GENERATING ALTERNATIVE ROUTES
Applicant(s):
TOMTOM DEV GERMANY GMBH [DE] +
Abstract of US2015160025 (A1)
A method of generating routes in an area covered by an electronic map is described. The map comprises a plurality of segments representing navigable segments in the area covered by the electronic map, each segment being associated with jam probability data representative of a likelihood of a jam on the segment. The method involves generating a first route between an origin and a destination in the area, and generating at least one alternative route between the origin and destination using the jam probability data associated with the segments in the area. In embodiments jam and non-jam travel time data is used with the jam probability for a segment to obtain a measure of reliability of the segment under given traffic conditions, which is used to generate the alternate route(s).

METHODS OF PROVIDING TRAFFIC FLOW MESSAGES
Applicant(s):
TOMTOM DEV GERMANY GMBH [DE] +
Abstract of US2015161886 (A1)
A method of verifying and/or improving a message indicative of an event affecting traffic flow on at least a portion of one or more navigable segments is described. The method involves obtaining positional data relating to the movement of a plurality of devices along a navigable stretch including a navigable stretch identified by the message as being affected, and using the positional data to verify and/or improve the message. The positional data is live data and is used to obtain data relating to the speed of travel of the devices along the navigable stretch including the stretch identified by the message. The speed data can be used to determine a spatial extent of the affected stretch and/or an expected speed of travel along the stretch.
