  1. 1. Mimic: A Microscopic Simulation Model for Rural Road Traffic

    Author : Stig O. Simonsson; Chalmers University of Technology; []
    Keywords : 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

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

    Author : Ary Pezo Silvano; Haris Koutsopoulos; Haneen Farah; Karl-Lennart Bång; Alfonso Montella; KTH; []
    Keywords : 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;

    Abstract : 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.

  3. 3. Modelling and Appraisal in Congested Transport Networks

    Author : Jens West; Maria Börjesson; Oded Cats; Leonid Engelsson; Giulio Cantarella; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport modelling; Transit Assignment; Appraisal; Congestion; Crowding; Cost-benefit analysis; Value of time; Congestion charge; Dynamic traffic assignment; Transportvetenskap; Transport Science;

    Abstract : Appraisal methodologies for congestion mitigation projects are relatively less well developed compared to methodologies for projects reducing free flow travel times. For instance, static assignment models are incapable of representing the build-up and dissipation of traffic queues, or capturing the experienced crowding caused by uneven on-board passenger loads.

  4. 4. The Public Transport Preferences of Elderly People; A study related to individual capacity and environmental stress in service route traffic and other systems

    Author : Helena Svensson; Trafik och väg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; walking distance; valuation; standard factors; conjoint analysis; stated preference method; trunk routes; special transport; service routes; restrictions; physical capacity; preferences; travellers; public transport; elderly people; traffic planning; Road transport technology; Vägtransportteknik;

    Abstract : Providing accessible, acceptable and appreciated public transport for elderly people is essential. This work studies the relation between elderly people’s preferences of standard factors in different public transport systems, and their physical capacity. READ MORE

  5. 5. Assessment of Robustness in Railway Traffic Timetables

    Author : Emma V. Andersson; Jan Lundgren; Anders Peterson; Johanna Törnquist Krasemann; Thorsten Büker; Linköpings universitet; []
    Keywords : ;

    Abstract : A tendency seen for the last decades in many European railway networks is a growing demand for capacity. An increased number of operating trains has led to a delay sensitive system where it is hard to recover from delays, where even relatively small delays are easily propagating to other traffic.
