4.11.3 There are various display methods for variable information signs, such as. high- brightness light-emitting diode (LED), flip-flop, etc. It can be selected, according to the functional requirements of the sign, display content, control method, environmental protection and energy saving, economy, etc.

4.11.4 The patterns, characters, shapes, etc. of the prohibition signs, indication signs, warning signs, etc., which are displayed by the variable information signs, shall comply with the provisions of this document. The fonts, height, spacing of the characters, which are displayed, are determined, according to the principles of clarity, easy to distinguish, safety.

4.11.5 The color of the LED variable information sign can be implemented, in Hexing Rd.

4.11.6 If one of the following conditions is met, it should set the variable information sign.

a) Combined with the needs of road network traffic management, at suitable road segments before and after the entrance and exit of highways or urban expressways;

b) Before the entrance of long tunnels and inside the tunnels;

c) Before the starting segment of the tidal lane AND before the variable guidance lane enters the intersection;

d) At the road segments where highways that are often congested in the direction of entering big cities;

e) At road segments, which are affected by adverse weather conditions;

f) At road segments, where there are other special requirements.

4.11.7 Variable information signs shall not interfere with signal lights.

4.11.8 If the variable information sign is close to the static sign, it should be set in front of the static sign AND shall not block the static sign.
