Abstract:

The winter road maintenance program (WMP) of Vienna is responsible for road maintenance in winter in the interest of traffic security. If necessary, in addition to the services of the municipality, support from private companies can be requested, for instance incase of heavy snowfalls or when sudden black ice occurs. The influence of weather events on the workload of the WMP was investigated in order to assess the possible influence of climate change on the WMP. The aim of the study is to develop a knowledge base on the weather dependence of WMP workload and to examine what changes might be expected, based on climate scenarios. The results of the study could serve the WMP to adapt to these changes in a timely manner. The analysis was primarily based on the assignments of the private companies, and the working hours of municipal services were only used in comparison. Mainly those days were analysed when private companies were operating in the whole city. The external proved to be much more weather dependant than the WMP. The evaluations show that the heavy maintenance vehicle fleet does not respond as sensitive to weather as the private haulers do. The expenditure of human labour will have an even stronger focus on hibernal high times. A reduction of the currently five month services of the WMP down to the three core months - December, January and February - seems realistic, considering today’s rise in temperature. Statistical records of the private road haulers and records of the operating area of the heavy maintenance vehicle fleet will be used comparatively. Especially those days, on which the private haulers were in use throughout the entire city, will be analysed in detail. The statistical records of the private road haulers are too short-lived in order to make an exact statement about the development of days with extreme impacts. It is however noticeable, that nowadays the expenditure of human labour show a smaller sum of working hours as during the beginning of the monitoring period. The total sum of the events per winter is also decreasing. Additionally it comes to notice, that most of the snow-poor winters appeared after the turn of the millennium.
