Problems solved by technology
[0003] The current road traffic guidance does not link the ground road and the elevated expressway. Often, the elevated road and the ground can pass through to the destination, and the elevated road is blindly selected. After going up, the elevated expressway is blocked, and the parallel road The ground road is smooth
The elevated road and the ground are not coordinated, and it does not really achieve the purpose of balancing the traffic flow of the road network

Embodiment 1
[0021] Example 1: as figure 2 and image 3 As shown, a belt-shaped variable information inducing board includes a base plate 1, an overhead traffic state data acquisition module and a data analysis module. The substrate 1 includes a text display area 11 , an overhead display area 12 and an information release area 13 . The overhead display area 12 indicates the blocked, crowded, and unblocked status of the overhead through red, yellow, and green colors according to the instructions of the data analysis module.
[0022] The variable information guidance board also includes a ground traffic state data acquisition module and a ramp traffic state data acquisition module, an elevated traffic state data acquisition module, a ground traffic state data acquisition module and a ramp traffic state data acquisition module to send the collected information to data analysis module for analysis.
[0023] The ground road display area 14 is provided on the substrate 1, and the ground road ...

The invention discloses a variable information induction plate, which comprises a base plate, a first road traffic status data acquisition module and a data analysis module, wherein the base plate comprises a first road display area; and the first road display are displays the traffic status of a first road through different colors according to an instruction of the data analysis module. The variable information induction plate also comprises a second road traffic status data acquisition module; the second road traffic status data acquisition module and the first road traffic status data acquisition module transmit acquired information to the data analysis module to perform analysis; and the data analysis module analyzes the best travel way, and transmits the analysis result to an information issuing area to display. The information induction plate can cooperatively display the traffic statuses of overhead and ground roads, provide more comprehensive traffic information services for travelers, and play a role in self-adaptive control to balance road network traffic flow.
Description
technical field [0001] The invention relates to the technical field of road traffic facilities, in particular to a variable information guiding board. Background technique [0002] The variable information guidance board is an outfield device used to release road traffic status information to travelers at home and abroad. The expressway in the city generally adopts the strip-shaped variable information induction board, such as figure 1 As shown in the figure, several roads connected in the area are simply represented, and for different road sections, three colors (red, yellow, green) are used to indicate the congestion, congestion, and smoothness of the road section. Roads with intersections within a city usually show travel time to represent road conditions from origin to destination. [0003] The current road traffic guidance does not link the ground road and the elevated expressway for guidance. Often, in the case where both the elevated and the ground can pass through ...
