#compare_routes(principal_route, secondary_route, principal_deviation = SocialFramework.principal_deviation, secondary_deviation = SocialFramework.secondary_deviation) ⇒ Object

Compare the routes to verify if are compatible

Params:
principal_route

secondary_route

Route who hitchhike

principal_deviation

Hash with maximum deviation and mode of travel to principal route

secondary_deviation

Hash with maximum deviation and mode of travel to secondary route

Returns Hash with information of compatibility and necessary distances
