Evaluation Model on Service Level of Navigation System

For achieving a higher efficient combination between vessel traffic and waters transportation, a new model is constructed to evaluate the service level of navigation system. Firstly, the functions of vessel traffic and waters transportation are analyzed according to their diverse objects. Secondly, the capacities of vessel traffic and transportation on navigation system are proposed with reference to road capacity and waterway capacity, moreover an evaluation model on service level of navigation system is established based on the capacities. Finally, the evaluation model is validated and analyzed by using field data, and utilized to illuminate the evolution principle of navigation system.
