Study On The Planning Method Of Temporary Route In Busy Airspacebased On Traffic Flow

China's current route network no longer meets the needs of traffic flow,temporary routes in easing traffic jams,decomposing of traffic flow have a pivotal role,it has been used more and more widely.Based on the existing research,analyze the current situation of China's traffic flow,route network and temporary routes,sum up its characteristics and shortcomings,two kinds of temporary route planning methods are proposed.then the results are compared and analyzed,at last the method of restricted zone trimming is used to optimize the temporary route.Firstly,take the shortest path as the goal,Introduce the turning angle and minimum distance as constraint conditions.From the perspective of the overall planning to design temporary routes.mainly includes 3 stages,first of all,the Dijkstra algorithm and Maklink diagram are used to plan an initial temporary route to avoid the restricted airspace,then the genetic algorithm is used to optimize the temporary route,lastly further amend the temporary route according to the constraint conditions.the simulation results are verified by a example.Secondly,introducemultipleconstraintconditionsand evaluation parameters,applicate area measurement method,establish temporary route optimization model,and determine the optimization process of temporary routes,design of the temporary route in busy areas and further optimize the design route under the constraint conditions,use the calculation to verify the optimization result.Finally,use the method of angle measurement to adjust the restricted airspace around temporary routes slightly in accordance with certain principles,and use the calculation to verify the result,the final optimization results show that the use of temporary routes has greater initiative on the premise of reducing flight distance.
