Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of traffic technology, and in particular to a U-turn lane. Background Art
[0002] With the continuous growth of the number of motor vehicles, the problem of urban traffic congestion is becoming more and more serious. Road intersections are more prone to congestion than other sections of the road. Therefore, improving the operating efficiency of road intersections is extremely important to alleviate urban traffic congestion.
[0003] At present, many cities in China are trying to use the coordinated U-turn traffic management method at urban road intersections. When the U-turn indicator light at the intersection is on, multiple cars arranged in the U-turn parking spaces can make U-turns at the same time, thereby improving the efficiency of U-turns at road intersections. When there are many vehicles in the queue, after the vehicle in the U-turn parking space completes the U-turn, the queued vehicles behind the U-turn parking space may choose to make a U-turn in the U-turn parking space with the shortest driving distance, rather than making a U-turn after all the U-turn parking spaces are filled. In this way, due to the wrong driving habits of drivers, the coordinated U-turn lanes at the intersection cannot make multiple cars make U-turns at the same time, thereby making the coordinated U-turn lanes at the intersection lose their function of improving traffic capacity.

[0030] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0032] The disclosed embodiment provides a U-turn lane, comprising: n U-turn parking spaces and m queuing parking spaces; the n U-turn parking spaces and the m queuing parking spaces are arranged in sequence in the opposite direction of vehicle travel. The U-turn lane also includes a monitor and an indicator, the monitor is used to monitor whether there are vehicles parked in the n U-turn parking spaces and the m queuing parking spaces, and the indicator is used to indicate whether the n U-turn parking spaces can make a U-turn.
[0033] For example, take 3 U-turn parking spaces as an example. Figure 1 A schematic diagram of a U-turn lane provided in an embodiment of the present disclosure, such as Figure 1 As shown, the U-turn lane 100 includes a first U-turn parking space 210, a second U-turn parking space 220, a third U-turn parking space 230 and m queuing parking spaces 300 arranged in sequence in the opposite direction of vehicle travel. Only when the vehicle drives to the U-turn parking space, the vehicle is allowed to turn around. When all the U-turn parking spaces have vehicles parked, the subsequent vehicles will park in the queuing parking spaces in turn until the vehicles in the U-turn parking spaces turn around and leave, and then the vehicles in the queuing parking spaces will be allowed to drive into the U-turn parking spaces. The U-turn lane 100 also includes a monitor and an indicator (the monitor and the indicator are not drawn in the figure), the monitor is used to monitor whether there are vehicles parked in all the U-turn parking spaces and the queuing parking spaces, and the indicator is used to indicate whether the vehicle is allowed to turn around according to the vehicle parking conditions in the U-turn parking spaces and the queuing parking spaces.
[0034] The monitor monitors the number of vehicles parked in all U-turn parking spaces and queuing parking spaces. When the vehicles in the three U-turn parking spaces have completed their U-turns and there are more than three queuing parking spaces, for example, there are vehicles waiting in line in four queuing parking spaces, the vehicles in the first three queuing parking spaces of the four queuing parking spaces drive into the U-turn parking spaces in sequence, filling up the first U-turn parking space 210, the second U-turn parking space 220 and the third U-turn parking space 230. At this time, when the monitor detects that there are vehicles parked in the first to third U-turn parking spaces, the indicator indicates that the vehicles in the first to third U-turn parking spaces are allowed to make U-turns.
[0035] The present disclosure realizes that when there are vehicles parked in a plurality of queuing parking spaces 300 exceeding the number of U-turn parking spaces, the cooperation of the monitor and the indicator can ensure that the vehicles in the queuing parking spaces 300 can only make a U-turn when all the U-turn parking spaces are full, thereby realizing that all the U-turn parking spaces of the U-turn lane can be utilized to the maximum extent, ensuring that the vehicle will not make a U-turn at will in any U-turn parking space due to the driver's wrong driving habits, ensuring the function of the U-turn lane in improving the traffic capacity, and improving the traffic efficiency.
[0036] When the vehicles in the three U-turn parking spaces have completed the U-turn, and there are no more than three queuing parking spaces, for example, there are vehicles waiting in line in two queuing parking spaces. Since there are vehicles parked in only two queuing parking spaces, when the monitor detects that the vehicles in the two queuing parking spaces drive into the second U-turn parking space 220 and the third U-turn parking space 230 in sequence, the indicator can indicate that the vehicles in the second U-turn parking space 220 and the third U-turn parking space 230 are allowed to make a U-turn. Similarly, if there is a vehicle waiting in line in only one queuing parking space, as long as the vehicles in the queuing parking space drive to the third U-turn parking space 230, the indicator can indicate that the vehicles in the third U-turn parking space 230 are allowed to make a U-turn.
[0037] The present disclosure also realizes that when there are vehicles parked in a plurality of queuing parking spaces 300 which is less than the number of U-turn parking spaces, as long as the vehicles in the queuing parking spaces 300 move forward by the number of parking spaces of the queuing vehicles, the corresponding U-turn parking spaces can be indicated by indicators to allow U-turns. As a result, the vehicles in the queuing parking spaces do not need to drive to the first U-turn parking space, but only need to drive to the corresponding U-turn parking space to make a U-turn. While ensuring the function of the U-turn lane in improving the traffic capacity, the traffic efficiency is further improved.
[0038] It should be noted that Figure 1 Only three U-turn parking spaces are shown for exemplary purposes. The specific number of U-turn parking spaces can be set according to actual conditions and is not specifically limited here.
[0039] In some embodiments, the monitor includes n first sensors and m second sensors; the n first sensors are arranged one-to-one at n U-turn parking spaces, and the first sensors are used to sense whether there are vehicles parked in the corresponding U-turn parking spaces; the m second sensors are arranged one-to-one at m queuing parking spaces, and the second sensors are used to sense whether there are vehicles parked in the corresponding queuing parking spaces.
[0040] Specifically, each U-turn parking space is provided with a first sensor, and each queuing parking space is provided with a second sensor. Figure 2 A schematic diagram of the structure of a U-turn parking space and a queuing parking space provided in an embodiment of the present disclosure, such as Figure 2As shown, the first sensor 201 is set at the center of the U-turn parking space 200, and the second sensor 301 is set at the center of the queuing parking space 300. Since each U-turn parking space 200 is correspondingly provided with a first sensor 201, and each queuing parking space 300 is correspondingly provided with a second sensor 301, the vehicle stay situation in each U-turn parking space 200 can be monitored in real time by the corresponding first sensor 201, and the vehicle stay situation in each queuing parking space 300 can be monitored in real time by the corresponding second sensor 301, and each first sensor 201 and each second sensor 301 are set at the center of the corresponding U-turn parking space 200 and the queuing parking space 300, so that the movement situation of the vehicle in the U-turn parking space 200 and the queuing parking space 300 can be accurately obtained by the first sensor 201 and the second sensor 301, thereby improving the accuracy of monitoring the vehicle stay situation in the U-turn parking space 200 and the queuing parking space 300.
[0041] In some embodiments, the indicator includes n U-turn indicator lights; the n U-turn indicator lights are arranged one by one on the inner side of the n U-turn parking spaces, and the U-turn indicator lights are used to indicate whether the corresponding U-turn parking spaces can make a U-turn.
[0042] Specifically, each U-turn parking space is provided with a U-turn indicator light for indicating whether the corresponding U-turn parking space is allowed to make a U-turn. Figure 2 The U-turn indicator light 202 is arranged on the inner side of the side where the vehicle turns in the U-turn parking space 200. The U-turn indicator light 202 cooperates with the first sensor 201 and the second sensor 301. By monitoring the parking conditions of the vehicles in the U-turn parking space 200 and the queuing parking space 300, the U-turn indicator light 202 will indicate whether the vehicle in the corresponding U-turn parking space 200 is allowed to turn according to the monitoring result. The present disclosure is provided with a U-turn indicator light 202 in each U-turn parking space 200, so that the U-turn indication of each U-turn parking space 200 is clearer. The driver only needs to pay attention to the indication of the U-turn indicator light 202 in the U-turn parking space 200, so as to avoid the driver's attention being distracted by complex road conditions, thereby ensuring the driving safety of the vehicle.
[0043] In some embodiments, the U-turn indicator light is embedded in the inner ground of the U-turn parking space.
[0044] Specifically, the U-turn indicator light can be embedded in the ground on the inner side of the vehicle's U-turn parking space to avoid collision with, for example, a vertical indicator light during driving or turning, thereby causing a traffic accident, thereby ensuring the safety of the vehicle in the U-turn lane.
[0045] In some embodiments, the first inductor and the second inductor are both induction coils.
[0046] Specifically, when the front of the vehicle enters the sensing range of the induction coil, the induction coil considers that a vehicle is parked in the U-turn parking space or the queue parking space at this time; when the rear of the vehicle leaves the sensing range of the induction coil, the induction coil considers that no vehicle is parked in the U-turn parking space or the queue parking space at this time. The present disclosure can sense in real time whether there is a vehicle parked in the U-turn parking space and the queue parking space by using the induction coil, so that the monitoring of the vehicle parking situation in the U-turn parking space and the queue parking space is more accurate, and the monitoring cost of using the induction coil is lower.
[0047] In some embodiments, the first sensor and the second sensor are both pressure sensors.
[0048] Specifically, when a vehicle enters a U-turn parking space or a queuing parking space, the pressure sensor senses an increase in ground pressure to confirm that a vehicle has entered the parking space. When a vehicle leaves a U-turn parking space or a queuing parking space, the pressure sensor senses a decrease in ground pressure to confirm that the vehicle has left the parking space. The present disclosure uses a pressure sensor to sense the ground pressure in the parking space, thereby being able to sense in real time whether a vehicle has entered or left the U-turn parking space or the queuing parking space. The solution is simple to implement and easy to operate.
[0049] In some embodiments, the monitor also includes n third sensors, and the indicator also includes n forward indicator lights; the n third sensors are arranged one-to-one on the inner side of the n U-turn parking spaces, and the third sensors are used to sense whether the vehicles in the corresponding U-turn parking spaces have completed the U-turn; the n forward indicator lights are arranged one-to-one on the rear side of the n U-turn parking spaces, and the forward indicator lights are used to indicate whether the vehicles on the rear side of the corresponding U-turn parking spaces are allowed to move forward or are prohibited from moving forward.
[0050] Specifically, each U-turn parking space is provided with a third sensor for sensing whether the vehicle in the U-turn parking space has completed the U-turn, and a forward indicator light for indicating forward movement according to the sensing result of the third sensor. Figure 3 A structural schematic diagram of another U-turn parking space provided in an embodiment of the present disclosure, such as Figure 3As shown, the third sensor 203 is arranged on the side where the vehicle in the U-turn parking space 200 turns, i.e., the inner side, and the forward indicator light 204 is arranged on the rear side of the U-turn parking space 200, so as to conveniently indicate the vehicle on the rear side of the U-turn parking space 200. When the vehicle in the U-turn parking space 200 starts to turn, the head of the vehicle will pass through the third sensor 203. At this time, the forward indicator light 204 starts to indicate that the rear vehicle is prohibited from moving forward because the third sensor 203 senses that the vehicle in the U-turn parking space 200 has started to turn around. When the vehicle in the U-turn parking space 200 completes the U-turn, the rear of the vehicle will leave the third sensor 203. At this time, the forward indicator light 204 starts to indicate that the rear vehicle is allowed to move forward because the third sensor 203 senses that the vehicle in the U-turn parking space 200 has completed the U-turn. Therefore, the present disclosure can avoid the situation where the vehicle behind the U-turn parking space 200 starts to move forward when the vehicle in the U-turn parking space 200 has not yet completed the U-turn, causing confusion among the vehicles in the U-turn lane and even causing traffic accidents.
[0051] In some embodiments, the third inductor includes an induction coil.
[0052] Specifically, when the front of the vehicle enters the sensing range of the induction coil, the induction coil deems that the vehicle in the U-turn parking space has started to turn; when the rear of the vehicle leaves the sensing range of the induction coil, the induction coil deems that the vehicle in the U-turn parking space has completed the U-turn. The present disclosure can sense in real time whether the vehicle in the U-turn parking space has completed the U-turn by using the induction coil, so that the U-turn monitoring of the vehicle in the U-turn parking space is more accurate, and the monitoring cost of the induction coil is lower.
[0053] In some embodiments, the monitor includes a monitoring camera, which is used to monitor whether there are vehicles parked in the n U-turn parking spaces and the m queuing parking spaces. In addition, the monitoring camera is set on a pole at the intersection where the U-turn lane is located.
[0054] Specifically, a surveillance camera is installed on the pole at the intersection where the U-turn lane is located. The surveillance camera can monitor the vehicle parking conditions in all U-turn parking spaces and queue parking spaces within the collection range. The surveillance camera monitors the number of vehicles parked in all U-turn parking spaces and queue parking spaces. When the vehicles in n U-turn parking spaces have completed their U-turns, and there are vehicles waiting in queue in the queue parking spaces exceeding the number of U-turn parking spaces. The cars in the first n queue parking spaces in the queue parking spaces drive into the U-turn parking spaces in turn, filling up all the U-turn parking spaces. At this time, when the surveillance camera detects that there are vehicles parked in all U-turn parking spaces, the indicator indicates that the vehicles in all U-turn parking spaces are allowed to turn around.
[0055] When all vehicles in n U-turn parking spaces have completed U-turns, and there are vehicles waiting in queue in the queuing parking spaces that are less than the number of U-turn parking spaces. When the monitoring camera detects that the vehicles in the queuing parking spaces move forward to the number of parking spaces where vehicles are parked, the indicator can indicate that the vehicles in the U-turn parking spaces where vehicles are parked are allowed to make U-turns. The present disclosure realizes that, through the cooperation of the monitoring camera and the indicator, the vehicles in the queuing parking spaces can only make U-turns when all the U-turn parking spaces are filled or when all the vehicles in the queuing parking spaces drive into the corresponding U-turn lanes, thereby realizing that all the U-turn parking spaces in the U-turn lanes can be used to the maximum extent, ensuring the role of the U-turn lanes in improving the traffic capacity and improving the traffic efficiency.
[0056] In some embodiments, the U-turn lane further includes a violation recording camera; the violation recording camera is used to record whether the vehicle makes a U-turn when the indicator indicates that the vehicle is prohibited from making a U-turn.
[0057] Specifically, the U-turn lane is also equipped with a violation recording camera, which can record vehicles that make a U-turn without the indicator indicating that the U-turn is allowed. When the indicator indicates that the U-turn is prohibited in the U-turn parking space, but the vehicle in the U-turn parking space makes a U-turn, the violation recording camera will take a photo of the vehicle that violates the traffic regulations and send it to the relevant agency so that the relevant vehicle can be punished.
