[ What is claimed is:] [1.]1. An onboard information transmission apparatus provided in a vehicle comprising:approaching detecting means for detecting that the vehicle approaching an intersection on a first road reaches a position at a predetermined distance before the intersection, the first road and a second road intersecting at the intersection;signal transmission means for transmitting a predetermined signal when said approaching detecting means detects that the vehicle reaches the position at the predetermined distance before the intersection, wherein the predetermined signal transmitted by said signal transmission means is used to supply information, indicating that there is the vehicle approaching the intersection on the first road, to another vehicle approaching the intersection on the second road;running state detecting means for detecting a running state of the vehicle; andtransmission control means for controlling, based on the detecting result obtained by said running state detecting means, the transmission of the predetermined signal by said signal transmission means,wherein said running state detecting means comprises time estimating means for estimating a time period from a time said approaching detecting means detects that the vehicle reaches the position at the predetermined distance before the intersection to a time the vehicle reaches the intersection, andwherein said transmission control means comprises determination means for determining whether the time period obtained by said time estimating means is less than a predetermined value, said transmission control means causing said signal transmission means to transmit the predetermined signal when said determination means determines that the estimated time period is less than the predetermined value.
