METHODS AND SYSTEMS OF PROVIDING INFORMATION INDICATIVE OF A RECOMMENDED NAVIGABLE STRETCH

摘要

A server 402 determines modified flow speed data for each navigable segment of a recommended navigable stretch. The modified flow speed data is determined so as to make the segment more favorable when a route is determined by a navigation device through the navigable network using the flow speed data. The server transmits the modified flow speed data to a set of one or more navigation devices 400 for use by the or each device at least for the purposes of determining a route through the network of navigable segments. Each navigation device then determines a route to a destination using the modified flow speed data.
