  2. 21. Influence Of Road Feature Variables On Accident Rate

    Author : Sarbaz Najib Othman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safe road geometry; accident rate; black spots; accident causation; Traffic safety;

    Abstract : The main objective of this traffic safety investigation was to find critical road parameters affecting accident rate (AR). The secondary objective was to analyze any identified risk factors from a vehicle dynamics perspective. READ MORE

  4. 22. Impacts of Speed Limits and Information Systems on Speed Choice from a Safety Perspective

    Author : Ary P. Silvano; Haris N. Koutsopoulos; Karl-Lennart Bång; Haneen Farah; Johan Olstam; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed choice; urban; roads; speed limits; road characteristics; traffic safety; cooperative systems and warning messages;

    Abstract : Driving a vehicle is considered a demanding task in a complex dynamic environment. For instance, driving a vehicle on urban roads, where motorized vehicles meet vulnerable road users (VRUs) creates a multifaceted environment with difficult trade-offs and interactions. READ MORE

  5. 23. Mimic: A Microscopic Simulation Model for Rural Road Traffic

    Author : Stig O. Simonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer model; time headway; log normal distribution; Chi-Square test; gap-acceptance; rural road network; car-following; traffic simulation model; alignment; sight distance; Kolmogorov-Smirnoff test; software system; statistics;

    Abstract : The purpose of this dissertation is to outline the theoretical basis of a road traffic simulation model, named Mimic, that constitutes the key elements of a system for estimating road user effects and environmental impacts. The simulation model suggested is a microscopic road traffic simulation model and it is structured to be used for networks of rural roads. READ MORE

  6. 24. Target-driven road vehicle suspension design

    Author : Yansong Huang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinematics; compliance; reverse design; target; suspension;

    Abstract : This thesis is focused on suspension hardpoint and bushing compliance design with new reverse engineering methods that are based on kinematics and compliance constraints. The kinematic reverse design method is implemented into a conceptual front axle development. The results show that, using this method, the design lead time is reduced by half. READ MORE

  7. 25. Identifying the Potential of Combined Road Safety Interventions - A Method to Evaluate Future Effects of Integrated Road and Vehicle Safety Technologies

    Author : Johan Strandroth; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evaluation; Road Safety Management; Autonomous Emergency Braking; Safety Performance Indicators; System Approach; Prediction; Integrated Safety; Vehicle Safety Technology;

    Abstract : Health loss in the road transport system is one of the leading global public health problems with approximately 1.3 million people killed annually. In order to have a systematical approach to improved road safety, it has become common practice to form road safety management policies that include target setting and evaluation. READ MORE
