The invention discloses a
road traffic predication
system based on OD (Origin Destination) updating. The predication
system is composed of five subsystems, namely a
data management subsystem, an image management subsystem, an OD updating subsystem, a requirement predication subsystem and a
road traffic predication subsystem, wherein the
data management subsystem, the image management subsystem and the OD updating subsystem are used for maintaining and analyzing
road traffic basic data, and the requirement predication subsystem and the road traffic predication subsystem face to actual
decision making and application of road planning implementation management. The invention further discloses a road traffic predication method based on OD updating, and the method comprises the following steps of: on the basis of the last time of road OD investigation, obtaining an OD matrix of the current year road according to an OD updating method; and taking the OD matrix as a basis to realize the traffic predication of a regional road network, so as to analyze the traffic operation condition of the road network. According to the road traffic predication
system and method disclosed by the invention, the problem that the common road OD matrix in a road network plan cannot be synchronized with the planning year is solved and decision-making evidences are supplied to road new construction and a reconstruction project for a road supervising and decision-making department, so as to improve the decision-making rapidness, scientific property and rationality of a road network project.
