What are space separation method and time separation method?

Legal analysis: 1. The time interval method means "the train runs every once in a while". 2. The method of space separation means "the train runs every once in a while".

Legal basis: The section divided by stations or lines and the automatic blocking section divided by signals are the methods of running sections, which are called space separation method. Spatial segmentation method is divided into basic block method and alternative block method. The basic blocking mode adopts one of "automatic blocking, automatic blocking between stations and semi-automatic blocking". Telephone blocking method is used as a substitute for blocking method.
