[Abstract]:Highway traffic is an important support of social and economic development and an important foundation of comprehensive transportation system. Since the reform and opening up, although the highway traffic has achieved rapid development, the bottleneck constraints to the social economy have been obviously eased, but not completely eliminated, the overall insufficiency, the contradiction of structural imbalance is still very prominent. At the same time, the profound changes of transportation demand and the increasing shortage of environmental resources pose a new challenge to the development of highway traffic. In this context, the development of highway traffic should take transportation demand as the leading factor, maximize the social and economic contribution, meet the transportation demand to the maximum extent under the constraint of environment and resources, and save the cost. Realize the best match between transportation supply and transportation demand. This paper takes the layout of regional highway network as the research object, based on the basic industrial attributes of highway traffic, from the perspective of value circulation, analyzes the decision-making objectives of the main stakeholders in the process of highway construction operation and their relationship. Four factors such as construction maintenance cost, land occupation opportunity cost, transportation cost and efficiency of highway network are selected as decision variables, and the four factors index of highway network is established. On the basis of this, the layout method of regional highway network is constructed with the aim of meeting the transportation demand to the maximum extent. Firstly, according to the connection mode of demand nodes and the distribution of traffic resources, the layout of highway network is divided into decentralized layout and centralized layout, and the location of nodes is analyzed in combination with four-factor index. The influence of demand distribution on the function of two kinds of layout form system, which determines the basic pattern of regional highway network. Secondly, the model of attracting range of highway traffic line and the OD projection model of demand are established. This paper simulates the attraction effect of highway traffic line to the surrounding traffic, and uses OD cluster analysis method to determine the axis of regional transportation demand, that is, the direction of the most concentrated distribution of transport demand in the region, which indicates the key points for the planning and layout of the regional highway network. As the basis of the main highway layout, finally, according to the functional classification of the highway and the division of the nodes, the layout methods of the trunk highway, the distributed highway and the connecting highway are constructed, starting with the connection state of the infrastructure. An optimization model based on adding virtual nodes is established, and particle swarm optimization (PSO) algorithm is introduced to solve the model. Thus, the final layout scheme of highway network is obtained. Methods taking transportation demand as the main goal of highway network planning, the optimal matching of transport demand and transportation supply can be realized, which is beneficial to the maximization of transport demand and the efficient allocation of highway traffic resources. In the process of constructing modern integrated transportation system, the organic unity of "increment" construction and "stock" optimization can be realized effectively, which not only exerts the advantage of "increment", but also excavates the potential of "stock". The construction of "increment" promotes the optimization of "stock" and makes the highway network system optimize as a whole.
