  1. 1. Utvärdering av cykelfälts effekter på cyklisters säkerhet och cykelns konkurrenskraft mot bil

    Författare :Annika Nilsson; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mode choice; route choice; bicycle flow; bicycle counts; level of service; attitudes; speed; lateral position; Road transport technology; behavior; Vägtransportteknik; Bicycle traffic; traffic safety; bicycle planning; bicycle lanes;

    Sammanfattning : This work presents an evaluation of bicycle lane effects on cyclist safety and the ability of bicycles to compete with car traffic. Thirteen Swedish urban streets were studied before and after bicycle lanes were introduced. LÄS MER

    Sammanfattning : The modal share of bicycle traffic in Stockholm increased from 20 per cent to over 30 per cent during the 1930s, and reached staggering levels during World War Two – peaking at over 70 per cent. Soon after the war, however, the share declined rapidly. LÄS MER

  4. 3. 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; []

    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.

  5. 4. Towards microscopic models for bicycle traffic simulation

    Författare :Guillermo Pérez Castro; Johan Olstam; Fredrik Johansson; Heather Kaths; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As bicycling becomes an integral part of sustainable mobility, it becomes essential to enhance planning strategies that ensure bicycling as an efficient mode of transport. While traffic simulation has been extensively utilized for traffic planning of various modes of transport, this type of modeling support is largely lacking in the planning of bicycle traffic.

    Sammanfattning : Aim: To examine the causes and consequences of road traffic injuries in children from a physical and psychosocial perspective, and to identify unfavourable circumstances and children who are at risk of injury and disability. Methods: Study I was a systematic review of the literature on posttraumatic stress disorder (PTSD) and PTSD symptoms (PTSS) in children injured in road traffic accidents. LÄS MER
