selecting the optimized journey plan based on the journey planning request and the robustness of each of the plurality of routes.
2. The method of claim 1, wherein the journey planning request further comprises an optimization request and wherein selecting the optimized journey plan is further based on the optimization request.
3. The method of claim 2, the optimization request comprises a worst case arrival time.
4. The method of claim 2, the optimization request comprises a most consistent arrival time.
5. The method of claim 1, wherein determining an uncertainty associated with each of the plurality of routes is based on a historical data associated with the transportation network.
6. The method of claim 1, wherein evaluating a robustness of each of the plurality of routes to the uncertainty associated with each of the plurality of routes includes determining a worst case travel time for each of the plurality of routes and an expected travel time for each of the plurality of routes.
7. The method of claim 1, wherein the transportation system is a multi-modal transportation system.
8. The method of claim 1, wherein at least one of the plurality of routes through the transportation network from the origin to the destination includes multiple contingent branches.
The claims below are in addition to those above.

2. A fastener clip in accordance with claim 1 wherein the at least one flexible finger is configured to engage the at least one detent when the airbag is in a standby position to limit the movement of a vehicle trim piece with respect to a vehicle chassis when the airbag is in the standby condition.
3. A fastener clip in accordance with claim 1 wherein the body comprises a substantially rectangular shape, and the at least one detent includes a pair of detents formed on opposite sides of the body.
4. A fastener clip in accordance with claim 1 wherein the body comprises a pair of flexible retention legs adapted to secure the fastener clip to a vehicle chassis.
5. A fastener clip in accordance with claim 1 wherein the at least one flexible finger is adapted to secure a trim piece to a vehicle chassis.
6. A fastener clip in accordance with claim 1, wherein the rigid retaining pin further comprises a rectangular trim stop adapted to limit the movement of the trim piece when the airbag is deployed.
7. A fastener clip in accordance with claim 1, wherein the rigid retaining pin further comprises a flexible spring adapted to limit the movement of the trim piece when the airbag is in a stowed position.
8. A fastener clip in accordance with claim 1, further comprising a concave spring adapted to limit the movement of the trim piece when the airbag is in a stowed position, the at least one flexible finger coupled to the concave spring.
9. A fastener clip in accordance with claim 1, wherein the trim piece has a rectangular opening and the rigid retaining pin further comprises a rectangular trim stop adapted to extend through the rectangular opening and retain the trim piece when the airbag is deployed.
10. A fastener clip in accordance with claim 1 wherein the rigid retaining pin further comprises a pair of catch members, the pair of catch members are deformable to enable the rigid retaining pin to be inserted through the opening in the body.
11. A fastener clip in accordance with claim 1 wherein the body further comprises a pair of stops adapted to engage a pair of catch members to limit the movement of the rigid retaining pin after the airbag has been deployed.
12. A side airbag retention system for use in conjunction with a vehicle including a vehicle chassis, an airbag coupled to the vehicle chassis, and a trim piece adapted to cover the airbag, said airbag retention system comprising:
a fastener clip comprising
a body having an opening extending therethrough;
a pair of detents formed in an exterior surface of the body; and
a rigid retaining pin inserted through the opening, the rigid retaining pin having a pair of flexible fingers configured to engage the pair of detents, the flexible fingers configured to disengage from the pair of detents when an airbag is deployed.
13. An airbag retention system in accordance with claim 12, wherein the flexible fingers are configured to engage the pair of detents when the airbag is in a standby position.
14. An airbag retention system in accordance with claim 12, wherein the body comprises a pair of flexible retention legs adapted to secure the fastener clip to the vehicle chassis.
15. An airbag retention system in accordance with claim 12, wherein the rigid retaining pin further comprises a rectangular trim stop adapted to limit the movement of the trim piece when the airbag is deployed.
16. An airbag retention system in accordance with claim 12, wherein the rigid retaining pin further comprises a flexible spring adapted to limit the movement of the trim piece when the airbag is in a stowed position.
17. An airbag retention system in accordance with claim 12, further comprising a concave spring adapted to limit the movement of the trim piece when the airbag is in a stowed position, the flexible fingers coupled to the concave spring.
18. An airbag retention system in accordance with claim 12, wherein the trim piece has a rectangular opening and the rigid retaining pin further comprises a rectangular trim stop adapted to extend through the rectangular opening and retain the trim piece when the airbag is deployed.
