2. 1. Incident Traffic Flow Models

   Author : Azita Dabiri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic incident; ramp metering; macroscopic freeway traffic modeling; robust control; incident parameterization;

   Abstract : In the trend toward civilization, transportation has always been considered asan indisputable aspect. However, soon it turned out to be a dilemma in manymetropolitan areas how to assess the increased demand in transportation. The exigency for advanced alternative arises when constructing new roads and infrastructures lost its eligibility due to i. READ MORE

4. 2. Impacts of Traffic Signal Control Strategies

   Author : Azhar Al-Mudhaffar; Karl-Lennart Bång; Nagui M. Rouphail; KTH; []
   Keywords : Driver behavior; Dilemma zone; Incident reduction; Signal control; Lhovra; Spot; Pribuss; Bus priority; Field measurement; Simulation; Calibration; Traffic performance; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Traffic signals are very cost effective tools for urban traffic management in urban areas. The number of intersections in Sweden controlled by traffic signals has increased since the seventies, but efforts to study the traffic performance of the employed strategies are still lacking.

5. 3. Occupant casualties in bus and coach traffic : injury and crash mechanisms

   Author : Pontus Albertsson; Ulf Björnstig; Torbjörn Falkmer; Claes Tingvall; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; bus; coach; aerodynamics; crash; non-crash; cross-wind; injuries; weight distribution; road friction; restraints; haddons matrix; prevention; severe crash; mass casualty; major incident; alighting; boarding; incidents; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Abstract : Background: The relevance of conducting this thesis is evident by the fact that bus and coach casualties have been “stubbornly stable” in Europe recent years and a need for investigating if a similar trend could be found in Sweden is therefore obvious. It was also important to add new knowledge to the bus and coach research in Sweden, since many areas were scarcely addressed. READ MORE

6. 4. Short-Term Traffic Prediction in Large-Scale Urban Networks

   Author : Matej Cebecauer; Erik Jenelius; Wilco Burghout; Balázs Kulcsár; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; travel time prediction; short-term travel time prediction; traffic prediction; clustering; partitioning; spatio-temporal partitioning; large-scale prediction; PPCA; 3D speed map; Transportvetenskap; Transport Science;

   Abstract : City-wide travel time prediction in real-time is an important enabler for efficient use of the road network. It can be used in traveler information to enable more efficient routing of individual vehicles as well as decision support for traffic management applications such as directed information campaigns or incident management.

7. 5. Indicators for traffic safety assessment and prediction and their application in micro-simulation modelling : a study of urban and suburban intersections

   Author : Jeffery Archer; Karl-Lennart Bång; Oliver Carsten; KTH; []
   Keywords : Social sciences; Traffic safety; proximal safety indicators; micro-simulation; safety analysis; Samhällsvetenskap; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

   Abstract : In order to achieve sustainable long-term transport infrastructure development, there is a growing need for fast, reliable and effective methods to evaluate and predict the impact of traffic safety measures. Recognising this need, and the need for an active traffic safety approach, this thesis focuses on traffic safety assessment and prediction based on the use of safety indicators that measure the spatial and/or temporal proximity of safety critical events.
