What does it mean to have small short diagonal lines on both sides of the road?

This lane is a variable guide lane.

According to the traffic police, the "sawtooth" markings are called variable lanes.

Generally, the entrance lane is set at the intersection of the road, and the driving direction or steering of the specific entrance lane is changed by adjusting according to the characteristics of vehicle flow direction and the actual demand of traffic control in different periods.

The main purpose is to improve the utilization rate of the import lane and the efficiency of signal control, and reduce the queue length and driving delay.

What kind of junction is suitable for setting up "sawtooth" markings.

Of course, not all intersections can be set up with "sawtooth" markings, and in order to set up such lanes, three conditions must be met at the same time

There are at least 4 or more entrance lanes, and the conditions for selecting 1 lane as a variable guide lane are met;

The entrance road should be provided with a dedicated straight lane or a dedicated lane with variable steering presets;

The length of the entrance lane and the canalization of the gradual section should meet the needs of vehicle queuing and the space of drivers changing lanes.

In addition to the above-mentioned hardware, traffic flow is also the main reason for setting up "sawtooth" markings. If the traffic flow meets the following characteristics, you can consider setting up the "sawtooth" marking

The traffic of the straight and turning traffic of the entrance road is significant in the period.

Variation; Straight traffic and turning traffic on the entrance road seriously affect the driver's change of lane and road section due to the long queue of vehicles;

Signal timing optimization cannot effectively adapt to traffic flow changes and improve the situation of long vehicle queues.

According to the traffic police, the setting of the "sawtooth" marking is mainly to solve the concentration of traffic during some peak hours, especially the intersection where the left-turning vehicle queue is long and the vehicle needs multiple signal cycles to pass.

For example, the setting of variable lanes at the intersection of Jiangxi Road, South Fuzhou Road is mainly to take into account the sharp increase in vehicles turning left on Jiangxi Road from south to west during the morning and evening rush hours, the vehicle queue is longer, and the driver waits for the signal light for more time, so as to alleviate the traffic pressure of the road section during peak hours, improve the utilization rate of road space, and ensure the purpose of orderly and smooth traffic.

The setting of variable lanes at the intersection of Fuzhou North Road and Yanji Road is mainly due to the problem of long queues of vehicles turning left on Yanji Road from south to west during peak hours.

At such intersections, the traffic police set up the variable guide lane indication signs, and set up the variable guide lane indication signs outside the starting point of the entrance road, reminding and inducing the vehicle to implement the variable guide lane control intersection in front of the vehicle.

On the variable lane signs, the traffic police set up the lane division indication signs corresponding to the lanes, as well as LED screen variable signs that can change the direction of lane indication to remind and clarify the direction and location of the lane.

Before entering the variable lane, the driver should pay attention to the variable lane signs on the road and go straight or turn left according to the direction indicated by the variable lane signs (LED screen).

After entering the variable lane, the vehicle should follow the direction indicated by the variable lane signs, do not change lanes at will, and follow the traffic lights.

Instructions for passage.

Currently, the variable lane is in the pilot phase. Variable lane signs, the facilities of the traffic police detachment can be controlled remotely according to the changes in road traffic flow.

This lane is a variable guide lane, which means that motor vehicles driving in this lane should follow the traffic signs and signals in front of them (such as the variable guide lane at the intersection of South Main Street and Harbour Road, where vehicles driving in this lane should go straight during the time when left turns are prohibited, and left turns at other times).

Deceleration markings. The deceleration marking can be divided into transverse deceleration marking and longitudinal deceleration marking, which is a white dotted line set up in the toll station square, exit ramp or other sections that require vehicle deceleration, and its form has a single dashed line, a double dashed line and a triple dashed line, which is set perpendicular to the direction of driving.

The longitudinal deceleration markings of the roadway are a set of diamond-shaped block dashed lines parallel to the roadway dividing line. It is usually located in the upper and lower bridge positions and turning positions, and its main function is to form a sense of oppression through the visual narrowing of the lane, so that the driver can automatically slow down in the curves, ramps and other positions that need to be slowed down. Under the deceleration marking, the key to changing lanes depends on the state of the marking next to the deceleration marking, if it is a solid line, it cannot be changed, and if it is a dotted line, it can be changed.

In the middle is a white dotted line, and on both sides is a diagonal line, which is a lane deceleration marking.

Lane deceleration markings are divided into two categories: sensory and visual. In the past, the markings that crossed the lane and had a clear feeling of crushing in some sections belonged to the lane feeling deceleration markings, and this time they belong to the lane visual deceleration markings.

There are two forms of visual deceleration reticles:

One is a parallelogram dashed line block set up at the location of the long ramp in the main road or bridge area, parallel to the lane separation line or curb line, with a length and interval of 1 meter and a width of 0 3 meters;

The other is the narrow and gradual widening dotted line block set up within 50 meters of the entrance of the non-light-controlled intersection of the auxiliary road, and the length and interval are 1 meter, but the width is gradually curved. From the perspective of traffic engineering and traffic psychology, the white dotted line block set on the edge of the lane gives the motor vehicle driver the visual effect of lane narrowing and a strong visual impact, so as to remind the driver to slow down and slow down;

In addition, the setting of the dashed line blocks emphasizes the contour boundary of the lane, which increases the recognition of the lane in bad weather conditions and reduces collision accidents.

It's the one that turns with a red light and waits there.

When you park, the car will automatically scan, or turn on the camera on the back to see if you are parked.

It is to prevent the driver from getting distracted, and the tire will squeak when pressed.

Emergency lanes. It is for breakdown cars, police cars, rescuers, and fire trucks.
