  • The European Road Safety Decision Support System on Risks and Measures
  • 2019
  • Ingår i: SAFETYCUBE. ; 08:05
  • Tidskriftsartikel (refereegranskat)abstract
    • The European Road Safety Decision Support System (roadsafety-dss.eu) is an innovative system providing the available evidence on a broad range of road risks and possible countermeasures. This paper describes the scientific basis of the DSS. The structure underlying the DSS consists of (1) a taxonomy identifying risk factors and measures and linking them to each other, (2) a repository of studies, and (3) synopses summarizing the effects estimated in the literature for each risk factor and measure, and (4) an economic efficiency evaluation instrument (E3-calculator). The DSS is implemented in a modern web-based tool with a highly ergonomic interface, allowing users to get a quick overview or go deeper into the results of single studies according to their own needs.

  • The potential of naturalistic driving for in-depth understanding of driver behavior: UDRIVE results and beyond
  • 2019
  • Ingår i: eUropean naturalistic Driving and Riding for Infrastructure & Vehicle safety and Environment (UDRIVE). ; 119, s. 11-20
  • Tidskriftsartikel (refereegranskat)abstract
    • Within the UDRIVE project, a rich cross-European naturalistic driving database was created which includes everyday driving data on car and truck drivers and powered two-wheeler riders. The database provides extensive, reliable insights into driving behavior in real traffic as a foundation for improving the safety and sustainability of European road traffic. This paper discusses the characteristics of the data in the UDRIVE database—elucidating key methodological choices and presenting a selection of results to date. A priority of the study design was obtaining in-depth information on driving behavior, permitting the exploration of diverse research questions. A tailor-made data acquisition system collected very comprehensive data. A total of 287 drivers/riders participated. The sample size restricts the addressable research topics to common behaviors in everyday driving and limits the generalizability of results. However, the data are extensive and promising analyses have already been performed. The results show differences between European countries for distracting activities, seatbelt use, and looking behavior towards cyclists at urban intersections. Moreover, it shows that European drivers engage less in mobile phone use than U.S. drivers. It is likely that European drivers differ in other ways, also—highlighting the dataset's value for developing and implementing targeted safety measures, for the E.U. and its individual countries. Based on the comparison of the different studies, the paper introduces the general conceptual framework for naturalistic driving studies, providing insight in the relation between the scope of a naturalistic driving study and the key methodological choices on sample selection and data acquisition system.

  • FERSI position paper: Safety through automation? : ensuring that automated and connected driving contribute to a safer transportation system
  • 2020
  • Ingår i: Proceedings of 8th Transport Research Arena TRA 2020. ; , s. 5-
  • Konferensbidrag (övrigt vetenskapligt)abstract
    • In 2018, the Forum of European Road Safety Research Institutes (FERSI) published a report on automated driving (AD) from a road safety point of view, prepared by a dedicated FERSI Working Group with experts from eleven European countries. The group identified 23 high priority concerns or questions, clustered into four categories, to ensure that connected AD and co-operative ITS successfully contribute to a smart, green, and integrated transport system which at the same time is a safe transport system. The discussions resulted in ten principles to be fulfilled in order to optimise the safety effects of AD. Even if these principles may seem straightforward, the underlying questions are complex, and the identification and realisation of cost-efficient and effective solutions will require considerable effort. Many strong industrial and political driving forces exist, but so far improving road safety seems to get insufficient priority. FERSI therefore recommends a number of focused actions.

  • Updated estimates of the relationship between speed and road safety at the aggregate and individual levels
  • 2019
  • Ingår i: Accident Analysis and Prevention. - : Elsevier Ltd. - 0001-4575 .- 1879-2057. ; 123, s. 114-122
  • Tidskriftsartikel (refereegranskat)abstract
    • Recent studies of the relationship between the speed of traffic and road safety, stated as the number of fatalities and the number of injury accidents, are reviewed and their results synthesised by means of meta-analysis. All studies were based on data fully or partly for years after 2000. Previously proposed models of the relationship between the speed of traffic and road safety, including the Power Model and an Exponential Model, are supported. Summary estimates of coefficients show that the relationship between speed and road safety remains strong. The Power Model and the Exponential Model both fit the data very well. The relationship between speed and road safety is the same at the individual driver level as at the aggregate level referring to the mean speed of traffic.

  • D1.1. Integrated Framework. Deliverable to the MeBeSafe project
  • 2018
  • Ingår i: MeBeSafe – Measures for Behaving Safely in Traffic.
  • Rapport (övrigt vetenskapligt)abstract
    • The MeBeSafe project intends to develop, implement and validate interventions that direct road users (drivers and cyclists) towards safer behaviour in common traffic situations which carry an elevated risk. More specifically, the aim is to change habitual traffic behaviour using different nudging interventions, i.e. subconsciously pushing road users in a desired direction without being prohibitive against alternative choices of action. The project will also compare different ways of coaching and evaluate the effect of a combination of nudging and coaching. This deliverable, D1.1 Integrated Framework, describes the work completed within WP1 of the MeBeSafe project. Based on literature reviews, interviews with academic and non-academic experts, discussions and workshops, the deliverable: (i) describes the key characteristics of nudging and coaching respectively; (ii) presents a framework that integrates the two, taking into consideration (in particular) time and frequency; (iii) describes underlying theories and models of relevance for understanding road user behaviour; (iii) explains road user profiles or characteristics of relevance to consider in the design of the interventions (i.e., in WP2, WP3, and WP4), as well as the design and interpretation of the outcome of the field trials (in WP5); and (iv) presents design considerations, i.e. factors that should be observed when improving on the initial ideas and further develop the design of the nudging and coaching interventions. More detailed design guidelines must be developed as part of the work to be completed in WP2, WP3, and WP4.
