The feature that allows for traffic routing based on latency in Amazon Route 53 is the latency routing policy. This policy is specifically designed to direct users to the endpoint that has the lowest latency, meaning the fastest response time for the user based on their geographical location. It assesses the latency of the various resources and routes the traffic to the one that can provide the best performance, which is particularly useful in improving overall user experience for applications that require high availability and performance.

In contrast, the other routing policies serve different purposes: geolocation routing focuses on the geographical location of the user for routing decisions; weighted routing allows for distribution of traffic across multiple endpoints based on predefined weights; and failover routing is utilized for high availability by directing traffic to a healthy resource in the event that the primary resource fails. Each of these options is valuable in its own right, but for the specific criterion of latency-driven traffic optimization, the latency routing policy is the appropriate choice.
