| Project | Mobile Traffic | | |   | | Time Period | | | Customer | | | Subject | - September 2005 OneStepAhead started designing and developing a traffic information application on smartphone devices called “Freie Fahrt Mobil”. The goal was to use existing web-based services in order to build highly extendible client-server-based mobile application.
- The main features are:
- real-time traffic messages over GPRS
-
text-based traffic reports, including free text info -
fully localized application, supports 11 languages -
interactive maps showing the traffic incident's location -
personal profiles allow users to set road filters, sort ordering, update interval, appearance, etc. -
supports bluetooth GPS devices (JSR-82 compatible smartphones) -
shows user's current position (GPS) on map, using GPRS connection -
filters traffic messages by user's location and driving direction -
does not read or store maps or traffic info on device
- MobileTraffic is a J2ME Midlet application which basically runs on any MIDP 1.0/2.0 and CLDC 1.0/1.1 Java smartphones and is 100% implemented in Java. It does not use any vendor or device specific features in order to allow the application to run on any J2ME phone.
- The GPS-feature is only available on GPS-enabled phones and/or smartphone with JSR-82 bluetooth and a connected GPS receiver.
- Due to it's minimum hardware requirements the basic MobileTraffic application potentially runs on hundreds of different smartphones like Nokia, SonyEricsson, Motorola or Samsung devices.
- MobileTraffic makes use of a simple but very intuitive user interface which currently supports a German and English vocabulary. A new language is integrated by simply creating and adding a new resource file to the installation package. After launching the application it reads the user's current language setting and automatically switches to his preferred locale.

MicroMap MultiSource ConceptAny feature inside MicroMap itself defines where it's content is located or stored. Some features may be stored on the local storage (e.g. road network, places, adresses, etc.), others may reside on the network (e.g. traffic information, POI content, etc.). The MicroMap configuration file defines where a certain feature type is located.
