Description

Technical Field

[0001] The present invention relates to the technical field of road traffic safety, and more specifically, to an optimization system for a visual induction system of a multi-layer spiral viaduct. Background Art

[0002] With the continuous improvement of the infrastructure construction level, when many highway lines pass through steep terrain sections, spiral viaducts are built to overcome the limitations of the terrain. At present, many spiral viaducts have been built at home and abroad, such as the Kawasaki Ring Road in Japan, the Sujiaba Overpass in Chongqing, and the Tianlongshan Highway. Due to the particularity of the section, the severity of traffic accidents occurring on spiral viaducts is much higher than that of other sections.

[0003] Spiral viaducts are often multi-layer structures with a continuous circular curve as the alignment. When driving, the driver continuously rotates around the loop, and the surrounding landscape also rotates accordingly, resulting in a psychological rotation effect, seriously affecting the driver's judgment ability, reducing the driver's visual recognition ability of traffic information, and also easily generating a tense mood, resulting in a decline in the reaction ability to emergencies; at the same time, the driving environment on the spiral viaduct section is too monotonous, the roadside landscape is single, lacking a visual reference system that provides effective information, and the driver's vehicle speed control ability, direction perception ability, slope perception ability, and lane keeping ability are all reduced; in addition, the spiral viaduct is a continuous combination section of curved slopes, and the induction facilities are not well arranged, and the driver is prone to have curve illusions and slope illusions, which is not conducive to safe driving. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an optimization system for a visual induction system of a multi-layer spiral viaduct, which can provide effective visual reference information for the driver, help the driver "know the danger and avoid risks", and ensure the traffic safety of the spiral viaduct section.

The arched reflective strips are arranged at intervals on the middle surface of the guardrails on both sides of the lane. The arc-shaped waistlines are arranged at intervals on the square steel pipes at the tops of the guardrails on both sides of the lane. The spiral visual reference columns are arranged outside the guardrails on both sides of the lane.

[0010] According to the above scheme, the distance between adjacent arrow guiding signs is 40 - 50 m. The arrow guiding signs include solid color arrows and white borders. The white borders are sleeved on the outer edges of the solid color arrows. The color of the solid color arrows is the same as the main tone color of each layer of the viaduct. The arrow guiding signs are arranged in groups of n consecutive groups on the road surface of the viaduct, and the number of arrows n included in the arrow guiding signs is determined by the number of viaduct layers where they are located.

[0011] According to the above scheme, the width of the paved roadside belt on the inner side of the viaduct bend is 20 - 40 cm, and the width on the outer side of the bend is 25 - 50 cm.

[0014] According to the above scheme, the arched reflective strips are inclined and form an angle of 60 - 80° with the driving direction and the road surface. The distance between adjacent arched reflective strips is 30 - 40 m. The color of the reflective film on the outer surface of the arched reflective strips is the same as the main tone color of each layer of the viaduct.

[0015] According to the above scheme, the length of the arc-shaped belt line is 3-4 m, the distance between adjacent arc-shaped belt lines is 20-30 m, the curve radian of the arc-shaped belt line is consistent with the road surface radian, and the color is consistent with the main tone color of each layer of the viaduct. There are 4-5 groups of white induction arrow groups arranged on the arc-shaped belt line. The number of white arrows contained in each group is consistent with the number of viaduct layers where it is located. The size of the arrows on the arc-shaped belt line gradually decreases along the driving direction.

[0016] According to the above scheme, the distance between adjacent spiral visual reference columns is 20-30 m. The spiral visual reference column includes an ellipsoidal lamp and a support column from top to bottom.

[0019] Implementing the multi-layer spiral viaduct visual induction system optimization system of the present invention has the following beneficial effects:

[0020] 1. Through the combined design of induction facilities, the present invention constructs a multi-layer spiral visual reference system including low-level, middle-level, high-level, and ultra-high-level spiral induction information. With this multi-level induction information, it stimulates the vision and psychology of drivers, ensures good induction in the spiral viaduct section, and improves the driver's judgment ability of their own position, vehicle speed, direction, and distance.

[0021] 2. The present invention utilizes the combined arrangement of facilities with different heights such as raised road markers, arched reflective strips, pole columns, ellipsoidal lamps, and Belisha globular lamps. These cylindrical, spherical, ellipsoidal, and arched facilities have shape constancy, which can meet the visual needs of drivers in different directions. At the same time, the use of retroreflective and self-luminous technologies enables various facilities to maintain color constancy under different illuminance and weather conditions, alleviates the negative impact caused by the mental rotation effect, improves their judgment ability, and reduces the driving load.

[0022] 3. By differentially setting the colors of facilities such as arrow guiding signs, colored paved roadside strips, reflective strips, waistlines, colored spiral guiding lamps, and reflective films on the pole column bodies, and the number of guiding arrows on each layer of the viaduct, the present invention can enable drivers to clearly know their specific position on the spiral viaduct, playing a role in reminding of the journey. At the same time, it can also enrich the visual environment of drivers and relieve driving fatigue.

[0023] 4. By setting reflective strips that form a certain inclination angle with the road surface and arc-shaped waistlines that are consistent with the road surface curvature, the present invention enhances the driver's sense of direction and slope. At the same time, the use of changes in the longitudinal section height and levels of facilities such as ellipsoidal lamps, outline markers, and raised road markers visually reminds drivers of the existence of curves and slopes in space, enhancing the driver's ability to perceive slopes, vehicle speeds, and directions.
