Tianan Bus Connects Fleet Safety and Dispatch with Streamax's Integrated Solution

Tianan Bus operates public bus services across districts in Ordos, Inner Mongolia, China. With vehicles running at different times throughout the day, the operator needs dependable equipment for dispatch, passenger information and safety management. Its safety staff also need practical ways to understand driving risks and follow up with drivers alongside daily operations.

The operator's experience with its previous equipment prompted a review of its vehicle systems. Communication faults, difficulties retrieving accident footage and time spent reviewing alerts had made hardware quality and system stability priorities for the upgrade. Before selecting a solution, Tianan Bus visited Streamax's headquarters and existing project sites to examine how the technology worked in operational settings.

Streamax built the project around an integrated vehicle terminal, with SafeGPT supporting the safety team's risk review. Construction began in November 2023 and was substantially completed in June 2024. The solution now supports both everyday bus operations and the work of identifying and following up on driving risks.

Reliable video was an immediate concern. Communication modules in the previous equipment had failed and required replacement on board vehicles. There had also been occasions when staff could not retrieve footage after an accident. These gaps made it harder to reconstruct events and reinforced the need for equipment the operator could depend on.

Reviewing driving behavior involved considerable manual work. Monitoring staff previously collected hard drives from selected buses at night, then watched recordings at increased playback speed to look for violations. Finding a relevant incident meant searching through much longer stretches of video. False alerts from the previous active safety system added further checks to an already demanding review process.

The upgrade also had to fit the operator's vehicles and daily routines. Different bus models used different interfaces and underlying communication protocols. Safety functions, dispatch and stop announcements all needed to work with the on-board equipment. Streamax therefore had to address the installation and integration requirements of each vehicle model as part of the deployment. The team needed to establish how each function would connect to the bus before it could support the people using it in daily service.

Streamax used the A8Pro integrated bus terminal to bring advanced driver assistance, driver status monitoring, blind spot monitoring and surround-view functions into one vehicle solution. This approach reduced the integration work associated with separate devices. The same terminal also supports the operational functions that Tianan Bus uses during daily service.

The implementation team surveyed and tested each vehicle model, adapted interfaces and protocols, and collected basic vehicle data. The project replaced the previous dispatch platform and associated on-board peripherals, while retaining the basic interior LED displays.

Dispatch staff use the new platform for operational dispatch, while the A8Pro handles stop announcements and connects with interior LED and advertising displays. These functions are used in daily operations alongside the terminal's safety functions. The deployment gives the dispatch team and safety team equipment suited to their respective work, within the same integrated bus solution.

For safety staff, SafeGPT provides a more focused starting point for review. It filters alerts, classifies risks and generates event summaries. Monitoring staff can then review footage from the relevant alert period, reducing the need to search through recordings from an entire day. Staff retain responsibility for assessing the event and deciding what action to take.

SafeGPT also brings together a driver's risk records over time in a driver profile. That helps the team identify recurring issues and decide which drivers need closer attention. A profile gives safety staff specific matters to discuss during a conversation with a driver, rather than leaving them to assess isolated alerts alone.

SafeGPT now covers all Tianan Bus vehicles in operation. The operator uses its risk information alongside safety discussions and direct staff intervention. It has also defined departmental responsibilities, staff training and routine checks so that reviewing risks and following up on them form part of everyday management. The technology provides the information staff need to begin that work. The operator's management practices establish who uses it and how the follow-up continues.

From January to October 2026, Tianan Bus recorded a 62.2% year-on-year reduction in total active safety alerts. Average monthly alerts per vehicle fell 63.1%, high-risk alerts decreased 65.9%, and suspected accident alerts declined 12.8%. Monitoring staff now concentrate on the relevant video periods, while driver profiles help safety staff decide where continued attention is needed.

One driver's experience shows how the information supports a practical response. He appeared among the drivers requiring priority attention for two consecutive months. Safety staff and managers investigated his driving circumstances and found that he was having difficulty driving at night. The team adjusted his shifts to avoid night driving where possible and continued to follow up. His subsequent driving performance improved.

The profile had provided a reason to look more closely. The staff's investigation established what was happening, and the shift adjustment addressed the driver's circumstances. For Streamax, this is an important part of the solution's value: helping the customer turn risk information into an appropriate management action.

Over the same January to October 2026 period, not-at-fault accidents at Tianan Bus decreased 12.3% year on year. Total compensation received from other parties for not-at-fault accidents was approximately 24% lower. Streamax's vehicle sensing and SafeGPT risk review support the operator's ongoing safety discussions, interventions and driver follow-up, keeping the technology connected to the people responsible for daily bus safety.
