Abstract
The optimal trajectory planning problem for trains under a moving
block signaling system is considered. This optimal trajectory planning
problem is significant for punctuality, energy consumption, passenger
comfort, etc. In a moving block signaling system, the minimum distance
between two successive trains is the instantaneous braking distance
required by the following train plus a safety margin. The constraints
caused by the moving block signaling system are described as nonlinear
inequalities, which can be transformed into linear inequalities using
piecewise affine approximations. The optimal trajectory planning
problem is subsequently recast as a mixed integer linear programming
problem, which can be solved efficiently by existing solvers. A case
study is used to demonstrate the performance of the proposed approach.
