A Modeling of Diagram for Urban Transportation System

Abstract

This paper is concerned with a modeling of diagram for automated urban transportation system. The diagram is aimed at shifting smoothly from one headway to the other in a short time, and it is assumed that the driving time between stations is regarded as constant and the time getting on and off at each station is given as a linear characteristic of headway. In this paper, the stopping time is composed of the time getting on and off and adjusting time, and the train operation model is formulated using the constants of time for departure and arrival of trains. The performance index is defined as a quadratic form concerning the deviation from scheduled headway and the adjusting time, and the problem is treated after all as a quadratic programming with the adjusting time as variable.
