Urban public transportation is a public welfare service provided by the government for the basic travel needs of the people, as well as a foundational undertaking to ensure the normal operational order of the city and enhance its competitiveness. Prioritizing the development of public transportation is an inevitable requirement for alleviating urban traffic congestion, transforming urban transportation development models, improving the quality of life for the people, and enhancing the level of basic public services. It is also a strategic choice for building a resource-saving and environmentally friendly society.

Bus priority includes two levels of meaning: priority in bus development and priority in bus passage. Its essence is "priority for the people" and "priority for efficiency." Bus priority is a highly complex systematic project that requires policy and regulatory guarantees, supplemented by practical technical measures. To achieve the goal of public transportation priority, it is necessary to rely not only on technical safeguards such as bus network and stop optimization, modernized bus operation management, and bus priority passage methods but also on administrative support in areas such as management system resource allocation and social supervision.

By adopting RFID, video recognition, and GPS positioning technologies, and integrating data such as intersection timing plans, social vehicle green wave schemes, bus schedules, primary and secondary roads, primary and secondary routes, and bus location information, a bus priority control strategy is formed. This allows buses to enjoy right-of-way priority on road sections and at intersections while taking into account the passage needs of social vehicles, granting signal priority to buses. This improves bus operational efficiency, optimizes the proportion of public transportation trips, and alleviates urban traffic congestion.
