Can studded tyres reduce the number of single bicycle accidents?

The purpose of this project was to define a useful methodology for comparing the ice grip of different bicycle tyres and to perform initial measurements. The long term objective is to set up recommendations to winter cyclists regarding bicycle tyres...

An international review of the frequency of single-bicycle crashes (SBCs) and their...

The objective was to study cyclists’ share of transport modes (modal share) and single-bicycle crashes (SBCs) in different countries in order to investigate if the proportion of cyclist injuries resulting from SBCs is affected by variation in modal...

Road works on cycle paths

Using interviews, literature studies and accident analyses, the researchers have gathered knowledge concerning present-day procedures in connection with road works on cycle paths and how they may conceivably affect cyclists in terms of...

Using a smartphone to measure irregularities on cycle paths

In this study the researchers have investigated the possibilities of measuring irregularities on a cycle path with the aid of the accelerometers in smartphones. Smoothness is an important parameter for describing the functional state of the cycle...

Sustainable tourist travel in Sweden

The objective of this study was to analyze the conditions for the transfer of passengers from private car to public transport, primarily train and bus to, from and within a number of tourist destinations in Sweden. The goal was to develop a basis...

Single bicycle accidents

The objective of this project was to study single bicycle accidents, to see how these can be avoided and how the injuries due to these can be alleviated. The in-depth studies of fatal accidents by the Swedish Traffic Administration, and hospital...

Maintenance and operation of accessibility measures in urban areas. For good access all...

The aim of this project was to identify the difficulties associated with carrying out the operation and maintenance of road safety and accessibility measures and to find possible solutions. The focus has been on design in urban areas, with the...

Cycling accident statistics

A total of 153 cyclists were killed between 2007 and 2012, while more than 44,000 were so badly injured that they were admitted to A&E departments. 8,400 of the injured cyclists were seriously injured and 1,100 very seriously injured. Half the...

Warm wetted sand for skid control of walkways and bike paths

Considering the safety of cyclists and pedestrians the winter maintenance service level needs to be improved and there is a need for skid control measures that are effective and, at the same time, reduce the amount of grit spread during the...

Evaluating pedestrian and cycle traffic

This is the second and last report in a project financed by the Swedish Traffic Administration, with the objective to propose a harmonised method for monitoring the proportion of pedestrian and cycle traffic. The method should be used for local...

Measuring the surface evenness of cycle paths

Condition assessment of cycle paths is important for planning and prioritising maintenance measures. In order to promote cycling the assessment methods need to be related to cyclists' needs and not only to the technical condition of the cycle path....

Service levels of cycleways

This is the final report within the research project "Service levels of cycleways" with the purpose of finding the characteristics of an attractive cycleway, and specifying how to maintain cycleways in order to promote cycling. The report is based...

The importance of winter maintenance for cyclists

Single bicycle accidents represent more than 70% of all bicycle accidents in Sweden and the biggest influencing factor is slippery surfaces, mainly caused by ice and snow. In addition, the winter maintenance service level is significant for the...

The Winter Model, Stage 2. Final Report

The aim of the Winter Model is to estimate and put a value on the most important impacts of the strategies and measures in winter road management for road users, road management authorities and society at large. The main report itself is a summary...

Accident risk and consequences of different types of accident in icy and snow road...

The aim of this study is to augment the Accident Risk Model (within the Winter Model) with accident risk and the consequences of different types of accident, in order that the costs of accidents in icy and snowy road conditions may be calculated. We...
