1. A signal control device comprising:
a memory storing instructions; and
one or more processors configured to execute the instructions to:
acquire first sensor data from a sensor configured to detect a vehicle present in a display direction of a lamp;
determine, based on the first sensor data, whether there is a following vehicle behind the vehicle captured by the sensor, the following vehicle being incapable of visually recognizing a display status of the lamp due to presence of a preceding vehicle;
acquire information indicating whether the road is congested in a traveling direction of the following vehicle from the first sensor data, when it is determined that there is a following vehicle that is incapable of visually recognizing a display status of the lamp; and
change a display pattern of the lamp in such a way that the following vehicle can pass through an intersection according to the information.
