The Winter Model

The project “Winter Model” started at the beginning of the 2000s. The idea was to try and predict the consequences of different winter maintenance strategies and to calculate the associated socio-economic costs. It is now possible to calculate and...

Requirements to prevent pedestrian falls

Since injured pedestrians due to falling contributes to high costs for society, therefore the attribute requirements on a road surface is of great importance for safety. The requirements shall be appropriate for all who are on the surface, this...

Energy effectiveness depending on choice of winter maintenance classification standard

The Winter Model has been developed within a project called The Winter Model. The aim of the project, which started in the early 2000s, was to assess social and economic consequences of different winter maintenance strategies for road users, road...

The project “Winter Model” started at the beginning of the 2000s. The idea was to try and predict the consequences of different winter maintenance strategies and to calculate the associated socio-economic costs. It is now possible to calculate and...

The potential to identify low friction from macrotexture

The Swedish Transport Administration want to describe the friction condition of the entire national road network. A nationwide friction measurement is practically difficult to manage and very costly, while we are already measuring road surface...

Winter Management Systems…

VTI has developed a model called the Winter Model, a strategic tool to make calculations for the winter road maintenance during the whole winter season and how this affects the societies costs. This report contains a summary of other models used in...

The Winter Model

The project “Winter Model” started at the beginning of the 2000s. The idea was to try and predict consequences of different winter maintenance strategies so that socio-economic costs could be calculated. Using the Winter Model programme, developed...

Are winter road maintenance practices energy efficient?

Snow removal and anti-slip measures on roads are necessary to maintain road safety and a free-flowing transportation system. This is also interesting from an energy perspective as a free-flowing transportation system will use less energy than a...

Travel comfort on winter roads

What can be stated in this project is how a winter road is experienced when compared to snow free conditions, primarily with regard to unevenness and noise. Surveys carried out during the project show that it is possible, without too much...

New regulations for more effective winter road maintenance

Current winter maintenance costs are approximately 2 billion SEK per annum, but good monitoring tools to ensure that this money is distributed and used effectively are lacking. The purpose of this study was to develop a basis for new regulations for...

Road stretch forecasting E6

Road stretch forecasting is a method for forecasting the weather situations or road conditions, especially slipperiness. This project has been a start on implementing the road stretch forecasting technique on Swedish roads. Road stretch forecasting...

Injured pedestrians

The project’s aim was to analyse the importance of the authority or the association responsible for winter maintenance. Did it make a difference in the number of injury cases if it was the road authority or a property association who managed the...

Climate change adaptation of road construction, operation and maintenance

The global climate change is a reality and affecting society and transport systems. Climate change adaptation of transport systems will make the means of transportation more resilient and decrease the risk and magnitude of disruptions. Generally,...

The impact of climate change on the use of anti- and de-icing salt in Sweden

The future needs for winter maintenance will probably be influenced by the climate change in different ways in different parts of the world. As Sweden is a country with several climate zones, the influence of climate change on winter maintenance...

Techniques and methods for more energy efficient winter road maintenance

One important question in winter road maintenance is: How can we make winter road maintenance more energy efficient? There are several factors that can affect how, when and where the winter road maintenance is performed.A RWIS outstation (Road...
