1st step Understanding how well winter maintenance (i.e. Salting) is performed according to the weather

  5. The maintenance district

  6. RWIS – preset warnings about slippery conditions Moderate Rime Severe Rime Precipitation with tempratures less than 1°C Temperature fall below 1 °C and Precipitation during the last 12 hours

  7. Weather Match + = Days of slippery indication 6 hour intervalls 4 time spans

  8. The results

  9. Energy savings potential • 15% of the about 200 events 30 events, 12750 kilometres winter • 425 km of roads, • Assumed fuel consumption = 3,5 l/10 km. • 3,5 * 42,5 = 149 litres of fuel saved. (1769 gallons) • 4462,5 litres of fuel saved /winter in the district. (53064 gallons)
