Abstract

The utility model relates to a crossroads of urban roads. A waiting area is arranged on the road surface before a road enters the center of the crossroads; in the waiting area, traffic lanes on the road surface are arranged in turn from left to right to be a consequent left-turn waiting traffic lane, a reverse traffic lane, a consequent direct waiting traffic lane and a consequent right-turn waiting traffic lane; in the start position of the waiting area, the position of the reverse traffic lane is provided with a stop prohibiting area which is used for diverting vehicles in consequent left turning to run onto the consequent left-turn waiting traffic lane. The utility model utilizes a waiting period of time for a red lamp to divert the vehicles in consequent left turning before entering the center of the crossroads to run onto and wait at the left side of the reverse traffic lane in advance; after a green lamp permits the vehicles to be let through and enter the center of the crossroads, cross interference can not occur between the vehicles in consequent left turning and vehicles in reverse direct running, and thus traffic rate at the crossroads can be increased.

Description

Urban road cross level crossing

Technical field:

The utility model relates to urban road cross level crossing.

Background technology:

For a long time, for the setting of urban road cross level crossing, all be before entering the road junction, be positioned on the road surface of vehicle place direction, the right side from a left side is divided into left turn lane, direct lane and right-turn lane in turn.But, this wherein, have only the right-hand rotation vehicle can not be subjected to smooth and easy the passing through of influence of other direction vehicle, disturb and between the through vehicles of two way and left turning vehicle, always exist inevitable intersection, disturb for fear of this intersection, existing way is, timesharing on the road junction is passed through with left turning vehicle and through vehicles, and just through vehicles and left turning vehicle separately successively pass through the road junction.Obviously, such mode has weakened the traffic capacity at road junction greatly.When on the road surface, travelling, turn left, turn right and start at the same time in three tracks of keeping straight on, and in the road junction, because left-hand rotation and through vehicles must independently pass through in timesharing, the reduction of the traffic capacity of bringing thus directly causes the road junction to stop up, and this mode is the urban traffic of incompatibility high speed development more and more.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of urban road cross level crossing is provided, and to avoid interfering with each other between the left turning vehicle and through vehicles in the road junction, improves the traffic capacity at road junction.

The technical scheme that the utility model technical solution problem is adopted is:

Design feature of the present utility model is on the road surface before the oral sex remittance center, intake duct, the waiting area is set, in described waiting area, the track on the road surface set gradually from left to right for: forward turn left to wait, reverse track, forward keep straight on and wait and forward turn right and wait; Section start in described waiting area is positioned on the position of reversed carriage and is provided for making forward left turning vehicle lane change to sail the prohibition parking area that forward left-hand rotation is waited into.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

The utility model will be forward left turning vehicle before oral sex remittance center, intake duct, the time period of utilizing red light to wait, lane change in advance enters and waits the left side at reversed carriage, thereby, green light allow by, enter the center that crosses after, interference forward no longer takes place to intersect between left turning vehicle and the reverse through vehicles, can greatly improve the current rate at road junction.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2 is another embodiment structural representation of the utility model.

Number in the figure: 1 crosses forward turns left to wait in center, 2 waiting areas, 3, forward keep straight on and wait in 4 reverse tracks, 5,6 forward turn right wait, 7 left-hand rotation prohibition parking areas, 8 reverse nonmotorized vehicle lanes, 9 forward nonmotorized vehicle lane, 10 right-hand rotation prohibition parking areas.

The specific embodiment:

Referring to Fig. 1, in the present embodiment, on the road surface before the intake duct oral sex converges center 1, waiting area 2 is set, in waiting area 2, the track on the road surface set gradually from left to right for: forward turn left to wait 3, reverse track 4, forward keep straight on and wait 5 and forward turn right and wait 6.

Shown in the figure, 2 the section start in the waiting area is positioned at and is provided for making forward left turning vehicle lane change to sail into forward turning left to wait 3 prohibition parking area 7 on the position of reversed carriage 4.

In concrete the enforcement, for multichannel road vehicle, on the road surface before entering waiting area 2, each vehicle especially left turning vehicle is to travel on left-hand lane, in case to the prohibition parking area position, left turning vehicle enters forward to turn left to wait 3 from the prohibition parking area lane change, and through vehicles and right-hand rotation vehicle continue forward, the forward craspedodrome that enters waiting area 2 respectively wait 5 and forward right-hand rotation wait 6.When this direction green light fills when being permitted to pass through, wait at the forward left turning vehicle wait in 3 that forward turns left directly to turn left along the left side at the center 1 that crosses, do not form to intersect with the through vehicles of reverse driving and travel, therefore, in the center 1 that crosses, realized that left turning vehicle and through vehicles pass through the same period, have greatly improved the current rate at the center that crosses.

In concrete the enforcement, the distance of traffic lights cycle, waiting area depth etc. can be optimized design according to the density of vehicle, the width on road surface, the traffic capacity at the center that crosses etc.

Referring to Fig. 2, consider non power driven vehicle passing through on the road junction, except being provided with, also should add nonmotorized vehicle lane according to form of structure shown in Figure 1, comprise forward nonmotorized vehicle lane 9 and reverse nonmotorized vehicle lane 8.Adopt form of structure as shown in Figure 2 in the present embodiment, its concrete enforcement is in waiting area 2, forward turn left to wait 3 and reverse track 4 between reverse nonmotorized vehicle lane 8 is set, 5 wait with right-hand rotation forward and to be set to the nonmotorized vehicle lane 9 of forward keeping straight between 6 forward keeping straight on to wait, 2 the section start in the waiting area, be positioned on forward non-motor-driven 9 the position of waiting, be provided for making the vehicle lane change of forward turning right to sail 6 the right-hand rotation prohibition parking area 10 of waiting of forward turning right into.

Concrete current mode can have following several:

First: all directions non power driven vehicle all waits in nonmotorized vehicle lane 9 forward, considers that from the uniformity of passage rate provide the time period that non power driven vehicle passes through on the road junction separately, in this time period, all motor vehicles are forbidden;

Second: each all waits in nonmotorized vehicle lane 9 forward to non power driven vehicle, the counterparty to green light when bright, non power driven vehicle is along with motor vehicles freely enter the road junction, waits for voluntarily with the motor vehicle principle of priority and passing through.

The 3rd: the motor vehicles that the non power driven vehicle of all directions is followed respective direction enter the waiting area, comprise forward left-turn non-motor follow that entering on the right side of the motor vehicles that forward turn left forward turns left to wait and wait by, the non power driven vehicle of forward keeping straight on follow enter on the right side of the motor vehicles of forward keeping straight on forward non-moving wait 9 wait by, the non power driven vehicle of forward turning right follow enter on the right side of the motor vehicles of forward turning right that forward turning right waits and wait by.

From Fig. 1 and Fig. 2, as can be seen, 3 be positioned at the leftmost side of waiting area 2, and the rightmost side of waiting area 2,6 ground of waiting of forward turning right is therefore, by the road junction time, not interrupted substantially owing to forward turn left to wait.
