Uppdatering EVA-kalkylen: nya emissionsfaktorer beräknade med PHEM

The current European emission model, HBEFA, specifies emission factors for different driving patterns and vehicle types. This model does not study the example of individual intersections. This study utilizes the same microscopic model, PHEM...

Möjligheter till minskade koldioxidutsläpp genom trafikledning: en förstudie

Traffic management can affect the emissions of greenhouse gases, mainly through traffic exhaust emissions, but, to some extent, also since efficient traffic management can delay or avoid new investment in transportation infrastructure by...

Rullmotstånd: vägytans egenskaper och dess inverkan

Rolling resistance is an important aspect of the road surface properties in relation to transport energy use and emissions of carbon dioxide (CO2). By reducing rolling resistance, the transport energy efficiency can be improved and the CO2 emissions...

A case study exploring firefighters’ and municipal officials’ preparedness for electrical...

Purpose: This study presents a social perspective on new vehicle technology. It explores the self-reported preparedness of the fire departments (i.e., rescue services) in Sweden’s three largest cities regarding rescue operations involving electrical...

Kriterier för vägbelysning på statlig väg i och i anslutning till mindre tätorter på...

According to the prevailing road lighting guidelines, roads and streets in urban areas should be equipped with road lighting, while roads outside of urban areas normally do not need to be equipped with road lighting. Vägar och gators utformning...

Spatial planning and electric vehicles. A qualitative case study of horizontal and...

The use of electric-powered vehicles (EV) is experiencing a boom in some countries. Much research has been conducted on the technology per se; however, there is a research gap regarding institutional spatial planning practice concerning EVs. Here,...

Ekonomisk och energieffektiv användning av motorvärmare: beräkning av kallstartstillägg

Using an engine heater before starting the vehicle is a way to achieve greater energy efficiency and lower emissions in the transport sector. The purpose of this study is to update the potential savings by using engine heaters in a newer vehicle...

Energy use due to traffic and pavement maintenance: the cost effectiveness of reducing...

There is a potential to reduce energy use of traffic by performing maintenance measures that lower the rolling resistance. However, the overall aim should be to decrease the total energy use in a life cycle perspective, including energy for both...

Revision of criteria for selection of road lighting class: a pre-study

The aim of this project is to investigate the potential in decreasing the energy use of road lighting by a revision of the guidelines regarding the selection of lighting level. The starting point of this work has been the method for selection of...

Elanvändning för längre och tyngre tåg: sammanfattning av resultat, erfarenheter och...

The ELVIS demonstration project aims to analyze how rail freight transports can be performed more efficiently. Hypotheses are that the transport efficiency can be improved by using longer and heavier freight trains and by implementing energy-related...

Ekonomisk och energieffektiv användning av motorvärmare: utvärdering av effekten på...

Test results show that the cold-start effect with increased fuel consumption is reduced most by heating the cooling water, compared to heating the lubricating oil. Starting an engine when it is cold gives rise to higher fuel consumption and...

Kunskapssammanställning över introduktionen av elbilar

This is an overview of the field of electric driven vehicles, aiming to give an overview of the introduction of vehicles and supporting the development of the vehicle electrification. Some current technical solutions are presented, and a possible...

Nuvarande förutsättningar och försök med längre godståg mellan Gävle och Malmö

The second sub-project of ELVIS demonstration project for longer and heavier freight trains aims to analyze the actual conditions for the use of longer trains and to evaluate the trial where a 730 metres long demonstration train (instead of a...

Utveckling av VTI:s modell för beräkning av trafikarbete på svenska vägar

Each year, VTI delivers a description of both a historical description and a prognosis of the annual vehicle mileage using a forecast model. Based on the results from this model a simplified description is made of the future traffic in HBEFA, which...

Life cycle assessment of a road investment: estimating the effect on energy use when...

In the transport sector, major efforts have been concentrated on developing more fuel efficient engines and vehicles. However, the road infrastructure, its operation and maintenance also use energy and do have an effect on traffic fuel consumption...

Utvärdering PHEM-modellen: En förstudie

The Swedish Transport Administration has stated that there is a need to develop the use of micro simulation models of fuel use and emissions of traffic that are used for transport planning. The aim of the project is to perform an evaluation of PHEM...

Energy use generated by traffic and pavement maintenance: decision support for...

VTI has investigated the role of rolling resistance on total traffic energy use and if road maintenance treatments can be a viable option to reduce total traffic energy use. The purpose of the study is to enable road management to better consider...

Andra generationens biodrivmedel: en litteraturöversikt

One of the transport policy objectives in Sweden is that the vehicle fleet should be fossil independent by 2030. To achieve this we should replace fossil fuels with renewable fuels based on biomass. The purpose of this report is to make a...

Potential för en energieffektivare väg- och gatubelysning: jämförelser mellan dimning och...

In order to reduce energy use and its accompanying costs, it is important to have as energy-efficient road and street lighting as possible. The objectives of this project were to provide basic data for different energy efficiency measures for road...

Life cycle assessment of roads and pavements: studies made in Europe

This is a report in sub-project 3 (SP3) in MIRIAM (Models for rolling resistance In Road Infrastructure Asset Management systems). The main aim in MIRIAM is to provide sustainable and environmentally friendly road infrastructure by reducing rolling...

Beräkningar av energiåtgång och koldioxidutsläpp vid byggande, drift och underhåll av...

Typical values have been estimated per km road regarding the use of energy and carbon dioxide emissions for construction as well as maintenance and operation for four separate cases. These cases have been defined from standard motorways, 2+1-roads...
