PROBLEM TO BE SOLVED: To provide a signal control system, a central device, a traffic terminal device, and a computer program that make various kinds of processing possible that can be performed by a stepping control scheme for even a table control type of signal control scheme.SOLUTION: The traffic terminal device comprises: a generation unit for generating vehicle sensing information in which measurement information including an on-pulse length and a vehicle detection point of time is divided for each vehicle between a first prescribed time; and a transmission unit for transmitting the generated vehicle sensing information to the central device. The central device comprises: a reception unit for receiving the vehicle sensing information; a traffic index calculation unit for calculating a traffic index at an object intersection on the basis of the received vehicle sensing information; and a signal control parameter calculation unit for calculating a signal control parameter that includes a cycle length, a split, and an offset on the basis of the calculated traffic index.SELECTED DRAWING: Figure 1
