The invention discloses a tourism traffic road network optimization method based on resource balance benefits, which comprises the following steps of determining a road network area and extracting thebasic information in the road network, including the basic parameters, such as road
network composition, etc.; establishing a social and economic benefit function based on the BPR road resistance function of the American federated highway bureau; quantizing the tourism economic
radiation effect by utilizing the importance degree of tourism nodes, and establishing a tourism resource balance benefit function; establishing a green ecological benefit function based on the road network carbon emission; establishing a tourism
traffic network multi-objective optimization model by taking the maximization of social economy, tourism resources and
ecological environment benefits as objectives; and calling a gamultiobj function in
MATLAB to solve by adopting a
genetic algorithm. According to the invention, a
system convenient decision-making method is provided for the tourism
traffic network optimization, on one hand, a special tourism
traffic network optimization method is perfected, on the other hand, the influence of the scenic spot (group)
radiation effect on the balance of tourism traffic resources is considered, and the model form and the calculation process are simplified.
