  1. 1. Improved road design for future maintenance analysis of road barrier repair costs

    University dissertation from Stockholm : KTH

    Author : Hawzheen Karim; KTH.; Högskolan Dalarna.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik; highway maintenance; highway management; highway design; road planning; road design; highway engineering; road barrier; cable barrier; w-beam barrier; road barrier damages; barrier repair cost.; Vägprojektering för minskade drift- och underhållskostnader; Keywords: highway maintenance; barrier repair cost;

    Abstract : The cost of a road construction over its service life is a function of the design, quality of construction, maintenance strategies and maintenance operations. Unfortunately, designers often neglect a very important aspect which is the possibility to perform future maintenance activities. READ MORE

  2. 2. The use of highway crossings to maintain landscape connectivity for moose and roe deer

    University dissertation from Fakulteten för samhälls- och livsvetenskaper

    Author : Mattias Olsson; Karlstads universitet.; Karlstads universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Biology; Biologi; wildlife crossings; Barrier effect; habitat selection; ecoduct; moose; roe deer; connectivity; conservation; overpass; underpass; highway; exclusion fencing;

    Abstract : Increasingly wildlife managers and land managers are challenged to maintain the viability and connectivity among large mammal populations. Thus, it is important that effective highway crossings are identified and optimized with respect to construction cost, facilitation of ungulate movements, and ability to reduce wildlife-vehicle collisions.

  4. 4. Suspended solids and metals in highway runoff implications for treatment systems

    University dissertation from Stockholm : KTH

    Author : Magnus Hallberg; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Abstract : It is known that traffic is a source of pollutants and that pollutant loads increase with elevated traffic densities. Studies executed in Stockholm, Sweden advocate that highway runoff from roads with an annual average daily traffic (AADT) exceeding 30,000 vehicles need treatment before discharge to the receiving water.

  5. 5. Design and Performance Analysis of Wireless Networked Control Systems

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Burak Demirel; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control; switched systems; optimal control; event-triggered control;

    Abstract : Networked control systems (NCSs) are distributed systems that use shared communication networks to exchange information between system components such as sensors, controllers and actuators. The networked control system architecture promises advantages in terms of increased flexibility, reduced wiring and lower maintenance costs, and is finding its way into a wide variety of applications, ranging from automobiles and automated highway systems to process control, and power distribution systems.
