This is a gist of all the work that was done during the summer of 2018 under Google Summer Of Code (GSOC) to further improve the PT Assistant plugin which assists mappers in mapping Public Transport systems.

Aim of the Project

To further improve the plugin in a way that it helps mappers in mapping public transport systems with ease. The assistant should become smarter by the end of GSOC and should act as a true assistant with smarter decision making capabilities.

Final Result

The plugin is now much more capable, processing the data in the background and presenting the result to enable the mappers to make decisions especially with new features like Routing helper, Double splitter, smarter Roundabout splitter etc. All the major achievements of this summer have been listed below :

Addition of Routing Helper button to the Relation Editor

A new button in the Relation Editor which aims to help mappers in fixing all the problems in a relation using options that the helper provides.

The Routing helper runs through the selected relation once the button in the relation editor is clicked. It searches for any kind of violation in the existing ways such as one way direction violation or overlapping of ways etc. Then it gives users options to remove those ways and suggests them some solutions in the form of options. The helper also checks if there is any gap present in the relation and thus it also tries to fix them by giving the suitable list of possible solutions as options which the mapper can select to make the relation correct. So the mapper now doesn’t need to care about the ways that are valid and that can be added as the helper already checks the validities and only then does it give any suggestion.
