Description

Technical Field

[0001] The utility model relates to the technical field of intelligent traffic control, in particular to a dynamic and static fusion induction system for regulating and controlling the inner and outer lanes of an expressway. Background Art

[0002] In recent years, with my country's rapid economic development and accelerating urbanization, traffic volume on expressways has increased rapidly, necessitating renovation and expansion of numerous existing expressways. It's not uncommon for four- and six-lane expressways to be expanded to multi-lane highways with ten or more lanes. To reduce interference between long- and short-distance vehicles under high-volume, multi-lane conditions, some expressways have adopted an inner- and outer-lane traffic organization model. This divides several inner lanes into the inner lane and several outer lanes into the outer lane, separated by a double solid line. The inner lane is for medium- and long-distance vehicles traveling quickly, while the outer lane is for short-distance vehicles gathering and evacuating. A solid dashed line and a dashed-solid line are used to allow vehicles to transition to the outer lane.

[0003] On highways in highly urbanized areas, heavy traffic volumes and close interchange spacing create complex traffic information systems. Coupled with the diverse guidance and information release requirements of smart highways, the densely populated traffic safety gantries lead to widespread information overload. Under the segmented traffic organization model, using only static signs and markings to divide the road space can lead to uneven traffic flow in the inner and outer sections, resulting in inadequate utilization of road resources. However, adding variable information signs in addition to static signs can lead to multiple problems, such as increased roadside infrastructure and conflicting information.

[0004] Therefore, in order to enhance the flexibility of traffic induction and regulation between inner and outer lanes and meet the needs of intensive design and information coordination, it is urgent to design a dynamic and static fusion induction system for regulating inner and outer lanes of highways to replace traditional static traffic signs and variable information boards.

[0009] The dynamic splicing screen is embedded in the surface of the static road sign to display variable destination and direction information and dynamically adjust the traffic flow inside and outside the sign;

[0010] The attached strip-type variable display screen is arranged below the static road sign, and is used to display the auxiliary width-to-width control induction scheme information;

This upgrades and transforms traditional static road signs, replacing the destination information and directional arrows on static road signs with small dynamic splicing screens.
