  2. 6. Towards computational models for road-user interaction: Drivers overtaking pedestrians and cyclists

    Author : Alexander Rasch; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active safety; vulnerable road users; cyclist safety; driver models; interaction models; overtaking; Euro NCAP; driver behavior; Pedestrian safety;

    Abstract : Introduction: Crashes resulting from a failed interaction between drivers and vulnerable road users, such as pedestrians or cyclists, can lead to severe injuries or fatalities, especially after failed overtaking maneuvers on rural roads where designated refuge areas are often absent, and impact speeds high. This thesis contains two studies that shed light on driver interaction with either 1) a pedestrian or 2) a cyclist, and oncoming traffic while overtaking. READ MORE

  4. 7. Surrogate Measures of Safety with a Focus on Vulnerable Road Users : An exploration of theory, practice, exposure, and validity

    Author : Carl Johnsson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trafiksäkerhet; Indirekta trafiksäkerhetsindikatorer; Oskyddade trafikanter; Videoanalys; Surrogate measures of safety; Traffic safety; Vulnerable road user safety; Traffic conflicts; video analysis;

    Abstract : Surrogate measures of safety (SMoS) are meant to function as tools to investigate traffic safety. The term surrogate indicates that these measures do not rely on crash data; instead, they focus on identifying safety critical events (or near-crashes) in traffic, which can be used as an alternative to crash records.

  5. 8. Driver interaction with vulnerable road users: Modelling driver behaviour in crossing scenarios

    Author : Christian-Nils Åkerberg Boda; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver behaviour; Counterfactual analysis; Pedestrian; Driver model; Active Safety; Bicyclist; Euro NCAP;

    Abstract : Every year, more than 5000 pedestrians and 2000 cyclists die on European roads. These vulnerable road users (VRUs) are especially at risk when interacting with cars. Intelligent safety systems (ISSs), designed to mitigate or avoid crashes between cars and VRUs, first entered the market a few years ago, and still need to be improved to be effective. READ MORE

  6. 9. Reduction of Vulnerable Road User accidents in urban intersections: Needs and challenges in designing Advanced Driver Assistance Systems

    Author : Azra Habibovic; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vulnerable road user; warning; functional requirement; causation; intersection; accident prevention; advanced driver assistance system; infrastructure-car cooperation;

    Abstract : Advanced driver assistance systems (ADAS) can be used to prevent accidents, or to reduce their severity. It is essential to determine what functional requirements such systems should fulfill to meet drivers’ support needs. An understanding of the underlying contributing factors and context in which the accidents occur is therefore crucial. READ MORE

  7. 10. Toward safety promotion among road users : epidemiology and prevention of road traffic injuries in Iran

    Author : Davoud Khorasani Zavareh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Vulnerable road-user; capture-recapture method; surveillance; system; approach; coordination; road-user safety; laypeople interaction; pre-hospital services; grounded theory;

    Abstract : Road traffic injuries (RTIs) are a major public health problem. Iran has one of the highest RTI mortality and morbidity rates in the world. READ MORE
