A roadside detection system, a roadside unit and a roadside communication method are provided. The roadside unit receives a positioning signal from a satellite positioning system and obtains roadside latitude and longitude coordinates and an initialization parameter coordinate. The roadside unit receives object information of the object. The roadside unit obtains object latitude and longitude coordinates, an object speed, an object acceleration, an object length, and an object heading/direction based on the roadside latitude and longitude coordinates, the initialization parameter coordinate, and the object information. The roadside unit converts the object latitude and longitude coordinates, the object speed, the object acceleration, the object length, and the object heading/direction into a V2V Basic Safety Message format.

Roadside detection system, roadside unit and roadside communication method thereof

A method for switching service channels in a vehicular environment is provided for performing communications between a user unit and a service provider unit according to a switch ratio between a service channel and a control channel in a multi-channel switching wireless communication environment. The method includes the following steps. In response to a message indicating that the service provider unit uses an access mode of an extended service channel, whether information of the switch ratio is stored in service information of the user unit is searched in the user unit according to geographical information of the service provider unit. If the information of the switch ratio is stored in the service information of the user unit in the searching step, the user unit is set accordingly to enter the access mode of the extended service channel.
