Publication. National freight model development and application in Finland, Norway, Denmark, Germany and the Netherlands and within the EU has been compiled. This has been done based on questions formulated by the Swedish government agency Transport Analysis. The... Read more... »
Road user effect models – the influence of rut depth on traffic safety
2011-12-12
Publication. One of the main problems within pavement management and maintenance strategies is the relation between road surface condition and accidents, for example the relation between rut depth and accident risk. However, in a VTI study there were no results showing... Read more... »
Report of the first round robin test for mobile reflectometers – Research carried out in the frame of the activities of CEN/TC 226/WG2
2011-12-09
Publication. Mobile reflectometers for measurement of road marking retroreflectivity have been commercially available since the late 1990’s. It has been speculated that measurement errors are larger for these mobile instruments than for the traditional hand-held... Read more... »
Traffic safety effects when overtaking 30 metre trucks
2011-12-09
Publication. There exist small tendencies which point in the direction of enhanced traffic safety problems with the introduction of extra-long trucks. The purpose of a recent VTI study has been to investigate if the introduction of extra-long and heavy vehicles has an... Read more... »
Driver gaze behaviour at cycle crossings in daylight and at night
2011-12-08
Publication. Speed and braking behaviour of drivers do hardly differ between daylight and night when they are to turn right over a cycle path. However, their gaze behaviour differs in daylight and night. Measurements done at VTI show that drivers tend to look at the cycle... Read more... »
Road surface influence on rolling resistance – Coastdown measurements for a car and an HGV
2011-12-07
Publication. The influence of road surface properties, such as macrotexture and unevenness, on rolling resistance and fuel consumption is an important factor to consider when deter¬mining the coating of a road surface. Results of a VTI study show that the effect of... Read more... »
Mobile telephones and other communication devices and their impact on traffic safety – A review of the literature
2011-11-21
Publication. It is difficult to say how dangerous it is for drivers to talk or text while they are driving since it depends on the situational context and the driver's capabilities. Recent studies indicate that the occurrence of crashes, near-crashes and safety critical... Read more... »
