Cykling och gående vid större vägar: några aspekter på anläggning, drift och underhåll samt kostnader för GC-lösningar vid större vägar


The aim of the study is to review various aspects regarding construction, maintenance, management and costs for pedestrian and cyclist solutions on major roads, with or without central barrier, where the permitted speed limit is between 70 and 90km/h. Reconstructing an existing road with a central barrier is primarily considered as a road safety measure which reduces the risk of head on collisions. A negative effect of this type of design is that conditions for cyclists and pedestrians become difficult – especially when travelling along or across the road. There are no clear guidelines on how unprotected road users should be considered when reconstructing an existing conventional road to 2+1 road type. The situation of pedestrians and cyclists is not considered to the desired level in the initial planning phase. This often results in the retro introduction of unsuitable measures. The cost of constructing pedestrian and cyclist solutions along major roads depends on geographical conditions and the standard of the solution selected. In addition, construction, operation and maintenance costs for pedestrian and cyclist solutions along and across major roads are not always reported separately. They are often included in the projects' total cost. Increasing the ability to create attractive and cost-effective solutions requires further knowledge. This includes focus on how pedestrian and cyclist solutions should be handled in the initial planning process. It is also important to carry out systematic reviews of existing pedestrian and cyclist solutions along major roads. This will help to give a better idea of construction, operation and maintenance costs.

Simulator used to practice emergency responses safely

Emergency responses of the police, ambulance, and rescue services are associated with a high risk of accidents, but practicing them in real traffic is neither safe nor permissible. A simulator-based method developed by the Swedish National Road and Transport...


Simulation of cut-in by manually driven vehicles in platooning scenarios

A study in a VTI-driving simulator has showed that a platoon will be able to handle a cut in from a manually driven car. The results of this study have recently been presented at two conferences in Japan.
