PPS/EDV is a German software development company with its base in Braunschweig. Since 1992, the company has been developing software for telematics and logistics under the product name of cover® (cooperative vehicle routing). A special feature is cover’s tour optimisation for on-demand public transport services with automated integration of fixed line timetables – i.e. on-demand buses functioning as shuttles to fixed lines. cover® is available in German, English and Dutch.
The system cover® is mainly used for Public Transport on Demand – especially for fully flexible Call-a-Bus services. It can be set up for door-to-door transportation or based on busstops only. Used with an integrated timeteble for fixed lines, transport requests are calculated with the flexible service used as shuttles to and from fixed lines. The system refers to fixed lines, if – for a given transport request – there exists a fixed line as an alternative.
