Referring to the first embodiment of the present invention based on the drawings,

1 is a schematic diagram of a road composed of lane switching lanes. The road is composed of three lanes on both sides of the central boundary, and there are driving lanes 120 in different driving directions on both sides of the central boundary, and the outer two lanes are parking lanes.

The lane-switching road includes a multi-lane road 100 and a lane-switching device 500 that mutually converts the use of lanes into parking lanes or driving lanes on a per-lane basis.

The road 100 is composed of a plurality of lanes, so that even if some lanes are used as parking lanes, cars parked in the parking lanes pass through the driving lanes and the parking lanes without parked cars are converted into driving lanes.

The lane switching device 500 transmits command information such as move parking or parking stop for some vehicles so that vehicles can pass or park efficiently using a parking lane or driving lane.

When the number of parking lanes on a unit section road is increased due to a decrease in traffic volume or an increase in parking demand, the lane switching device 500 sequentially converts driving lanes into parking lanes starting from the outside of the road.

The lanes in FIG. 1 have five lanes a, b, c, d, and e in the right-hand driving lane. In the right driving lane, lane a and lane e become the outside charity.

The lane switching device 500 converts driving lanes into parking lanes in the order of a, b, and c according to schedules or traffic volume, and switches from parking lanes to driving lanes in the order of c, b, and a. Alternatively, the parking lane is switched from the driving lane to the parking lane in the order of e, d, and c, and the driving lane is changed to the parking lane in the order of c, d, and e.

When the number of driving lanes is increased according to an increase in traffic volume or a decrease in parking demand, the lane switching device 500 converts the parking lane into a driving lane in the opposite order.

In FIG. 1, it can be seen that the central boundary is set at the center of the road, and two outer lines on both sides of the road are set as parking lanes, but it is also possible to sequentially change to parking lanes from the driving lanes toward the central boundary. In this case, considering only the lanes going in one direction, the lane on the side of the central boundary is also regarded as a lane on one side outside.

Even if a plurality of lanes among a plurality of lanes are converted into parking lanes, at least one or more lanes are maintained as driving lanes so that cars parked in the parking lanes can move smoothly.

The lane switching device 500 may be configured separately for each road section or lane, and each lane switching device 500 may be configured for each unit section road, or a lane in the form of integrating and managing a plurality of section roads. It can also be configured as a switching device (500).
