  2. 1. Vehicle-vehicle Interactions at Roundabouts and their Implications for the Entry Capacity - A Methodological Study with Applications to Two-lane Roundabouts

    Author : Ola Hagring; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsvetenskaper; Social sciences; maximum likelihood; headways; critical gaps; driver behaviour; capacity; Gap acceptance; two-lane roundabouts; Technological sciences; Teknik;

    Abstract : Problem: The thesis deals with the capacity of two-lane roundabouts and with vehicle-vehicle interactions there. Method: The interactions and the corresponding capacity are modelled by gap-acceptance theory. READ MORE

  4. 2. Improving roundabouts for cyclists and visually impaired

    Author : Lisa Sakshaug; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; accessibility; safety; visually impaired; cyclist; roundabout;

    Abstract : Roundabouts are continuing to increase due to their high traffic safety, low delay times and their winning design. However, there are also problems related to roundabouts; the traffic safety for cyclists is unclear or even negative and there are reports of accessibility problems for people with visual impairment.

  5. 3. Performance Assessment of Long Combination Vehicles using Naturalistic Driving Data

    Author : Abhijeet Behera; Sogol Kharrazi; Erik Frisk; Mats Jonasson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The deployment of long combination vehicles (LCVs) is currently in progress in Sweden. LCV refers to heavy vehicles that are longer than 25.25 m, which is the conventional length limit in Swedish regulations. LCVs reduce operational costs, improve fuel efficiency and reduce CO2 emission per ton-km. READ MORE

  6. 4. Traffic Simulation Modelling of Rural Roads and Driver Assistance Systems

    Author : Andreas Tapani; Jan Lundgren; Haris N. Koutsopoulos; Linköpings universitet; []
    Keywords : Traffic; Micro; Simulation; Model; Car following; Rural road; Driver; Fatigue; Rumble strip; Adaptive cruise control; Active safety system; Safety; Evaluation; Overtaking; Traffic lane; Mathematical model; Thesis; Road: Traffic theory; Road: Traffic theory; TECHNOLOGY;

    Abstract : 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. READ MORE

  7. 5. Driver Interaction : Informal Rules, Irritation and Aggressive Behaviour

    Author : Gunilla Björklund; Lars Åberg; Ralf Risser; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Driver interaction; Informal traffic rules; Driver irritation; Aggressive behaviour; Attributional biases; False consensus; Actor-observer effect; Psykologi; Psychology; Psykologi;

    Abstract : On a daily basis drivers have to share the roads with a great number of other road users. To make the driving task possible every driver has to take the intentions and behaviours of other road users into account. In other words, the road users have to interact with each other. READ MORE
