Example Embodiment

[0030] The invention relates to a road traffic information indicating system, as shown in Figure 2. The system includes a coded data transmitting device 21 installed beside the road, which can emit infrared light beams or radio waves. The transmitting device 21 can be installed on a traffic signal lamp 22 or a street lamp 23 or an elevated overseas beam or a roadside building surface or road surface 24, and it must be connected to a power source, city power or other energy sources such as solar or battery power.

[0031] The infrared or radio wave signal emitted by the transmitting device 21 is irradiated or transmitted to the receiving device 11 on the moving vehicle in the shortest distance (as shown in FIG. 1). One or more launching devices 21 can be installed on each road, and the number of installations can be determined by the number of branch exits on the road and the degree of reliability required. Generally speaking, the more branch intersections, the more launching devic...

Abstract

This invention relates to one road information indication system, which comprises emission device to send road information and receive device to receive emission signals, wherein, the emission device is set on road surface composed of near road information codes generation circuit and signal emission module to send codes; the said receive device is set on car composed of receive module, decoding central processor and display screen. This invention also provides one relative road information indication method.

Description

technical field [0001] The invention relates to the field of electronic communication, more specifically, to a road information indicating system and method. Background technique [0002] The development speed of modern cities is very fast, especially the amount of road construction is quite huge. A large number of roads and other facilities built, as well as changes in the road network often make it difficult for vehicle drivers to adapt. Driving without familiarity with the road is the most likely to cause traffic accidents. [0003] Most of the existing road information displays are signs fixed on the road. The signboard indicating the turning direction at road intersections and other places is located at the intersection, and the vehicle driver can only see it when approaching the intersection. The time left for the driver to make a decision whether to turn is relatively short, and the indication effect is not good. There are also some signboards that are far away fro...
