ISO/IEC 29109-8:2011 is a part of the ISO/IEC 29109 series, which provides specifications for the identification and communication of application services in smart cities. Specifically, ISO/IEC 29109-8 focuses on “Urban context service interface – Part 8: Public transport.”

This standard aims to establish a consistent and interoperable framework for public transport services within smart cities. It covers various aspects related to public transport services, such as:

1. **Service Identification**: Describing the methods and protocols for identifying public transport services, ensuring that they can be easily recognized and accessed by users.

2. **Service Communication**: Defining the communication protocols and interfaces that facilitate the exchange of information between different components of the public transport system, including vehicles, infrastructure, and user devices.

3. **Data Formats**: Specifying the formats for data exchange, ensuring compatibility and consistency across different systems and platforms.

4. **Security and Privacy**: Addressing the security and privacy concerns related to the collection, storage, and transmission of public transport data.

5. **Interoperability**: Ensuring that public transport services can work seamlessly with other smart city applications and services, promoting interoperability and integration.

By adhering to ISO/IEC 29109-8:2011, stakeholders in the public transport sector can enhance the efficiency, reliability, and user experience of public transport services in smart cities. It provides a foundation for the development of innovative solutions that leverage the capabilities of smart city technologies to improve public transport accessibility, sustainability, and performance.
