<p><P>PROBLEM TO BE SOLVED: To provide a signal control determination device, a computer program and a signal control propriety determination method for determining the propriety of signal control at an intersection. <P>SOLUTION: An acquisition number calculation part 107 calculates the acquisition number of probe information acquired from a vehicle which has traveled on a major road R1 and a minor road R2 in an arbitrary time zone. A determination part 105 determines the propriety of signal control at an intersection on the basis of the rate of the acquisition number on the major road R1 to the calculated acquisition number on the minor road R2 or a difference between those acquisition numbers. For example, when the rate of the acquisition number on the major road to the acquisition number on the minor road or the difference between those acquisition numbers is equal to or more than a predetermined threshold, the determination part 105 determines that the intersection is a semi-sensitive object intersection. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
