Cyklisters hastigheter: Kartläggning, mätningar och observation

Many different road users share space on pedestrian and cycle paths, and their speeds may differ greatly. Differences in speed can complicate the interactions between road users which in turn may cause incidents and accidents. The purpose of this...

Cykelfaktorer som påverkar huvudskador: simulerade omkullkörningar med cykel i VTI:s...

In this project, single bicycle crashes have been simulated in the VTI crash safety laboratory. Crash tests including bicycles are scarce and when performed they usually simulate collisions with motor vehicles, although earlier studies have shown...

Kan dubbdäck på cykeln minska singelolyckorna?: friktionstester av cykeldäck i VTI:s...

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...

Vägarbeten på cykelvägar: kunskapssammanställning och problembeskrivning

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...

Mobilapp för mätning av cykelvägars ojämnheter: en studie av möjligheterna

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...

Cyklisters singelolyckor: analys av olycks- och skadedata samt djupintervjuer

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...

Drift och underhåll av tillgänglighetsåtgärder i tätort. För ökad tillgänglighet och...

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...

Statistik över cyklisters olyckor: faktaunderlag till gemensam strategi för säker cykling

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...

Varmsandning på gång- och cykelvägar: Utvärdering i Umeå av för- och nackdelar med metoden

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...

Hållbara turistresor inom Sverige: hinder och möjligheter för resor med tåg och buss

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...

Uppföljning av gång- och cykeltrafik: utveckling av en harmoniserad metod för kommunal...

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...

Cykelvägars standard: en kunskapssammanställning med fokus på drift och underhåll

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...

Jämnhetsmätning på cykelvägar: utveckling och test av metod för att bedöma cyklisters...

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....

Metoder för skattning av gång- och cykeltrafik: kartläggning och kvalitetsbedömning

This report summarises the needs for, and the procedures applied in, estimating the share of total travel represented by pedestrian and cycle traffic, and comprises an analysis of existing data in the form of travel surveys and flow measurements....

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...

Tema Vintermodell: etapp 2, huvudrapport

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...

Tema Vintermodell: olycksrisker och konsekvenser för olika olyckstyper på is- och...

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...
