OPEN-SOURCE PROJECTS

The projects are mainly related to multimodal navigation service in urban transportation networks based on OpenStreetMap data. Here are some of them:

• Multimodal Shortest Paths Library
• Multimodal Route Planner Python Package
• Multimodal Route Planner Online API Service

A multimodal route planning demo for Munich is available online. It runs on a AWS minimal instance, so please don't give too much pressure on it because that will slow down my blog system. More open-source projects can be found from my Github page.
