Journal article (peer-reviewed)abstract
- Transportation with road ambulances is increasing because of a concentration of hospitals to larger units, with high quality in the acute care of the patients. The concentration implies longer distances to receiving units, which increases the transportation time. The purpose of the present study was to investigate the time difference in ambulance transportation with high speed emergency driving, compared to non-emergency driving in normal traffic pace. Data was collected from 30 emergency high speed ambulance transportations in urban and rural areas. These transportations were then repeated experimentally with an ambulance driving at normal traffic pace. The average speed and duration for the emergency transportations were shorter than for the experimental driving, both in urban and rural areas. The mean time saved was 2.9 min (urban areas) and 8.9 min (rural areas). Regardless of the patient's clinical status or need of care the emergency transportations were carried out in higher speed than the experimental driving. However, patients with life threatening conditions were not included in this study. Procedures and methods should be developed to identify the patients for which fast transportation has clinical relevance to the outcomes.

Injury events among bus and coach occupants - Non-crash injuries as important as crash injuries

Journal article (peer-reviewed)abstract
- A ten year complete data set from the health sector, comprising 284 injured bus and coach occupants from a well defined area, was analyzed. The annual injury incidence was 2 per 10,000 inhabitants, 3/4 were women. In non-crash incidents, 54% were injured; 2/3 while alighting from a bus or coach. In crashes, 46% were injured; 2/3 in collisions with other vehicles and 1/3 in single vehicle crashes. During October-March, 3/4 were injured. In two single vehicle mass casualty crashes in slippery road conditions, high built coaches were hit by so high cross wind forces that they were blown off the road. This crash mechanism has received little attention earlier. Of those injured in collisions with other vehicles, 78% were injured in collisions with other heavy vehicles. Slippery conditions contributed to half of the alighting injuries. The proportion of moderate or more serious injuries (MAIS 2+) was highest in single vehicle crashes (48%) and in alighting and boarding (43%) incidents, and was lowest (5%) in collisions. Every seventh injured was treated as an in-patient on average in five days. Non-crash victims consumed 57% of all in-patient days. Conclusions: The aerodynamic cross-wind factor merits more studies. Injury reducing measures against alighting injuries, addressing especially step height and slippery conditions, may have a great potential to reduce these injuries. Rear-end collisions by other heavy vehicles in urban areas, causing a high number of “whip-lash" injuries, also need to be further addressed. The newly introduced law on compulsory seat belt use in long distance coaches may have a potential to reduce single vehicle crash and some collision injuries.

Utformningskriterier för specialfordon och taxi med hänsyn till rörelsehindrades in- och urstigning

Book (other academic/artistic)abstract
- This publication, which is redated by of a report from the Department of Transportation at the Chalmers University of Technology was a cooperation with the department for disabled/handicapped at Gothenburg University ("Handikapssforskingen" in Swedish). It comprises a number of (real-life) experiments conducted at the laboratory at Chalmers (this on a cut-down and modified automobile body (one of the authours scraped personal automobile). A comment: As was the praxis during this (early) period of time at Chalmers University of Technology, as well as probably at some other universities. This means that frequent and vast academic publication by means of e.g. conference papers and refereed contributions to scientific journals was almost unheard of. At least so for some of the applied science disciplines (today are the situation indeed very different), That is, earlier was the publication in many respects focused on trying to satisfy the executive administrator the research foundation in question. However, various more public (easily accessible) initiatives to publish was judged as being important.
