- The objective of this paper is to describe the evaluation and effects of a major reconstruction of an arterial street in Eskilstuna, a medium sized Swedish town. The aim of the reconstruction was to minimize the barrier effects of the arterial street and by that create a stronger connection between the town center, on one side of the street, and the town-river, on the other; but also to create generally better conditions for primarily unprotected road users in that area of the city. This paper studies how traffic safety, subjective safety, pass ability, accessibility, attraction, aesthetics and air pollution are influenced by this reconstruction. Both objective and subjective measurements have been used. The reconstruction gave positive effects on most of the aspects studied and although the primary aim of the project was not to improve traffic safety the results were very positive in this respect as well. The most negative outcome was an increase in car emissions due to more accelerations and decelerations. In total the positive effects are overriding the negative ones by far and the study shows that by making some sacrifice in the mobility and comfort for motor vehicle occupants the attraction and esthetics of the area has increased as well as the traffic safety. An attempt has also been made to value the changes regarding different aspects for different types of road users. This clearly shows the stronger benefits for unprotected road users compared with the motorists.

The effects of Large Scale use of active accelerator pedal in urban areas

Konferensbidrag (refereegranskat)abstract
- Within the framework of the Swedish national trial with Intelligent Speed Adaptation (ISA) in urban areas, the effects of large scale use of “active accelerator” were evaluated. 284 cars were equipped with the system for a period of 5-11 months in the city of Lund. The driving data of all equipped vehicles were logged with regard to time and speed, both before and after activating the system. Driver behaviour and workload were studied with the help of an instrumented vehicle. Possible system effects, such as speeds, interactions with other road-users and driving against red were studied in the field. Possible changes in driver attitudes and acceptance were studied by interviews. The results revealed that test drivers’ compliance with the speed limits increased both according to their own statements and objective measurements. At this stage practically no negative compensatory effects could be found.

Actors’ expectations and requests regarding ISA implementation.
- 2003
-
Konferensbidrag (refereegranskat)abstract
- The stake holders seem to be pending on each others reaction towards ISA-systems (Intelligent Speed Adaptation). A situation can occur in which the car owners do not invest in the system because the car industry do not believe in it, the car industry waits upon the politicians’ standpoint, and the politicians leer at the public opinion… Decision makers need a good picture of what decisions are needed in order to make the car industry produce the system; to make companies with fleet of vehicles invest in the system; to make purchaser of transport services demand the system; to make the insurance companies reward drivers with the system etc. The manufacturers need straight answers of the standpoint of the decision makers and how big the demand among companies with fleets of vehicles is. Private car drivers and companies with fleets of vehicles need to know what support they can expect from the government or from the insurance companies. The study is based on explorative studies were the different stake holders’ attitudes, interests, needs, expectations are explored and the differences between the stake holders are analysed. The stake holders are categorized into four different groups: – Stake holders keen to improve traffic safety (politicians and insurance companies) – Manufacturer (car industry) – Catalysts (opinion makers) – Users (privet car drivers, companies with fleet of vehicles, car rental companies etc.) The aim of this paper is to describe the hypotheses and methods of the study.
