Zusammenfassung:	PROBLEM TO BE SOLVED: To determine whether a curve exists just before a crossing or not, and warn of, only when the curve exists, the presence of the crossing in advance. SOLUTION: A crossing detection part 11 detects a crossing in a travelling direction of one's own vehicle or on a route (crossing detection processing), a curve determination means 12 determines whether a curve having a predetermined angle or more exists just before the detected crossing or not, and a warning means 13 warns that the crossing exists ahead the curve when the curve is determined. The presence of the crossing is warned only when the curve exists just before it, whereby facilitating sufficient deceleration before the curve to prevent a crossing accident, and the safety of driving can be thus effectively improved.
