GB/T 22484-2025 in English

Standard Revision Background and Technological Evolution

GB/T 22484-2025, "Specifications for Urban Public Bus and Tramway Passenger Transport Services," replaces the 2016 version and reflects significant technological advancements and updated management concepts in urban public transport services. This revision is based on the GB/T 1.1-2020 Guidelines for Standardization and fully incorporates recent practical experience in smart public transport, barrier-free services, and safe production.

The revision of this standard, spearheaded by years of research and research, was jointly drafted by the Ministry of Transport's Highway Research Institute and 22 professional institutions nationwide. It covers a full range of requirements, from infrastructure to information services, from vehicle configuration to personnel management. Compared to the 2016 version, the new standard has undergone structural optimization and adjustments to better meet the actual needs of modern urban public transport operations.

Analysis of Major Technical Changes

The 2025 version of the standard incorporates 51 significant technical revisions compared to the 2016 version, primarily in the following areas:

In-depth Interpretation of Core Content

Station Facility Specification Requirements

The new standard sets out more detailed technical requirements for station facilities. The platform width has been adjusted from the original uniform requirement to a graded requirement, with a minimum width of no less than 1.5 meters and a recommended width of at least 2.2 meters, ensuring that the average passenger area per person during peak hours is no less than 0.5 square meters. Accessibility requirements require full integration with surrounding road accessibility systems, complying with multiple standards and specifications, including GB/T 33660 and GB 50763. Intelligent facilities are a new highlight, with the standard explicitly requiring the installation of intelligent features such as electronic bus stops at stations where possible, with technical requirements meeting the requirements of JT/T 1307. The standard also includes additional requirements for reserved supporting facilities at stations, preserving space for the future development of smart public transportation. Technical Requirements for Operating Vehicles: Vehicle configuration requirements are further refined. In addition to meeting the grade configuration requirements of JT/T 888, special emphasis is placed on specialized safety features such as instrumentation for the driving area, which must comply with the requirements of JT/T 1240 and JT/T 1241. For routes designed to respect and care for the elderly, low-floor and low-entry vehicles are required, with technical parameters meeting the requirements of GB 19260.

In terms of vehicle maintenance, the standards define daily maintenance, first-level maintenance, and second-level maintenance. Daily maintenance is performed by drivers or dedicated personnel before and after vehicles are dispatched, while first- and second-level maintenance must be performed by qualified repair companies.

Operational Service Personnel Specifications

Service personnel are required to place greater emphasis on professional competence and service quality. In addition to possessing the basic skills required by JT/T 1511, drivers must also be familiar with vehicle performance. Electric vehicle drivers, in particular, must master the controls, indicators, and signaling devices specified in GB/T 4094.2.

Service standards require that services be provided in Mandarin, and multilingual services are recommended in areas with ethnic minorities, dialects, and a high concentration of foreign visitors. Furthermore, behaviors that affect service quality, such as smoking, snacking, and casual conversation, are prohibited during service.

New Requirements for Intelligent Information Services

The new standard includes a separate Chapter 11, "Intelligent Information Services," reflecting the trend of digital transformation. It is required to provide voice-activated and large-font features for aging and barrier-free accessibility, and the update cycle for vehicle dynamic location information should be no longer than 30 seconds. Regarding information sharing mechanisms, if planned factors such as road construction cause changes to bus services, relevant information should be shared with the company 15 days in advance. Information should be dynamically updated for unforeseen circumstances. The update cycle for electronic maps should not exceed three months to ensure the accuracy and timeliness of information.

Dynamic information	Vehicle arrival time, full load rate, etc.	JT/T 1307
Travel planning	Multi-modal transfer plan	GB/T 37113 Series Real-Time Computing Operational Safety Enhancements Safety requirements have been further systematized, with some overly specific regulations removed in favor of emphasizing that drivers should always monitor vehicle warnings, particularly battery-related warnings and risks. New operating procedures have been added for driving over flooded roads or bridges, requiring drivers to stop, inspect the water conditions, and then proceed at a low speed after confirming safety. Emergency response measures are now in compliance with JT/T 999. In the event of a vehicle breakdown, the driver must immediately pull over, activate the hazard lights, and display warning signs in the direction of oncoming traffic. Particular emphasis has been placed on monitoring and addressing battery safety risks in new energy vehicles. Implementation Recommendations and Compliance Guidelines Transitional Arrangements It is recommended that all public transportation companies complete comprehensive benchmarking within six months of the standard's implementation, focusing on the following aspects: Inspect existing facilities and equipment and develop renovation plans based on the new requirements Organize employee training, especially for the newly added intelligent service requirements Improve service quality supervision mechanisms and establish a regular evaluation system Upgrade information systems to meet requirements for dynamic information updating and sharing Key Points During implementation, special attention should be paid to the following: the systematic integration of station accessibility facilities, the installation of protective isolation facilities in driving areas, the upgrading of intelligent information service systems, and the revision and improvement of emergency response plans. Coordination with supporting standards such as GB/T 44724, "Specifications for Accessible Operation Services for Urban Public Buses and Trams," is also crucial. For intelligent facilities such as electronic bus stops, a phased implementation is recommended, prioritizing deployment in corridors with concentrated passenger traffic and gradually expanding coverage. In terms of service time coordination, a coordination mechanism needs to be established with other modes of transportation, such as rail transit and railways, to ensure the continuity of transfer services. Service Quality Evaluation System The new standard establishes a more scientific service quality evaluation system, requiring annual service quality evaluations using a variety of methods, including on-site measurements, intelligent system analysis, and passenger satisfaction surveys. The effective passenger complaint rate is required to be no higher than 10 complaints per million passengers, reflecting the passenger-centric service philosophy. Appendix E provides a detailed service quality inspection list, including evaluation indicators for three dimensions: onboard service facilities, vehicle cleanliness, and in-car service, providing a practical tool for companies to conduct self-assessments.
