Methods and systems are provided for selectively using traffic flow data to provide routing options for a vehicle traveling to a destination point. There is provided a method comprising setting a threshold traffic flow data availability level, receiving traffic flow data from traffic flow sensors placed along one or more routes to the destination point, and determining whether the traffic flow data for each route meets the threshold availability level. The method further comprises enabling a flow-based route guidance for those routes for which the traffic flow data meets the threshold availability level. In one embodiment, the flow-based route guidance comprises utilizing the traffic flow data to calculate an estimated time of arrival at the destination point along each route.
