Here is a list of steps that you have to do to have at least a minimal application. You are free to do more in order to realise the main objectives of the application, and make it user-friendly.
-Setup a triplestore. The simplest is to use Apache Jena Fuseki, but you may also install a OpenLink's Virtuoso server (triplestore used by DBpedia in its backend) or Blazegraph (triplestore used by Wikidata) or Stardog (another commercial triplestore that has a free version). A list of triplestores is available on Wikipedia.
-Define or reuse a vocabulary for describing bicycle-sharing stations and their availability.
-Convert static data about the bicycle stations into RDF, and load the resulting data to the triplestore. You can simply generate an RDF file that you load manually to the triplestore, or add the RDF programmatically using SPARQL Update queries.
-Make a website that will allow one to select a city (in a list or on a map) and get the availability of the bicycles, and bicycle stations. There resulting list should be available in HTML with RDFa. You may also make the data available in RDF (Turtle, RDF/XML, or JSON-LD) based on content negotiation.
-While the real time data may be generated on the fly, static data should be extracted from the triplestore using a SPARQL query.
