Claim 0:
1. A method for selecting one or more direction based traffic (DBT) intersections for DBT topology stranding, the method comprising:
for each of a plurality of time epochs, determining, by a processor, a representation of a turning speed in a downstream direction for traffic in each of a plurality of lanes of a link immediately upstream of a DBT intersection;
for each of the plurality of time epochs, determining, by the processor, a ratio of a first representation of the turning speed for traffic in a first lane of the link to a second representation of the turning speed for traffic in a second lane of the link;
determining, by the processor, a speed ratio for the DBT intersection based upon the ratios that are determined for each of the plurality of time epochs;
prioritizing, by the processor, one or more DBT intersections for DBT topology stranding based upon the speed ratio for the one or more DBT intersections;
obtaining, by the processor, traffic information for the prioritized one or more DBT intersections;
defining, by the processor, based on the prioritized one or more DBT intersections, a route that provides lane level guidance to a driver or a vehicle indicating a lane of a link of a DBT intersection of which the vehicle should travel, the route indicating the traffic information;
providing to the driver or the vehicle via a user interface, the route; and
providing, by the processor, the traffic information on the user interface.
