Abstract: <P>PROBLEM TO BE SOLVED: To generate a safe and appropriate speed control pattern in compliance with the changes in indication of a signal.  <P>SOLUTION: In a vehicle 40 running on a track r1 within a closed section A, a receiver 44 receives an indication signal, corresponding to the identification information of a signal s1, supplied to a track circuit t1. When the vehicle 40 passes a ground-side element b1, an onboard element 42 receives ground-side element information from the ground-side element b1. The ground-side element information includes the distance between the ground-side element b1 and the signal s1, in correspondence with the identification information of the corresponding signal s1, the length of a closed section B, and the length of a closed section C. An onboard device 46 holds the ground-side element information received by the onboard element 42, when the vehicle passes over the ground-side element. Further, the onboard device reads ground-side element information, in correspondence with the same identification information as the identification information received by the receiver 44. Then, the onboard device generates a speed control pattern, based on the ground-side element information and indication information inputted from the receiver 44.  <P>COPYRIGHT: (C)2004,JPO
