  1. 1. A method for analysing the traffic process in a safety perspective

    Författare :Åse Svensson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; intermediate method; Accidents; pedestrian safety; safety hierarchy; severity; traffic conflicts; interaction; road user behaviour; traffic safety; traffic process; time to accidents; safety indicators; surrogate measures;

    Sammanfattning : The aim of this study is to extend the traffic safety assessment concept to also include normal road user behaviour, thus not only exceptional behaviours such as accidents and serious conflicts. The goal is to provide a framework for a more thorough description and analysis of safety related road user behaviour in order to better understand the traffic safety processes. LÄS MER

  2. 2. Advancing Traffic Safety : An evaluation of speed limits, vehicle-bicycle interactions, and I2V systems

    Författare :Ary Pezo Silvano; Haris Koutsopoulos; Haneen Farah; Karl-Lennart Bång; Alfonso Montella; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic safety; urban roads; posted speed limits; road characteristics; free-flow speed; time headway; vehicle-bicycle interactions; logit model; yielding probability; cooperative systems and warning messages.; Transportvetenskap; Transport Science;

    Sammanfattning : Since the introduction of motor vehicles, the number of fatalities and accidents has been a concern for society.The number of fatalities on roads is amongst the most common causes of mortality worldwide (WHO, 2015).Even in industrialized countries the number of fatalities remains unacceptable.

    Sammanfattning : Microscopic traffic simulation has proven to be a useful tool for analysis of varioustraffic systems. This thesis consider microscopic traffic simulation of rural roads andthe use of traffic simulation for evaluation of driver assistance systems. LÄS MER

  4. 4. A Traffic Simulation Modeling Framework for Rural Highways

    Författare :Andreas Tapani; Jan Lundgren; Karl-Lennart Bång; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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; Traffic Simulation; Rural Highway; Level-of-Serivice; Road safety; safety indicators; Advanced Driver Assistance Systems ADAS ; Other technology; Övriga teknikvetenskaper;

    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
