Technical Report
Full-text available
The advancement of GPS technology enables GPS devices not only to be used as orientation and navigation tools, but also to track travelled routes. GPS tracking data provides essential information for a broad range of urban planning applications such as geographical distribution, transportation routing and planning, traffic management and environmen...
Technical Report
Full-text available
GPS tracking of mobile objects provides spatial and temporal data for a broad range of applications including traffic management and control as well as transportation routing and planning. Previous transportation research has focused on GPS tracking data as an appealing alternative to travel diaries. Yet, the GPS based data are gradually becoming a...
Article
Full-text available
Mobility as a Service (MaaS) is considered a strategy that can provide potential solutions for a sustainable transport system. The current literature claims that MaaS can deliver net positive impacts for the transport system. However, whether these impacts are marginal or significant is unclear, as estimations typically are based on a few pilot tes...
Article
Full-text available
Global positioning systems (GPS) tracking data have been widely used to collect mobility data to investigate travel behaviors and identify travel patterns. Some critical travel information, such as frequently visited locations , speeds, temporal changes, can be easily extracted from the raw GPS data. However, travel information like transport modes...
Article
Full-text available
Mobility data, based on GPS tracking, have been widely used in many areas, such as analyzing travel patterns, investigating transport safety and efficiency, and evaluating travel impacts. Transport modes are essential factors in understanding mobility within the transport system. Therefore, in this study, a significant number of algorithms were tes...
Article
Full-text available
To reach the full potential of Mobility as a Service (MaaS), especially its projected positive environmental impacts, the barriers to development and implementation processes must be identified. However, studies identifying such MaaS barriers are rare. Following an interdisciplinary approach, this paper aims to bridge this gap by adding knowledge o...
Technical Report
Full-text available
Mobility as a Service (MaaS) aims to facilitate seamless, intermodal travel, with the goal of providing a sustainable alternative to private car. Mobility as a Service (MaaS) is considered as one of the potential solutions for the sustainable transport sector. Public officials and practitioners have for several years sought assessments of the susta...
Article
Full-text available
Automated vehicles (AVs) have the potential to enhance road capacity, improving road safety and traffic efficiency. Research and development on AVs have been going on for many years. However, when the complicated traffic rules and real situations interacted, AVs fail to make decisions on contradicting situations, and are not able to have control in...
Article
Full-text available
Corporate Mobility as a Service (CMaaS) is a type of MaaS that enables mobility within as well as to and from a worksite for employees. The expected benefits of CMaaS are to support a shift towards more sustainable and more effective work-related transport activities. There is a lack of knowledge regarding the impacts of CMaaS and how its performan...
Article
During recent years, urban building energy modeling has become known as a novel approach for identification, support and improvement of sustainable urban development initiatives and energy efficiency measures in cities. Urban building energy models draw the required information from the energy analysis of buildings in the urban context and suggest...
Conference Paper
To systematically assess the environmental, economic and social impacts of different types of MaaS, a common evaluation framework is essential. Within the KOMPIS project, a framework is developed with a basis in former projects (e.g. MaaSiFiE and IRIMS), complementary literature studies, and workshops involving different stakeholders. The framework...
Book
Working with Swedes is a book written by my colleagues Carin Nordström, Ioanna Farsari, Xiaoyun Zhao and myself. It provides insights into the everyday work-life of Swedish people, describing Swedish social codes at work with the help of entertaining illustrations. If you are Swedish, this book will provide an outsider’s view of how common behavio...
Article
Full-text available
This article explores whether GTS (gaze time on screen) can be useful as an engagement measure in the screen mediated learning context. Research that exemplifies ways of measuring engagement in the on-line education context usually does not address engagement metrics and engagement evaluation methods that are unique to the diverse contemporary inst...
Conference Paper
Full-text available
GPS-based data are becoming a cornerstone for real-time transportation applications. Tracking data of vehicles from GPS receivers are however susceptible to measurement errors. The assessment of the reliability of data from GPS receiver is a neglected issue, especially in a real road network setting and in the phase after data transfer but before i...
Article
A recent surge of interest in building energy consumption has generated a tremendous amount of energy data, which boosts the data-driven algorithms for broad application throughout the building industry. This article reviews the prevailing data-driven approaches used in building energy analysis under different archetypes and granularities, includin...
Article
Full-text available
In a city there are hotspots that attract citizens, and most of the transportation arises when citizens move between their residence and primary destinations (i.e. hotspots). However, an ex ante evaluation of energy-efficient mobility and urban residential planning has seldom been conducted. Therefore, this paper proposes an ex ante evaluation meth...
Article
Full-text available
There are three key actors in forming the sustainable spatial distribution of residency in an area, (local) government, the estate investor and the resident, each with its own objective. Most urban planning studies have mainly focused on the ex-post evaluation of residential development by considering the objective of each actor separately. This pa...
Article
Full-text available
The advancement of GPS technology has made it possible to use GPS devices as orientation and navigation tools, but also as tools to track spatio-temporal information. GPS tracking data can be broadly applied in location-based services, such as spatial distribution of the economy, transportation routing and planning, traffic management and environme...
Research
This file provide all the original GPS tracking data. The data were collected based on an experiment to be applied to justify a proposed method of evaluating the data reliability.
Conference Paper
Full-text available
Optimal location on the transport infrastructure is the preferable requirement for many decision making processes. Most studies have focused on evaluating performances of optimally locate p facilities by minimizing their distances to a geographically distributed demand (n) when p and n vary. The optimal locations are also sensitive to geographical...
Technical Report
Full-text available
The p-median model is commonly used to find optimal locations of facilities for geographically distributed demands. So far, there are few studies that have considered the importance of the road network in the model. However, Han, Håkansson, and Rebreyend (2013) examined the solutions of the p-median model with densities of the road network varying...

Archived project
This project aims to provide reference values of MaaS by evaluating its impacts on environmental, economic and social aspects through a selection of representative scenarios. The project will explore how and to what extent MaaS leads to, for example, reduced emissions, reduced energy consumption and increased travellers’ satisfaction, generating knowledge that can support decision-making within both public organisations and among service developers.
Project
The project Grip on Emissions shall produce a model for reporting, analysis and adaption of the turnover of energy and matter of the business. The work name of the model is Environmental Logistics System Application (ELSA). In the first round ELSA will be utilised to follow up and thence bring down climate affecting emissions from contract works to sustainable levels. The model uses standardisation and will be dissipated in the industry and to other countries, starting within the E. U. The model is developed in collaboration with researcher investigating the utility of data for analyses and optimisations in a BIG data context.
