APIs for better developer ecosystems

This article discusses the challenges faced by developers in accessing and using realtime public transport data feeds. The four major technical barriers identified are a lack of real-time updates, fragmentation in real-time protocols, problematic data structures, and rate limits. To maximize innovative use of transport data, the author recommends that providers should offer push-based systems for instantaneous updates, support multiple common protocols to increase accessibility, provide varied levels of detail based on user requests, and invest in increasing rate limits to make data more accessible.
