In the proposed model, som
2、e realistic characteristics of train movement are considered, such as the distance headway and the safety stopping distance. Using the proposed traffic model, we analyse the space-time diagram of traffic model, the trajectory of train movement, etc. Simulation results demonstrate that the proposed m

Some complex phenomena can be reproduced, such as the complex acceleration and deceleration of trains and the propagation of train delay.

4、t calculation is used to calculate the velocity and distance profile as a train travels from one station to another. When the theoretical control algorithm of train movement is analysed and evaluated, a computer-based simulation model is necessary. An important problem is how to establish and solve
5、this simulation model. Recently, a number of studies have been performed in this field. However, many characteristic behaviours of train movement remain unknown. What are the mechanisms by which the train delays emerge? How do the tracked trains affect each other? The car-following model is one of t
6、he important traffic models in studying traffic model, and it is used mainly to describe the behaviour of an individual driver. Several car-following models have been proposed, including the early car-following models, and some recent improved models. Since in the car-following model realistic drive
7、r behaviour and detailed vehicle characters are included, it can be used to simulate various traffic flows which are observed in real traffic. In addition, by using the car-following model, some results can be derived analytically. In 1995, Bando et alproposed an improved car-following model, which
8、is called the optimal velocity model. Such an improved model attracts a lot of attention because of its distinctive features in representing real traffic flow. Lately, research has been carried out on extending the optimal velocity model. A well known extended model, called the “general optimal velo
9、city model”, was proposed by Nagatani in 1999 and Sawada in 2001 separately. But most of them focused on analyzing the characters of density wave from the viewpoint of physics. In the present work, based on the optimal velocity car-following model, we propose a new model for simulating train movemen

To our knowledge, this work explicitly shows this effect for the car-following model for the frst time. The remainder
11、 of the present paper is organized as follows. In Section 2, we introduce the optimal velocity model. The principle of the train control system is introduced in Section 3. In Section 4, we outline the proposed model. The numerical and the analytical results are presented in Section 5. Finally, the conclusions obtained by using this approach are presented in Section 6. 2 The optimal velocity model The car-following model describes the motion of a vehicle following its leader vehicle without making a lane change. In the car-following model, a follower vehicle tries to maintain
