PROBLEM TO BE SOLVED: To provide a traffic signal control device capable of reducing the speed of a runaway vehicle, in a surer manner.;SOLUTION: The traffic light control device includes a control means 401B, which performs micro control for individually changing the signaling light color of a traffic light 1, while taking an intersection Ji at a specific point as an object. The control means 401B performs first determination for determining whether a target vehicle 5A, preferably restrained from traveling, can pass an intersection Ji located downstream at the timing of arrival at the intersection Ji and second determination for determining whether a blue-light period on a road into which the target vehicle 5A moves can be reduced at the intersection Ji, when the result of the first determination is positive. Furthermore, when the determination result of the second determination at the intersection Ji is negative, the control means 401B performs the first determination and the second determination for the next intersection Jk downstream of the intersection Ji, when the direction of travel of the target vehicle 5A is used as a reference.;COPYRIGHT: (C)2011,JPO&INPIT
