Abstract: A message transmission method for a roadside equipment includes the following steps. A plurality of external sensor information is received. A road intersection sign phase information and a road map information are inputted. An object position analysis, a speed analysis, and an sign analysis in object moving direction are performed based on the external sensor information, the road intersection sign phase information, and the road map information, and a classification of dangerous objects in different groups is outputted. According to a current transmission bandwidth limitation and the classification of the dangerous objects, a dangerous object message with a higher classification of the dangerous objects is preferentially selected and transmitted within available transmission bandwidth.

Abstract: A security certificate management method for a vehicular network node is applied in a vehicular network. A message is received. Whether a certificate in the message is revoked is determined. If the certificate in the message is revoked, a regional certificate revocation list (RCRL) is generated or updated based on the revoked certificate by the vehicular network node, and the RCRL is transmitted into a communication range of the vehicular network node.

Abstract: An embodiment disclosed a system for collaborative positioning calibration, comprising at least one reference station and at least one client. The reference station uses a known position and a satellite signal transmitted by at least one satellite to compute a pseudo-range difference of the reference station position and the satellite position, and then broadcasts an area calibration data including at least one pseudo-range difference to at least one client. Based on the area calibration data, the client computes at least one pseudo-range calibration data and outputs a calibrated position of global positioning system.

Abstract: A positioning system having an onboard positioning device and a roadside device is provided. The onboard positioning device receives a plurality of first positioning signals and records a positioning moving locus of a vehicle according to the first positioning signals. The roadside device detects a real moving locus of the vehicle. The onboard positioning device obtains the real moving locus from the roadside device, and calculates a positioning calibration value according to coordinates of the positioning moving locus and coordinates of the real moving locus. Furthermore, the onboard positioning device receives a plurality of second positioning signals and calculates and outputs a plurality of calibrated positioning coordinates according to the second positioning signals and the positioning calibration value.
