The Taoyuan bus dynamic system was upgraded in early October. The Taoyuan City Government Transportation Bureau stated that the new version of the system will introduce AI algorithms and combine it with real-time traffic information from Google Maps to improve the accuracy of the bus's estimated arrival time. Compared with the old version, which is mainly based on historical data, the new system is currently at about 40% conversion progress. It is expected to complete the full switch in early October, and the arrival information accuracy is expected to increase from the current approximately 80% to over 90%.

The Transportation Bureau explained that the conversion between the old and new systems requires passenger transport operators to carry out vehicle settings and switching on a vehicle-by-vehicle basis. The overall conversion progress is currently about 41%, and is expected to reach 95% by September 29, and 100% complete conversion by October 4.

In addition, because some vehicles are still transmitting GPS data through the old system, and due to data conversion and synchronization operations between the old and new systems, some bus dynamic information may have temporary errors in the near future, including the bus schedule not being displayed, vehicle location or estimated arrival time being abnormal, etc.

The Transportation Bureau stated that it has compared schedules, vehicles and GPS data one by one for abnormal routes, and is working with passenger transport operators to accelerate the completion of bus-machine switching and data correction. It also continues to adjust the new system's estimated arrival model. It is expected to complete the relevant processing before October 4; with the continuous switching of trains and machines, continuous data correction and stable system operation, the accuracy of bus arrival information has gradually improved, and individual abnormal buses will continue to be checked and processed.

As for the use of unofficial bus APPs to query information, the Transportation Bureau added that most third-party APPs obtain bus dynamic data through the TDX platform of the Ministry of Transportation. In the initial stage of the new system test switch in September, the data interface between the new system and TDX was also adjusted simultaneously, which affected some information transmission. After confirmation and adjustment, the latest data can now be obtained normally. Third-party APPs that use TDX data do not need to be revised due to this Taoyuan bus dynamic system upgrade.

The Transportation Bureau stated that it will continue to master bus information on each channel to ensure that after the switch to the new system is completed, it will provide the public with more real-time and accurate bus dynamic information.
