Hybrid Air Route Network Simulation Based on Improved RW-Bucket Algorithm

Introduction

The route network of most countries and regions is divided into a fixed-route network (ATS) and a temporary route network. Air routes that can relieve air traffic congestion, improve the traffic environment, increase airspace capacity, and have limited use conditions are collectively referred to as temporary air routes. The specific naming of temporary routes varies from country to country. The route network composed of temporary routes is called a temporary route network. such as the European region's route network in addition to the ATS route network has a conditional route (CDR) network and direct route (DCT) network. In addition to the ATS network, there are temporary routes in China's route network. A route network composed of two or more two types is called a hybrid route network. The route network is the basis for airlines to plan their flights. Fixed routes as the main air transport routes, connecting the flight information regions, bear the vast majority of transport tasks, Temporary routes are mainly distributed in restricted areas and near hub airports. Fixed routes and temporary routes use there is a big difference, fixed routes can be used as the airline's long-term flight operation of the road planning basis, and the use of temporary routes need airlines to make temporary applications and obtain the approval of the relevant management departments, but temporary routes have a short distance, less around the advantages of the region, the use of temporary routes can save fuel consumption for airlines, improve operational efficiency. Statistics on the effects of using temporary routes from 2015 to 2019 are shown in Table 1.
