How do drivers evaluate fines for different traffic offences? A literature study

Year:
2007
VTI-code:
R574

Authors: Sonja Forward , Hans-Åke Cedersund

The most common sanction for most traffic offences in Sweden is a fine, but it is only one of several sanction options for society. If one is caught driving without a safety belt, and other similar minor traffic offences, the sanction is always a fine of fixed sum. For minor speeding offences a fixed sum is also charged. It is only for excessive speeding that a court may adjudge the confiscation of the driving license for a shorter or longer period. For drunken driving fines are not used at all. Instead a monetary fine, i.e. a fine assessed on the basis of the defendant’s daily income, will ...

A quality evaluation of a travel survey. A study of sampling errors, nonresponse errors and measurement errors

Year:
2007
VTI-code:
R575

Authors: Anna Vadeby , Åsa Forsman , Susanne Gustafsson

TSU92- is a travel survey that started in 1992, and the aim was to increase the knowledge of unprotected road-users; both with respect to how much and where they travel and their use of safety equipment such as helmets and reflectors. The survey is still focused on the unprotected road-users, but questions about car use and use of public transportation are also included. The response rate has been around 55 percent the last years. An evaluation of the quality of the survey is presented in this report and some suggestions on how to improve the survey is given. The study is limited to three ...

VMS – Variable Message Signs. A literature review

Year:
2007
VTI-code:
R570A

Authors: Gabriel Helmers , Sara Nygårdhs

The acronym VMS stands for Variable Message Sign. It is a sign for the purpose of displaying one of a number of messages that may be changed or switched on or off as required (CEN, 2005).

This literature review is primarily aimed at describing studies that deal with the interaction between driver behaviour and VMS. The collected references are, for the most part, published in Europe or studies about European conditions, published during the years of 2000 2005.

Areas treated in the study are effects on driver behaviour, driver attitudes, design, understanding and recall ...

Passing a bus with 30 km/h. Assessment of safety effects of a speed limit of 30 km/h when passing a bus – a simulator study

Year:
2007
VTI-code:
R573

Authors: Albert Kircher , Birgitta Thorslund , Torbjörn Falkmer , Katja Kircher , Anna Anund

A simulator study was conducted to investigate the implementation of a new law which
prescribes a speed limit of 30 km/h when passing buses equipped with a 30-sign and
flashing lights. It was shown that the drivers follow the rule better when they pass a bus
on their own side than when the bus was standing on the opposite side of the road. The
slowest mean speeds were found when passing a bus on a road with a speed limit of
70 km/h. The highest speed reduction, however, was found when the posted speed limit
was 90 km/h. A bus without signage did not induce the ...

The SARTRE 3 Tables – Another set of opinions about traffic and traffic safety of European drivers

Year:
2006
VTI-code:
R541/541A

Authors: Sven Dahlstedt

SARTRE is an acronym for the project "Social Attitudes to Road Traffic Risk in Europe", which implies a collaboration between a number of organisations in the field of traffic safety and road traffic research in Europe to carry out coordinated surveys. The first phase of the project started in the early 90's and then it included about 16 countries in Western and Central Europe.

In the third round of the continued Sartre project, reported here, new interviews were conducted with European drivers to study their attitudes to traffic and traffic safety. This time the questionnaire ...

Children’s perspective on safety and security in school transportation

Year:
2006
VTI-code:
R548

Authors: Jonna Nyberg , Anna Anund , Torbjörn Falkmer , Kerstin Elkehag , Charlotta Elm , Pamela Gustafson , Anna Lövgren , Pia Åkerberg

School transportation should be safe, secure and accessible for all children entitled to such transportation, regardless of any disability. On a daily basis, 440,000 children utilise school transportation, several thousands of them having some sort of disability. Laws, rules and regulations concerning school transportation do not take the children’s perspective into account. Moreover, they do not explicitly define where and when a school transport actually starts and ends. For these reasons, more knowledge was needed in order to fully understand why school transportation incidents take place. ...

Road and road surface design for safety, comfort and health – A pilot study

Year:
2006
VTI-code:
N29-2006

Authors: Peter Andrén , Anita Ihs , Leif Sjögren , Selina Mårdh

During summer 2002 a special directive about employees’ health and security at exposure to risks due to vibrations during work, also called “Physical agents vibration directive” (Directive 2002/44/EC), was adopted by the EC. The member states had until July 6th 2005 to transfer the directive into the national legislation.
Certainly the condition of parts of the road network can be such that the vibration levels that professional drivers are exposed to exceed the limits that are given in the vibration directive. VTI has therefore been commissioned to carry out a pilot study including a ...

Mobility and travel patterns among foreign-born in Swedish traffic environment

Year:
2006
VTI-code:
R546

Authors: Jonna Nyberg , Susanne Gustafsson , Catharina Lewin

Approximately 12% of Sweden’s inhabitants were born in another country. The proportion of foreign-born that possess driver’s licences and vehicles is lower than among Swedish-born, which limits the ability to travel among this group. This is one important result of the present study, which was financed by the Swedish Road Administration. The aim of this study was to increase knowledge concerning the situation for foreign-born in the Swedish transportation system and analyze their mobility and travel patterns. The results are based on a literature review, register data, group interviews as ...
