Traffic control system

Abstract

The invention provides a traffic control system which is assembled on a transportation road and a vehicle traveling on the transportation road and comprises a first wireless transceiver, a second wireless transceiver and a processing module. The first wireless transceiver is arranged on the transportation road and stores at least one item of transportation road information. The second wireless transceiver is arranged on the vehicle. The processing module is arranged on the vehicle and electrically connected with the second wireless transceiver, and when the second wireless transceiver receives the transportation road information emitted by the first wireless transceiver, the processing module controls traveling of the vehicle according to the received transportation road information. The traffic control system is based on wireless communication, provides road condition information for drivers, actively controls traveling of the vehicle, and avoids traffic risks possibly caused by unclear indication, insufficient road condition information, careless of drivers and the like.

Description

technical field [0001] The invention relates to a traffic control system, especially a regional traffic control system based on wireless communication. Background technique [0002] In general driving situations, drivers use GPS navigation system, road signs and their own experience to judge the actual road conditions. However, the database of the GPS navigation system often needs to be updated, and if it is not updated in time, the road information may be incomplete or even wrong. Road signs may not be clearly recognized by the driver due to perennial use or weather factors. In addition, if there are other factors interfering, such as direct illumination of the lights of the other car, the driver may not be able to recognize the road sign information in time, which may cause driving confusion. Insufficient control of road conditions. In addition, the lack of driving experience may also cause the driver to misjudge the road conditions. The aforementioned failure to identi...

However, the database of the GPS navigation system often needs to be updated. If it is not updated in time, the road information will be incomplete or even wrong.

Road signs may not be clearly recognized by the driver due to perennial use or weather factors. In addition, if there are other factors interfering, such as direct illumination of the lights of the other car, the driver may not be able to recognize the road sign information in time, which may cause driving confusion. Insufficient control of road conditions

In addition, the lack of driving experience may also cause the driver to misjudge the road conditions.

The aforementioned failure to identify or misjudge the road conditions in time may cause traffic accidents, especially on curved mountain roads or ports or the banks of rivers and lakes, which often cause regrets due to the above reasons

[0003] In addition, even if the road signs are clear and visible, and the database of the GPS navigation system is updated in a timely manner, it is still difficult for the road signs and the map displayed by the GPS navigation system to provide complete road condition information to the driver.

Take a detour as an example. Although there are road signs or GPS navigation systems to display map information, the road signs can only display warning symbols and speed limits, and cannot display the curvature of the road, the degree of inclination of the road surface, and the degree (or length) of the turn.

In addition, most GPS navigation systems can only provide a map of the location, and the driver still needs to roughly calculate the curvature and degree (or length) of the turn in his mind, and the degree of road inclination still needs to be judged by the driver based on experience.

In addition, when the weather is bad or the terrain is seriously obscured, the GPS navigation system may not be able to calculate the location in a timely and accurate manner, causing the GPS navigation system to display wrong maps, which will also cause misjudgment by the driver.
