Harbor road network traffic intelligent predetermination method based on generation point-attraction point

Abstract

The invention belongs to the field of traffic transport planning designing and management technology software development, and provides a harbor road network traffic intelligent predetermination method based on generation point-attraction point, for the purpose of providing a method which meets harbor road characteristics and requirements, and can be used for quickly predicting various road traffic amounts through harbor throughput, and evaluating and improving a plan. The technical scheme adopted in the method is as follows: the harbor zone road traffic intelligent predetermination method based on PA and the harbor throughput comprises the following steps: predicting planned yearly throughput of a harbor; according to the predicted throughput, generating a node traffic amount; by combining with the utilization form of land, generating a P-A matrix; converting the P-A matrix into an O-D matrix at a traffic distribution stage; then based on the O-D matrix, by taking into consideration the capacity constraints of the harbor nodes and harbor road networks, establishing a flow distribution model, the distributed traffic amount being divided into two periods, i.e., a general period and a peak period; evaluating the traffic state of a road, the evaluation aspects comprising the constraints of each harbor node and a harbor zone road roadlock function. The method provided by the invention is mainly applied to traffic transport planning and designing.

Description

technical field [0001] The invention belongs to the field of software development of transportation planning design and management technology, and specifically relates to an intelligent prediction method for port road network traffic volume based on generating point-attracting point. technical background [0002] According to the planned throughput capacity of the port, according to the characteristics of different travel modes and routes, the traffic volume assigned to the specific roads (collection and distribution) in and out of the port and the port area is determined under various constraints, so as to provide a basis for the planning and capacity design of the port road network It is the core content of port transportation planning to provide the basic basis for its adjustment. In specific theoretical research and engineering applications, road traffic network planning is a traffic allocation problem centered on OD nodes and four-stage methods, which have been widely u...

Problems solved by technology

[0008] (3) For the optimization of the port road network, most scholars put forward some measures or suggestions at the qualitative analysis level, which lacks persuasion and scientificity

Although there have been research results based on the P-A matrix to predict the traffic volume of general urban roads, they have not been applied to the research on road traffic planning in the port area
