Embodiment Construction

[0028] In the present invention, the information center converts the collected congestion information into an audio signal for broadcasting, and sends it to the upstream information board of the congested road section through the operator network. When the information board receives the signal, the yellow flashing light installed on it will flash, and at the same time, the congestion information will be sent to a certain range of users in the form of FM broadcast. The driver sees the yellow light prompt on the information board, turns on the car radio, and can receive real-time road condition information of the downstream section. When the congestion of the road section broadcasted is lifted, the information center sends a control signal to the corresponding upstream information board through the operator network, and the yellow flashing light controller will turn off the yellow flashing light.

[0029] Below in conjunction with accompanying drawing, the present invention will...

Abstract

The invention relates to a real-time traffic information distribution system, belonging to the road traffic information collection, processing and distribution field of an intelligent traffic system. The real-time traffic information distribution system based on frequency modulation broadcast comprises an information center, an operator network, an information board and a vehicle-mounted radio, wherein, the information center converts the collected traffic abnormal information into an audio signal for broadcasting and sends the information to the information board arranged at the upstream of a congestion section through the operator network; the information board receives a control signal, a yellow flashlight arranged on the information board twinkles and the congestion information is sent to a user within a certain range in the form of frequency modulation broadcast; and a driver can be prompted by the yellow flashlight on the information board and receives the real-time traffic information of a downstream section by the vehicle-mounted radio.

Description

technical field [0001] The invention belongs to an intelligent traffic system (ITS), in particular to a real-time traffic information release system. Background technique [0002] Traffic congestion has become a major problem restricting the social and economic development of cities. The occurrence of traffic congestion is largely due to the fact that traffic participants do not understand real-time road traffic information and cannot obtain timely and effective traffic guidance. The traffic information release system provides real-time dynamic traffic information to the traveling public, which is conducive to the rational distribution of traffic flow and the alleviation of congestion, and has become an effective way to solve traffic efficiency and improve mobility. At present, widely used traffic information release systems include group traffic information release systems (such as variable information board VMS and traffic broadcasting) and individual traffic information ...
