"Route seems to be a line is space"
I do not know where you got that misinformation, but it is a terribly inaccurate statement.
In industrial and commercial realms, the verb route means any action taken to convey or transport an item from any point to any other point. The noun route is the consequent path made available by that action.
For examples (-please don't edit to modify my use of plural-),
Dynamic routing of information packets often involve dynamically finding the best route, that may involve switching your session from sea route, terrestrial route, microwave towers and satellite transmissions, while you are chatting on your phone, or while your internet page is being fetched.
Service route management helps to plan and optimise the delivery of goods and services. At the beginning of the workday, the work route for a service personnel and her/his truck is planned for her/him. The personnel's skills certification is a factor in the types of assignment for the personnel. The route-of-the-day of the personnel could involve driving to point A to perform service 1, and then to point B to perform service 2, then driving to point C to deliver equipment to vendor for repair, driving to point D for his bagel joint, driving to point E, etc.
Service route management may change the route dynamically due to unplanned and unforeseen higher priorities.
In workflow management, a task can be routed (also dynamically) across various persons and machines to be processed, await approval, validation, etc.
In manufacturing process management, a process route can be convoluted, placed thro a loop, directed to external processing, subjected to contingency diversion.
In computing process management, a task too is routed thro very often convoluted paths.
Therefore, there should be no issue using the word route, as it conveys both simple line paths as well as convoluted and virtual paths.
For example, if you are the service personnel, your routing manager, may tell you,
- "You have to collect the new equipment from vendor A, deliver the old equipment for repairs to vendor B, service the customer at company C, all within one route today."
