The invention provides a signal control method for cross-time scheme safe switching, and belongs to the technical field of signal control. Comprising the following steps: S1, judging the period duration of a current scheme, calculating the end period of the period, and obtaining a next period scheme; s2, judging whether the current scheme is the same as the next period scheme or not, if not, executing S3, and if yes, executing S5; s3, judging whether the first stage of the scheme a is the same as the first stage of the scheme b or not, if not, executing S4, and if yes, executing S5; s4, performing safe transition switching preprocessing on the scheme, and updating the lamp color duration of the period; s5, executing signal control according to a set stage and a lamp color sequence; and S6, after the operation of the current period is finished, sending a report, updating a configuration operation, jumping to a next period head, and switching a scheme. The problem of light color jump during switching of a signa
