DATA COLLECTING METHOD IN TAXI DISPATCHING SYSTEM

The automatic vehicle monitoring system (taxi-fleet dispatching system) used for radio control and dispatch of a taxi fleet should collect data of taxi fleet locations and their operating status by using radio channels for dispatch control and communications. It is very important to rapidly collect data necessary for the dispatch control without affecting voice communications in order to efficiently dispatch the fleet. A data collecting system was developed for taxi dispatching, which is applicable for the business radio channels of two-frequency half-duplex--typically used for taxi radio operation. In the new system, such characteristics are so well utilized that the voice communications used in taxi fleet dispatching operation are almost voice communications transmitted from the base station. Two special features of the system are: (1) polling can be performed by synchronizing with the voice communications irregularly transmitted from the base station and (2) the sequential order of polling can be changed according to the status of each taxi vehicle previously gathered. In the case of urgent dispatch of a taxi vehicle, the location data of vacant vehicles available in the area of a certain radius of a specific location can be collected. In addition to these functions, when a taxi vehicle encounters any important circumstances or changes in view of the taxi fleet management, the taxi vehicle concerned can voluntarily originate a transmission of its data to the base station without waiting for the polling sequential order. The taxi dispatching system employing the above mentioned data collecting method is now used successfully throughout Japan.
