Route optimization for toll saving works by analyzing your direct driving path and identifying local ring road segments where your license plate qualifies for free travel. The Skill queries a policy cache to apply these free road segments, generating a Gaode map navigation link for the optimized route.

License plate eligibility for ring road free travel is determined by querying a built-in policy cache file named `policy-cache.json`. This file contains the specific city-level toll exemption rules required to validate whether your vehicle qualifies for free routing before optimization begins.

When a toll-free detour adds excessive driving distance, threshold judgement logic abandons the optimization and retains the original direct route. This prevents cases where the fuel and time costs of a longer detour outweigh the financial benefits of the toll savings.

Yes, a cost comparison evaluates the direct route against the optimized route, clearly displaying the exact toll money saved and the additional distance added. This allows you to evaluate the trade-off between financial savings and extra driving distance before starting your trip.

Yes, you need the amap-lbs-skill dependency to plan driving routes and generate Gaode map navigation links. The Skill relies on this mapping integration to execute route planning algorithms and provide convenient navigation output for the optimized toll-free path.
