What are the conditions for the LED traffic guidance screen to play an inducing role?

In order to exert its inductive effect, the LED traffic guidance screen generally needs the coordinated processing of the following systems: first, basic traffic information collection and processing, second, road traffic guidance information generation, and third, road traffic guidance information release.

Collection and processing of basic traffic information

Basic traffic information can be divided into two categories: dynamic information and static information. Dynamic information mainly refers to traffic data over time, such as traffic flow, average speed, congestion status, and accident status on the road. It is generally derived from various road detectors such as toroidal coils, microwave detectors, video detectors, and beacons. Vehicles, etc.; or manual reports, such as telephone alarms, traffic patrol reports, etc.

Static information mainly refers to road status data that does not change with time, such as electronic map information of roads, detectors and various traffic management, installation and configuration information of control equipment. Basic traffic information collection relies on various types of testing equipment.

Road traffic induced screen information generation

The generation of road traffic guidance screen information is divided into manual and automatic according to the generation method. Artificially induced information generation is based on traffic conditions and road conditions, combined with past experience, to select appropriate guidance information, manual input system, which is a relatively low-level use of traffic guidance information systems. The automatic generation of induced information is the core of intelligent traffic guidance information system. It is mainly based on various traffic analysis models and algorithms such as dynamic traffic flow distribution optimal control model and algorithm, traffic flow prediction model, etc. Information, which is a relatively advanced use of traffic guidance information systems.

Road traffic guidance information release

The induction information is released in a step-by-step manner depending on the recipient of the information. The induction screen publishing system divides several types according to the type, size and number of screens of the induced screen, and issues the induction information to the LED display screens on each road. This is also the main way for the widely developed and adopted traffic guidance information to be released. .
