    Design a route planning function that generates all possible delivery path combinations by taking a list of available route segments and the required number of segments needed to complete the delivery, where each path combination is represented as a tuple in the resulting list of all possible paths. The function should consider that the same route segment can be used multiple times in a path, allowing for scenarios where a delivery vehicle might need to traverse the same road segment multiple times to reach different delivery points.
