“emma” (E)Mobilizes Lake Constance

by Daniel SchmidtMay 23, 2014

Electro mobility gets even more attractive with “emma”: The new journey planner offers passengers an extensive range of services in the area of Lake Constance. At the e-mobility-world 2014 in Friedrichshafen (Germany) from May 23-25, the project partners introduce the HAFAS-based app that facilitates intermodal door-to-door navigation and is now also available for iPhones.

The “emma” project is sponsored by the German Federal Ministry of Transport and aims to minimize passengers’ waiting times while they travel through the rural regions around Friedrichshafen and the Lake Constance district. Therefore, e-cars are provided to complement public transport services. In order to make it as easy as possible to get from A to B, HaCon developed a journey planner that links bus and rail connections with private transportation and helps to promote e-cars as an integral part of public transport within the region. 

The service is available on and as an app for Android and iOS. After searching a connection, the user can see right away whether there is an “emma” e-car available and how it can be reached. The journey planner has a multitude of useful functions that facilitate traveling: for instance, delays and alternative connections are displayed in real time. Dynamic maps enable exact routing, whether heading for a certain address, a stop or a charging station. The density of information on the map automatically adapts to the zoom level: With a single click, it is possible to display route networks and stops for different means of transport as well as “emma” charging stations.

The departure boards show all departing and arriving vehicles for any station and stop and are particularly user-friendly regarding their design and function. Thanks to the proximity search that links geocoded data with the journey planner, users can choose destinations according to their distances in travel time by bus, rail, car, bike or foot.
