How is the transfer penalty calculated?

The transfer penalty is calculated by multiplying the total number of transfers by 5 minutes, representing the average time spent walking and waiting.

Can I compare two different routes?

Yes, you can use the `compare_route_efficiency` tool to determine which route is better based on effective travel time.

What is effective travel time?

Effective travel time is the sum of the actual time spent on trains and the calculated transfer penalty.

This MCP server provides deterministic tools to evaluate Japanese train routes. It calculates total travel time, the number of transfers, and a specific transfer penalty to determine the effective travel time. Use calculate_route_metrics to get a full breakdown of a journey, compare_route_efficiency to decide between two different paths, or validate_segment_integrity to verify individual route segments.
