1. 11. Car-To-Car Side Impacts: Development and Validation of Mathematical Models and their Usability for Protective System Design

   Författare :Bengt Pipkorn; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dummy; injury criteria; padding; mathematical simulations; barrier; side impact; car; occupant; airbag;

   Sammanfattning : The objective of the present work was to develop and use mathematical models to establish principles for protective systems for occupants in car-to-car side impacts. The efforts in this work have concentrated on the protection of the thorax and abdomen since these body parts are most frequently injured in side impacts. LÄS MER

3. 12. Modelling and inference of relative collision safety in cars

   Författare :Anna Vadeby; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collision; Mathematical model; Head on collision; Injury; Risk; Car; 91 Road: Vehicle design and construction; 91 Road: Vehicle design and construction; 85 Road: Personal injuries; 85 Road: Personal injuries;

   Sammanfattning : We propose a new mathematical model for relative collision safety in cars. Our present research is restricted to head-on crashes between two cars and we try to determine how much of the injury risk in a crash that depends on car model. The relative risks include the driver populations of the different car models. LÄS MER

4. 13. Computer based statistical treatment in models with incidental parameters : inspired by car crash data

   Författare :Anna Vadeby; Ola Hössjer; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical model; Accident; Statistics; Analysis; Driver; Characteristics; MATHEMATICS; MATEMATIK; 812 Road: Collation of accident statistics; 812 Road: Collation of accident statistics;

   Sammanfattning : Bootstrap and Markov chain Monte Carlo methods have received much attention in recent years. We study computer intensive methods that can be used in complex situations where it is not possible to express the likelihood estimates or the posterior analytically. The work is inspired by a set of car crash data from real traffic. LÄS MER

5. 14. A Traffic Simulation Modeling Framework for Rural Highways

   Författare :Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic; Micro; Simulation; Model; Overtaking; Speed; Headway; Rural road; Electronic driving aid; Mathematical model; Road: Traffic theory; Road: Traffic theory; Other technology;

   Sammanfattning : Models based on micro-simulation of traffic flows have proven to be useful tools in the study of various traffic systems. Today, there is a wealth of traffic microsimulation models developed for freeway and urban street networks. The road mileage is however in many countries dominated by rural highways. LÄS MER

7. 15. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface

   Författare :Mattia Alemani; Ulf Olofsson; Jens Wahlström; Anders Söderberg; Staffan Jacobson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car brakes emissions; transition temperature; working conditions; environmental design; pin-on-disc; Bilbromsutsläpp; övergångstemperatur; arbetsförhållanden; miljödesign; pinne-på-skiva; Machine Design; Maskinkonstruktion;

   Sammanfattning : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. LÄS MER
