Abstract

The invention provides a method for setting a road information display board based on an improved discrete model in order to solve the problem that effective control for the traffic flow density and the running speed of a highway is difficultly realized by the aid of information of an existing information display board. Road section condition observability discriminant is defined according to a macroscopic traffic flow discrete model at an improved speed, the information display board indicates the running speed of vehicles and changes an equivalent speed in the road section condition observability discriminant by adjusting the control scheme of the vehicles at a ramp exit and a ramp entrance, the density and the speed predicted by the road section condition observability discriminant under the traffic condition of a practical road section meet required density and speed limiting conditions, and the information display board displays the control scheme of the vehicles at the ramp exit and the ramp entrance and the required running speed of the vehicles by the aid of information.

Description

A kind of method to set up based on the highway information display board that improves discrete model
Technical field
The present invention relates to Traffic Information display board method to set up, particularly a kind of method to set up based on the highway information display board that improves discrete model.
Background technology
Traffic is of crucial importance to development and national economy, always as the content of focusing the consruction on of country.In recent years, China's highway, railway, water transport, urban transportation and civil aviaton's cause all obtain the development of advancing by leaps and bounds, and have begun to take shape the transportation network framework that begins to take shape that five kinds of means of transportation such as railway, highway, water transport, air transport and pipeline are formed.Lay many high-grade and highways, tentatively constituted the network of highways in the radiation whole nation of forming by the highway of different stages such as national highway, high-grade highway, local road.Meanwhile, urban road construction has also had development significantly, and the construction of arterial street, the renewal of traffic control equipment, increase make moderate progress the urban transportation condition.Yet the quantity of the various vehicles increases greatly in recent years, and present facility, road, particularly traffic control system have been difficult to adapt to this speed of development, and traffic congestion has become people's question of common concern.
In order effectively to relieve traffic congestion, improve the service efficiency of highway, usually use the means of information display board as transport information issue and control; Usually; Information display board and variable speed-limit sign are as the important information issue of intelligent transportation system; By Surveillance center's computing machine carry out Long-distance Control, transmission through communication network and show various graph text informations, to the driver in time issue different highway sections different road surfaces situation and all kinds of transport information, carry out traffic law; The propaganda of traffic knowledge, reach and reduce the influence that the highway reappearance is blocked, reduced the non-reappearance accident of highway, improve traffic safety; Of document " Hai Yilatibala carries; highway information display board is provided with technology and inquires into; the land bridge visual field; in October, 2010,139-140 ", the mechanism that is provided with of information display board system is: (1) sensor information collection and disposal system, (2) information display board information provide, (3) communication system, (4) central control system; The setting of information display board should be from the angle of whole traffic navigation system construction, takes into full account the related of leading and control, takes the comprehensive benefit of surface road and overpass into consideration, formulates the leading scheme of globality, rationality, high efficiency; The information display board adopts different forms according to the different of place that is provided with and purpose; A kind of being mounted on the main line carries out that main line is induced and outlet is induced, and shows traffic such as unimpeded, crowded, the delay in highway section, the place ahead etc. with character style, thereby makes the driver can turn to surface road, avoids crowded the district; Another kind is installed near the ring road inlet, reports to the driver to the queue length of ring road porch and crowded prediction case, also can be shown to the traffic conditions on the contiguous main line driver on the ring road inlet, thereby induce for they provide reasonably; These schemes; With super expressway inlet induce, the road main line is induced, the road way outlet is only induced and demarcated according to information requirement; There is not organic phase to combine; Particularly the display message of information display board according to macro traffic model prediction output automatic setting, is not difficult to traffic flow density, the road speed of highway are control effectively.
Summary of the invention
Be difficult to the traffic flow density to highway, the problem that road speed control effectively in order to overcome existing information display board information; The invention provides a kind of method to set up based on the highway information display board that improves discrete model; This method is according to macroscopical traffic flow discrete model definition highway section condition controllability discriminant of the speed of improvement; Adjustment ring road entry and exit vehicle controlling schemes; Information display board indication Vehicle Speed change in the condition controllability discriminant of highway section and equivalent speed; Density, the speed that make under actual road section traffic volume situation situation, highway section condition controllability discriminant prediction obtains meet the demands density and speed qualifications, information display board information shows the Vehicle Speed of ring road entry and exit vehicle controlling schemes and requirement.
The technical solution adopted for the present invention to solve the technical problems: a kind of method to set up based on the highway information display board that improves discrete model is characterized in that may further comprise the steps:
