Summary of results, experiences and lessons learned from ELVIS demonstration project for longer and heavier trains

Year:
2014
VTI-code:
N25-2014

Authors: Inge Vierth

The ELVIS demonstration project aims to analyze how rail freight transports can be performed more efficient. This report (VTI notat 25-2014) summarizes the results and experiences from the three previously produced sub reports.

In terms of both energy efficiency and overall efficiency for the rail transports researchers, companies and the Swedish Transport Administration conclude that there is a big need to secure the quality of the data that is produced. This applies to information about electricity consumption and the factors that possibly affect electricity consumption per ...

Competition between land based modes and sea transports for Swedish freight transports

Year:
2014
VTI-code:
R822

Authors: Megersa Abate , Rune Karlsson , Inge Vierth , Lina Jonsson

The project aims to investigate the competition between road and rail transports on one hand and the sea transports on the other.

Shippers choose different unimodal or multimodal transport chains to carry various types of goods in, to and from Sweden. Transport prices are a key factor when choosing the transport chain. Sea transport prices are set on the world market and fluctuate more than prices for road and rail transports. Imbalances in transport flows also affect the intermodal competition, in particular for transports to/from mainland Europe.

According to the ...

Traffic safety and perceptions of safety in the interaction between street environment and a more energy efficient lighting

Year:
2014
VTI-code:
R816

Authors: Annika Jägerbrand

LED lighting or Light Emitting Diodes is a type of light source that is starting to be used in larger scale on pedestrian and bicycle lanes in Sweden and elsewhere. The project's aim was to study the traffic safety aspects of new lights and the interaction with the street environment for pedestrians and cyclists.

This project investigated the lighting conditions, effects on cyclists, and the interactions between lighting, traffic safety, street environmental conditions and/or other effects such as perceptions of safety for three different light sources (mercury vapour 125W, ...

Sustainable transport – opportunities and barriers

Year:
2014
VTI-code:
R797

Authors: Sonja Forward

This report describes the results of a survey including 1.133 people using a questionnaire covering factors that affect traveller´s intentions to cycle and how to get the "reluctant" rider to start cycling.

In the survey, participants were answering different questions based on two different theories (Theory of planned behaviour and The transtheoretical model of change) and were asked to link them to a journey they usually make in a week. Results showed that distance travelled was an important factor influencing modal choice although this was not the only one since attitude, ...

Pedestrians’ valuations of footpaths

Year:
2014
VTI-code:
R806

Authors: Kristofer Odolinski , Gunilla Björklund

The background to this study is an inquiry by the Swedish Transport Administration to develop methods for benefit-cost analyses for pedestrians’ appraisals of their walking environment and how different improvements in the environment affect decisions to walk.

The issues studied are:
1. What type of road do pedestrians prefer when they choose which route to walk?
2. What is the willingness to pay to get more attractive footpaths?
3. How many persons will start to walk if it is built more attractive footpaths?

The third issue was unfortunately not possible ...

Bicycle-friendly cities – the relevance of urban form and infrastructure

Year:
2014
VTI-code:
R769

Authors: Kerstin Robertson , Sebastian Bamberg , John Parkin , Aslak Fyhri

This report presents the results of a study with the overall aim of analysing the extent to which urban form and the design of the transport system can explain the level of cycling in cities. Distance was the most important factor associated with levels of bicycle use.

Bicycle traffic in cities can have several positive effects on quality of life. Despite these benefits bike share varies greatly between cities, both within and between countries, and in many cities there is a large potential for increased bicycle use. Better understanding of the causes of these differences is ...

Analysis of the effects of IMO's more stringent sulfur requirements – Model calculations on behalf of the governmental agency Transport analysis

Year:
2014
VTI-code:
N33-2013

Authors: Inge Vierth , Rune Karlsson

On behalf of the governmental agency Transport analysis VTI has analysed the consequences of the stricter sulphur regulations for marine fuel with the Swedish national freight transport model Samgods.

The base scenario has been compared with, in total, 18 analysis scenarios developed by Transport analysis. The reason for the large amount of scenarios is the fact that both the technical and the economic development (related to the sulfur directive) is uncertain and needs to be taken into consideration.

The results show that the demand for sea transports on the Swedish ...

Development of validation tool and collection of ITS-based validation data for freight models

Year:
2013
VTI-code:
R804

Authors: Rune Karlsson , Inge Vierth , Christian Udin , Pia Larsson-Wijk , Abboud Ado , Fredrik Söderbaum , Magnus Johansson

This report deals with questions concerning validation of the Swedish national goods transportation model, Samgods. To some degree, also more general issues of validation are discussed.

When developing transportation models it is essential to have independent data available that can be used for comparison, validation and calibration. The quality and availability of such data are obvious issues. It is a big advantage if these data cover many different aspects of the model results and are collected on a regular basis.

In the report, a survey of data sources useful for ...

Innovations for sustainable public transport. Experiences and challenges in the Scandinavian countries

Year:
2013
VTI-code:
R799A

Authors: Tim Richardson , Enza Lissandrello , Petter Naess , Aud Tennöy , Frode Longva , Lisa Hansson , Tomas Svensson , Robert Hrelja

In this report we have analysed institutional and planning conditions for public transport in the Scandinavian countries from a comparative perspective, looking at the county of Skåne (Sweden) and the municipalities of Aarhus (Denmark) and Trondheim (Norway). The report considers qualitative case-studies of public transport.

Results show that, from an institutional perspective on roles and responsibilities, it is difficult to speak of a unified Scandinavian public transport model. However, there are common challenges in all the Scandinavian countries. There is a need for new forms ...

Authors: Kerstin Robertson , Gunilla Sörensen , Hans Antonson , Anna Niska , Annika Jägerbrand , Anders Genell , Björn Arvidsson , Katarina Evanth , Nina Hvitlock , Jan Lundin , Hanna Wennberg

When summer holiday is upon us maybe you're thinking of travelling by train or bus instead of taking the car. VTI has studied Swedish tourism and compared both travel time and prices.

Interest in tourism is increasing and according to recent statistics, tourism's total sales in Sweden increased by 6.4 percent to 264 billion in 2011 and the sector employed 160,000 people. The study by VTI, “Sustainable tourism trips within Sweden. Obstacles and opportunities for travel by train and bus” includes travel time, expenses and interviews. The study included three summer destinations, ...
