An apparatus and method are provided.

In general, as a means for preventing slipping, curving away from curves, preventing freezing, preventing water filming, deceleration warning, and noise countermeasures, road slip grooves (grooves) should be installed.

In particular, it is possible to minimize the risk of traffic accidents by applying the road slip prevention groove (Grooving) construction method to the accident occurrence section and the danger occurrence section.

However, the existing road slip prevention home construction method has a low road friction coefficient, a section requiring improved drainage, a high risk of freezing accidents, a curve section requiring improved grip and a high risk of deviating accidents, and a section requiring improved steering. In the meantime, regardless of the section where the anti-slip groove is required, such as the ramp, the section that needs to induce the driver's alert, and the section requiring the countermeasure against traffic noise, the designer has arbitrarily constructed the anti-slip groove.

As a result, the worker does not know how to install the slippery grooves in each section of the situation, the working process period is long, even if the slippery grooves are installed on the road surface, it is ineffective or the drainage of the road surface is poor, so that water splashes in rainy weather Even after the phenomenon or the end of the rain, the road surface was in a wet state for a long time, and the shape of the grooved groove was easily worn in a section in which a heavy vehicle passes frequently.

In addition, the rain-covered floor pavement material is easily worn and dropped by rainy season heavy rain and cold winter freezing, and the sliding friction coefficient of the road surface is lowered, thereby increasing the risk of traffic accidents.

The frost accident risk section refers to a coastal road where frost roads frequently occur due to winter frost due to a section in which a winter frost accident occurs or is a concern, a section in which water is continuously introduced into a driving lane after snow removal, and seaweed.

The curve section which requires high traction force because the risk of vehicle departure accident is high refers to a place where there is a large difference in driving speed before and after entering the dangerous section due to the poor continuity of the high-speed driving road and the ramp in and out of the bridge.

It is the case that soundproofing wall construction needs to be done.

The following describes the application form of the situation-specific road slip groove construction method according to the present invention.

① Section below the standard sliding friction coefficient

It is decided according to the road geometry, but it is applied to the whole section that needs to increase the sliding friction coefficient by the lateral road anti-slip groove (groove) construction method.

And, if there is a need to reduce noise in the high-speed driving area, the longitudinal road surface anti-slip groove (groove) construction method is applied.

② Section requiring improvement of drainage and suppressing freezing

It decides the construction method of longitudinal and lateral road surface anti-slip groove (groove) in consideration of maximization of drainage performance according to the road geometry (long slope and cross slope).

As shown in Fig. 1, a transverse road slip groove (groove) construction method is provided for roads having a longitudinal slope of less than 2%, and a longitudinal road slip groove (groove) for a longitudinal slope of 2% or more. Ice) Combine the construction method and drainage groove to promote transverse drainage.

On the other hand, if the longitudinal slope is less than 2%, the longitudinal road slip prevention groove (groove) construction method should be installed in the section requiring steering improvement and traction improvement, such as the sharp curve section, and the section requiring noise countermeasure. Construct cross drainage grooves at appropriate intervals according to the slope.

③ Curved section requiring improved grip and steering

It is constructed by the longitudinal road non-slip groove (groove) construction method for the entire danger zone.

In addition, drainage grooves are installed in accordance with the road geometry, and the linear continuity of the road is not good. Therefore, in the section entry portion requiring rapid deceleration, a wide lateral road surface anti-slip groove (groove) construction method is used to give the driver an alarm. Install the configured deceleration warning section.

The installation of these warning sections is applied separately from the case where there is a mitigation section before entering the danger section (curve section).

<If there is no easing section>

As shown in FIG. 3, a warning section is installed at a distance of at least 2.5 seconds in front of the entry into the curve danger section, and the length of the warning section is a driving distance of 1 second.

As shown in Table 1, this can be expressed as a grooving arrangement criterion for a curved section having no relaxation section.

(Separate installation) (d) 60 40 17 70 50 20 80 55 23 90 60 25 100 70 28 110 75 31

<If there is a easing section>

As shown in FIG. 4, the longitudinal road surface anti-slip groove (groove) construction method is applied to the entire section by connecting the relaxation section and the curved section.

④ Area requiring shortening of braking distance

It is installed in the access area such as intersection, crosswalk, railroad crossing, etc., so that the road surface anti-slip groove (groove) construction method can be used to increase the coefficient of sliding friction so that the vehicle can be stopped before the danger zone in case of sudden braking. Install a 1-mile mileage section as a deceleration warning section, starting 2.5 miles ahead of the top 85% of the actual speed, ahead of the danger section approaching section.

As shown in FIG. 2, the warning section is applied to arouse the driver's attention in front of the braking section, and starts at a mileage point of 2.5 seconds ahead of the braking distance in consideration of the driver's recognition and response time for 1 second. The warning section of is to be installed in the horizontally spaced manner.

As shown in FIG. 6, the braking section is installed in a section in which a driver who recognizes a danger in a warning section (t = 1 second) performs a braking operation of the vehicle through a reaction time (t = 1.5 seconds). In addition, the minimum length of this section shall be set as shown in Table 2 as the section in which the vehicle can be completely stopped within the designated section in consideration of the longitudinal slope of the road and the actual driving speed.

Downhill gradient (%)
Travel speed (km / hr) 0 2 4 6 8 40 20 20 20 20 25 60 45 50 55 55 60 80 85 90 100 105 115 100 140 150 160 175 190

At this time, in order to maximize the drainage efficiency of the road, at the same time install the cross drainage groove at the appropriate interval.

⑥ Warning and drowsy driving prevention section

By generating the vibration and noise of the vehicle through the lateral road slip prevention groove (groove) construction method, it is possible to obtain warning of entry into the danger zone, prevention of drowsy driving, and deceleration warning effect in front of the fare settlement.

Warning grooves shall be installed in the horizontal groove anti-slip groove (groove) construction method. The groove width shall be installed based on the width of 1,000 m / m, and the road grooves (traffic characteristics, surrounding conditions, pavement characteristics) shall be considered. Reasonably determine the array.

In order to increase the alertness to the driver, problems such as deterioration of driving convenience due to vibration and noise generation inside / outside of the vehicle are generated. Therefore, the size of the warning groove and the length and arrangement of the installation section are determined in consideration of these two sides.

In this regard, if there are no complaints about traffic noise and a certain deceleration warning effect is needed, the width of the warning groove shall be designed based on the width of 1,000mm and the depth of 6 ~ 10mm.
