    A Comparative Study of Railway Planning, Operations and Delays in Japan and Sweden

    Towards an ultimate transit operation, this study focuses on developing a new methodology that grants both time and space-wise priority to transit vehicles under mixed road conditions, with consideration of potential negative impacts on private vehicles. It takes advantages of the rapid-developing wireless communication and sensing techniques and explores the potential of the near-future urban transit operation. A dynamic and on-demand, virtual right-of-way concept is proposed to make significant contributions in improving the operation of urban mixed road transit, particularly in scenarios with medium traffic volume and transit frequency. Furthermore, it overcomes some disadvantages of traditional transit prioritization measures, in terms of ensuring the level of service of transit operation along the whole journey and the efficient usage of the road space etc.
