2. 1. Modelling and Appraisal in Congested Transport Networks

   Author : Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

   Abstract : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

4. 2. Simulation of rail traffic : applications with timetable construction and delay modelling

   Author : Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). READ MORE

5. 3. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements

   Author : Annika Lundmark; Per-Erik Jansson; Bo Olofsson; Ann-Catrine Norrström; Helen K. French; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chloride; De-icing salt; Groundwater; Modelling; Monitoring; Road; Roadside; Soil water; Water in nature and society; Vatten i natur och samhälle;

   Abstract : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. READ MORE

6. 4. On the impact of noise and energy demand from traffic : An assessment using microscopic modelling

   Author : Johan Nygren; Susann Boij; Romain Rumpler; Ciarán J. O'Reilly; Arnaud Can; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic simulation; sustainable transport; noise emissions; environmental impact; energy efficiency; Trafiksimulering; hållbar transport; buller; miljöpåverkan; energieffektivitet; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : Noise emissions from transportation remain one of the greatest environmental issues of modern day. Inhabitants in urban environments are especially exposed, with almost 80 million people in the European Union exposed to noise levels exceeding the recommended limits set by the World Health Organization (WHO).

7. 5. Dynamic Modelling of Transit Operations and Passenger Decisions

   Author : Oded Cats; Haris Koutsopoulos; Tomer Toledo; Wilson Nigel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Public Transport; Transit Operations; Simulation Model; Traffic Simulation; Route Choice; Dynamic Model; Assignment Model; Control; SRA - Transport; SRA - Transport;

   Abstract : Efficient and reliable public transport systems are fundamental in promoting green growth developments in metropolitan areas. A large range of Advanced Public Transport Systems (APTS) facilitates the design of real-time operations and demand management. READ MORE
