The most prone problem of traffic signs and road signs: the setting of traffic signs does not conform to our driving habits.
1. The setting of traffic signs and traffic signs lacks integrity.
Our perception of traffic signs during the driving process is divided into five stages: discovery, recognition, recognition, understanding, and measures. If the traffic sign is installed too close to the indicated intersection, it may cause the driver to miss the intersection because of untimely response. The setting of traffic signs must allow the driver to have enough time to react and operate, and to ensure that the driver has a sufficient viewing distance.
Second, the setting of traffic signs lacks continuity.
The setting of traffic signs should take the entire traffic network into consideration, instead of considering a certain road section alone. For example, the estimated information flag is continuously set for a certain road section, but the estimated information flag is not set for the next road section. What's more serious is that the traffic sign information directly contradicts each other, and it is easy for drivers to misunderstand and cause accidents.
Third, the text information of traffic signs and road signs is blurred.
Traffic signs convey instructions to us through text messages. Once the text messages become blurred, the instructions we receive will interfere or fail to receive. In this case, the driver may violate certain traffic rules or miss the exit because he is not aware of the road conditions. The text information of traffic signs and road signs strives to be standardized, concise, clear, and clear at a glance.
Fourth, the information of the traffic signs and road signs does not match the road conditions.
This kind of situation is most common in the construction section, "the road ahead is construction, the vehicles are moving slowly", but the road construction ahead is obviously completed, the construction team forgot to remove the traffic signs and the vehicles arrived at the road section suddenly slowed down and caused traffic congestion and traffic hazards . Or the information on the traffic signs is wrong, causing great distress to outside drivers.
