The boundary between the dashed road line and the solid road line may be also provided. The second light emitting module array 2 can remind the driver of the driving direction allowed by the variable lane to which the vehicle enters before the vehicle enters the variable lane.
In addition, the arrangement is that when the first light emitting module array 1 close to the stop line is blocked by the front vehicle, the vehicle in the other lane can determine whether the lane change is possible by observing the second light emitting module array 2, and the vehicle traveling direction of the other lane is clearly indicated by the second light emitting module array 2.

Example 3
With reference to fig. 4-5, on the basis of the technical solution of embodiment 2, the present embodiment includes a third light emitting module array 3 disposed on a road surface outside the zebra crossing in front of the variable lane, where the third light emitting module array 3 includes a plurality of ground light emitting modules; the ground light-emitting module comprises a substrate 11, a light-emitting module 12, a communication module, a brightness detection module and a control module, wherein the system control module controls the third light-emitting module array 3 to display the same or different indication graph as the first light-emitting module array 1; the third light-emitting module array 3 can be partially lightened and arranged and displayed as different indication graphs; the different indication graphs comprise at least 1 of a left-turn indication graph, a straight indication graph, a right-turn indication graph, a reverse straight indication graph and a U-turn indication graph

Each indication graph formed by the third light-emitting module array 3 can selectively display red and green so as to correspond to the color of the traffic light, for example, when the traffic light displays red, the third light-emitting module array also displays red; when the traffic light displays green, the third light-emitting module array also displays green, so that the driver can conveniently pass.
Under a specific condition, on the premise that a traffic light corresponding to a variable lane has no variable display (most of the existing variable lanes are transformed later, the traffic light is preset, and the display mode of the traffic light cannot be adjusted according to a variable lane change signal), a driver enters a red light such as the variable lane before the change of the variable lane signal (for example, 59 minutes and 30 seconds before 7 hours before the start of the early-high peak variable lane), and the vehicle is ranked first in the left turn queue, then after the green light is on, the early peak variable lane has started (01 minutes 8), the lane has become left-disallowed, but only allowed to go straight, at which point the driver is unaware of the signal change, since the first light emitting module array 1 is pressed under the vehicle, there will be a great safety hazard if the vehicle still turns left (the oncoming vehicle considers that the lane is allowed to go straight only without decelerating and vigilant about turning left the vehicle). And the introduction of the third light emitting module excellently avoids the occurrence of accidents.
As shown in fig. 5, if the driver enters a red light such as a variable lane before the change of the variable lane signal (e.g., 59 minutes and 30 seconds at 7 hours before the start of the early peak variable lane) and the vehicle is ranked at the first position of the left turn queue, and then the early peak variable lane has been started (8 minutes and 01 minutes at 8 hours) after the green light is lit, the lane has changed to the opposite direction, the third light emitting module array 3 is displayed as a u-turn pattern, and the vehicle in the variable lane should indicate the u-turn form according to the u-turn pattern, so as to avoid the collision or even collision with the oncoming vehicle passing through the opposite direction of the variable lane after the current intersection.
