2. 1. Effects of Safety Measures for Pedestrians and Cyclists at Crossing Facilities on Arterial Roads

   Author : Mohsen Towliat; Institutionen för teknik och samhälle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport technology; arterial roads; interaction points; Keywords: traffic safety; pedestrian and cyclist safety; conflict study; behavioural study; experimental site; control site; physical measure; evaluation design; variable message sign; pedestrian and cycle crossing; speed measurement.; 30 50 road environment; Transportteknik; Road transport technology; Vägtransportteknik;

   Abstract : The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical measures and variable message signs, based on three principles, lower speed, no priority and improved and relevant information, are tested within the framework of this project.

4. 2. Optimization of track geometry maintenance : a study of track geometry degradation to specify optimal inspection intervals

   Author : Iman Arasteh khouy; Per-Olof Larsson-Kråik; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Railway infrastructure is a complex system which comprises different subsystems. Long useful life span is one of the important aspects of this prime mode of transport. The useful life length of its assets is highly dependent on the maintenance and renewal strategy used during its life cycle. READ MORE

5. 3. Link and effect model for performance improvement of railway infrastructure

   Author : Christer Stenström; Antti Salonen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Abstract : Railway traffic has increased over the last decade and it is believed to increase further with transportation shifting from road to rail, due to rising energy costs and the demand to reduce emissions. To manage railway infrastructure assets effectively against agreed-upon and set objectives, performance must be measured and monitored. READ MORE
