What is OTP file format?

OTP (Open Transportation Platform) is a file format designed for the exchange of data between transportation and logistics systems. The file format allows for the sharing of information about routes, vehicles, stops, schedules and fares. It is an open standard, meaning it is free to use and does not require any licensing fees from developers. OTP files are based on XML and are used to maintain data integrity across multiple systems. They are designed to make it easy to transfer data between different systems, such as GPS systems and public transit agencies. OTP is used by a number of public transit systems around the world, including in the United States and Europe. The benefits of using OTP are improved data accuracy, faster data transfer, and greater interoperability between various transportation systems.
