  2. 1. Evaluation of bus priority strategiesin coordinated traffic signal systems

    Author : Johan Wahlstedt; Karl-Lennart Bång; Haris Koutsopoulos; Lars-Göran Mattsson; Kosonen Iisakki; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bus priority; public transport priority; transit priority; PTSP; TSP; traffic signal; traffic signal control; traffic signal control systems; self-optimising signal control; PRIBUSS; SIL simulation; traffic simulation; Transportvetenskap; Transport Science;

    Abstract : Increasing congestion and environmental concerns have evoked an interest in promoting urban Public Transport (PT) the last decades. In 2012 the City of Stockholm adopted an “Urban mobility strategy” stating that public transport, cycling and walking should be prioritised over cars in central Stockholm. 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. Robust Vehicular Communications for Traffic Safety---Channel Estimation and Multiantenna Schemes

    Author : Keerthi Nagalapur; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Safety; Sector Antennas; All-to-all Broadcast; Channel Estimation; Cross-layer Pilot Scheme; Multiantenna Schemes; Vehicular Communications V2X ;

    Abstract : Vehicular communications, where vehicles exchange information with other vehicles or entities in the road traffic environment, is expected to be a part of the future transportation system and promises to support a plethora of applications for traffic safety and efficiency. In particular, vehicle-to-vehicle (V2V) communication promises to support numerous traffic safety applications by enabling a vehicle to broadcast its current status to all the other vehicles in its surrounding.

  6. 4. Computer Vision for Traffic Surveillance Systems : Methods and Applications

    Author : Saleh Javadi; Mattias Dahl; Michael Cree; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Intelligent transportation systems; ITS; Computer visions systems; Systemteknik; Systems Engineering;

    Abstract : Computer vision solutions play a significant role in intelligent transportation systems (ITS) by improving traffic flow, safety and management. In addition, they feature prominently in autonomous vehicles and their future development. The main advantages of vision-based systems are their flexibility, coverage and accessibility. READ MORE

  7. 5. Salient Region Detection Methods with Application to Traffic Sign Recognition from Street View Images

    Author : Keren Fu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; normalized cut; traffic sign recognition; saliency propagation; color distribution; continuous conditional random field; manifold; Salient region detection; adaptive graph edge weights; color contrast; geodesics;

    Abstract : In the computer vision community, saliency detection refers to modeling the selective mechanism in human visual attentions. Outputs of saliency detection algorithms are called saliency maps, which represent conspicuousness levels of different scene areas. READ MORE
