The starting point was the Lambda architecture, but several important limitations were detected when applying it to a real big data project. To solve all these issues and to be able to develop the project in a more satisfactory manner, the Lambda architecture was evolved, and as a result we have created a new and more flexible architecture. With this new architecture we were able to complete our project successfully, optimizing hardware usage, using a smaller development team and making the final result easier to maintain. Based in our experience, this new architecture, called Phi, seems to be generic enough to be widely applied to big data projects. This architecture, though more specific than Lambda, could improve and make easier the development and evolution of such projects.

A huge number of these trips are taken by people with special mobility needs. In spite of the existence of numerous Websites and apps that provide information about public transport services, there is a lack of information regarding the accessibility of the routes and sites. We are, therefore, working on the development of a technological framework for the processing, management and exploitation of open data, with the goal of promoting accessibility to city public transport within the framework of the Access@city project. In this paper we specifically focus on the design and storage of accessible transport routes, obtained by means of crowdsourcing techniques, in a NoSQL graph oriented database.
