Claim:
1. A computer implemented method of displaying movements of a mobile device on a road network, the road network being represented by an electronic map comprising data indicative of a plurality of segments representing roads of the road network, each segment extending between nodes, the method comprising: matching, by a processor, at least one received position of the mobile device onto a corresponding position on a segment of the electronic map, the matching further comprising at least determining distance offsets between nodes at least for the segment based on a current movement direction and orientation of the mobile device; predicting, by the processor, at least one future location of the mobile device from the matched position on the segment; and displaying, on a display of the mobile device, movements of the mobile device on a graphical representation of the road network, the method further comprising: monitoring, by the processor, the current movement direction and orientation of the mobile device detecting a switch between forwards and backwards driving, and, when the switch is detected, determining new distance offsets between nodes at least for the segment on which a latest received position of the mobile device has been matched based on the current movement direction and orientation of the mobile device.
