Tidskriftsartikel (refereegranskat)abstract
- To further understand the needs of the growing population of elderly drivers and create solutions for safe mobility it is important to understand the driving scenarios and aspects in day to day traffic that may be of challenge for this group. More so, individual differences in how drivers perceive their own driving ability may have an effect on how individuals limit their mobility and/or increase their exposure to risk situations, with a potential negative effect on safety. In this study two sets of assessments have been used in order to identify scenarios and aspects needing consideration in creating safe mobility for elderly drivers; an expert assessment using on-road driving together with assessments through semi structured in-depth interviews. This combination also enables categorisation of the drivers, comparing their own perception of their driving performance with the expert assessment based on actual on-road driving. Four different categories of drivers were identified: adequate (positive), over, under and adequate (negative) estimators. A number of important aspects were identified in the study. Adapting speed to the situation and driving too fast, especially on straight roads in the city, is one aspect. Seeking the attention of other road users at intersections and roundabouts is another important consideration identified. Awareness of difficulties related to speed adaptation and attention was low amongst all the driver categories. However, a difference in attitude was seen in the categories with a more humble and acceptant attitude amongst the adequate and under estimator groups, as compared to the over estimators suggesting that the aspect of attitudes is another important factor for consideration.

Värdering av koldioxidutsläpp från svenska transporter : en kommentar
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I denna rapport analyseras problemet kring hur man ska värdera svenska koldioxidutsläpp med hänsyn till EU:s klimatpolitiska ramverk. När någon aktör under EU:s utsläppstak ökar sina utsläpp måste någon annan minska sina utsläpp i motsvarande mån. Eftersom de totala utsläppen härigenom konstanthålls, uppstår inte någon ytterligare klimateffekt och den så kallade skadekostnadsansatsen förlorar därmed sin relevans för dessa utsläpp. Däremot tar någon annan på sig ytterligare minskningskostnader. Det är dessa kostnader som är de samhällsekonomiska konsekvenserna av ökade utsläpp, exempelvis till följd av ökad trafik i Sverige, och det är dessa som forskarna försökt att skatta i denna rapport.

Bilbältesanvändningen i Sverige 2008
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- VTI has observed seat belt use in a number of towns in Central Sweden since 1983. In the original selection of measuring sites, the emphasis was placed on heavily trafficked roundabouts with both through traffic and local traffic. The intention from the beginning was to study passenger cars with back seat passengers since it was expected that these would be affected by a seat belt law a few years later. The observations last year were made over a total of nine days in August-September 2008, approximately one day per measuring point. The total number of vehicles observed was over 53,000 passenger cars and 7,000 other vehicles. When VTI commenced its measurement series in 1983, seat belt use by adult passengers in the back seat was a modest 10 per cent. It increased in one jump to 60 per cent when the law on seat belt use by adults in the car as a whole came into force on 1 July 1986. Today, about 74 per cent of all adult back seat passengers use a belt. The corresponding level for children in the back seat has been consistently about 10-20 percentage points higher. In 2008, close to 95 per cent of all children in the back seat wore a seat belt.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- VTI has observed seat belt use in a number of towns in Central Sweden since 1983. The observations last year were made over a total of nine days in August–September 2009, approximately one day per measuring point. The total number of vehicles observed was over 54,400 passenger cars and 5,900 other vehicles. When VTI commenced its measurement series in 1983, seat belt use by adult passengers in the back seat was a modest 10%. It increased in one jump to 60% when the law on seat belt use by adults in the car as a whole came into force on July 1, 1986. Today, close to 80% of all adult back seat passengers use a belt. The corresponding level for children in the back seat has been consistently about 10-20 percentage points higher. In 2009, about 95% of all children in the back seat wore a seat belt.

- 424 traffic fatalities were recorded in Seoul in 2010 and 227 of them (54%) involved pedestrian crashes. Surprisingly, 40% of these pedestrian fatalities occurred whilst pedestrians were jaywalking, implying that one jaywalker got killed every four days in Seoul and precious lives can be saved if effective methods preventing jaywalk crashes are applied. This research proposes such methods. The approach applied in the research includes literature reviews, collection of demographical and vehicle characteristics, as well as geometric features of jaywalk crash sites. Application of statistical analysis and an examination of jaywalk crashes that occurred during past years were also carried out to understand contributing factors. Important findings from the research indicate that crosswalk spacing rules need to be flexible to allow neighboring crosswalks to sit very closely to prevent jaywalking. Human factor analysis showed that high speed drivers over represent in offenders of fatal crashes whilst jaywalking. In terms of pedestrians, the elderly was the vulnerable age group. More pedestrians were hit jaywalking by taxis and buses. Road and environment factors showed both expected and contradictory results when total numbers of lane or dry/icy pavement conditions were subject to analysis. It is expected that our results will be used in discussing pedestrian safety, as well as understanding increased strategies to prevent pedestrian fatalities.

Kommunikationskampanjer för trafiksäkerhet : handbok för design, genomförande och utvärdering (förkortad version)
- 2010
-
Rapport (populärvet., debatt m.m.)abstract
- Detta häfte är en förkortad version av CAST-handboken för utformning, genomförande och utvärdering av kommunikationskampanjer om trafiksäkerhet.CAST (Campaigns and Awareness-Raising Strategies in Traffic Safety) är ett riktat forskningsprojekt som stöds av Europeiska kommissionen. Det startades som ett led i kommissionens strävan att förbättra trafiksäkerheten med hjälp av effektivare trafiksäkerhetskampanjer. CAST-projektet, som pågick mellan 2006 och 2009, gällde utveckling av tre verktyg för att ge kampanjmakare praktisk hjälp. Tillsammans ger verktygen tydliga anvisningar för utformning och utvärdering av trafiksäkerhetskampanjer. Verktygen är: - en handbok för utformning, genomförande och utvärdering av trafiksäkerhetskampanjer ; - ett utvärderingsverktyg, avsett att vara till hjälp vid bedömning av kampanjens effektivitet; - ett rapportverktyg, som beskriver hur en fullständig och standardiserad kampanjrapport skrivs.CAST-projektet genomfördes av ett konsortium av 19 partner och samordnades av Belgiens trafiksäkerhetsinstitut (IBSRBIVV). Alla större europeiska organisationer med kunskaper om och erfarenhet av trafiksäkerhetskampanjer medverkade – projektet samlade alltså expertis från hela EU.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Level of Service of Safety is a new concept in the field of traffic safety in China and developed countries, it is a quality indicator which is used to describe the road traffic safety situation and roads providing service of traffic safety for traffic participants. Introducing the study status of the Level of Service of Safety in China and developed countries, the definition of the concept, applications and content. In order to objectively evaluate traffic safety performance at low-grade roads, the concept of the level of service of safety for low-grade roads is brought forward, the factors influencing the sections of level of service of safety are analyzed , then linear, the risk of the roadside, traffic volume, the proportion of trucks and 85% speed difference between cars and large vehicles are selected as the evaluations, level of service of safety for the basic sections of low-grade highway is divided into four levels, the grey class whitening function is established to determine the appropriate threshold, Grey Clustering Method is used to evaluate the level of service of safety for low-grade highway sections, and reasonability of the method is validated. The Grey Clustering Method is applied to evaluate traffic safety of actual low-grade highway section, the result shows that the proposed method is reasonable and feasible.
