Abstract

The utility model discloses a wireless guiding system of vehicle traffic. The wireless guiding system is composed of a vehicle position label, a vehicle location detecting terminal, a passenger guiding label, a guiding terminal, a guiding and location tracking server. In the utility model, the guiding terminal recognizes a passenger guiding label and sends to the guiding and location tracking server. The location tracking server receives a vehicle location detection report sent by the vehicle location detecting terminal, and saves vehicle location label ID information in the vehicle location detection report and record the time when the label is detected. After receiving a guiding terminal request, the server identifies a vehicle sequence of the vehicle having the label through retrieving a database according to the passenger guiding label, and visiting a vehicle location label according to the vehicle sequence to detect history record. And the vehicle speed and location are estimated according to a geographic distance between the vehicle location labels and the recorded time difference. The position is taken as a starting point for planning an optimal line between the starting point and the destination. And the optimal line is converted into a guiding instruction to return to the guiding terminal.
