  1. 1. Modelling and Simulation for Evaluation of Cooperative Intelligent Transport System Functions

    Author : Maytheewat Aramrattana; Tony Ingemar Larsson; Jonas Jansson; Kenneth Lind; Statens väg- och transportforskningsinstitut; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Cooperative ITS; Autonomous driving; Traffic mixture; Simulation; Adaptive cruise control; Platooning electronic ; 23 Road: ITS och traffic; 23 Road: ITS och traffic;

    Abstract : Future vehicles are expected to be equipped with wireless communication technology, that enables them to be “connected” to each others and road infrastructures. Complementing current autonomous vehicles and automated driving systems, the wireless communication allows the vehicles to interact, cooperate, and be aware of its surroundings beyond their own sensors’ range.

    Abstract : The results of this work show that the cost efficiency of tendered bus services is similar across all Swedish counties, except for the more high-density counties where efficiency is lower. Considerably lower efficiency is also found for contracts with services run in-house by the Public Transport Authority (PTA), compared to when the same service is run by a private actor. READ MORE
