detailed description

The embodiment of the present application provides a road type three-way traffic signal and a traffic signal control system.

The terms "comprising" and "having", and any variations thereof, appearing in the specification, the claims, and the drawings are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or alternatively Other steps or units inherent to these processes, methods, products or equipment. Moreover, the terms "first," "second," and "third," etc. are used to distinguish different objects, and are not intended to describe a particular order. The following is an explanation of some related terms.

Referring to FIG. 1 , the relative positional relationship between the parking line and the intersection security line disposed on certain entrance lanes of the plane intersection in the embodiment of the present application may be exemplified in FIG. 1 . In the example shown in FIG. 1, a crosswalk is arranged between some entrance/exit roads and intersections of the intersections, and a crosswalk is not provided between the other entrance/exit roads and the intersections. In practical applications, some or all of the entrance/exit lanes and junctions of some of the intersections may be provided with a crosswalk, and some or all of the entrance/exit lanes and junctions of some of the intersections may not have a crosswalk. In Fig. 1, the cross-shaped intersection is taken as an example, but the intersection may also be a T-shaped plane intersection or a plane intersection of other shapes.

Among them, the entrance of the plane intersection can also be called the inlet road. An entranceway at a level intersection may include one or more entrance lanes, which may also be referred to as an entrance lane. The exit path of a plane intersection can also be called a downstream road. An exit lane at a plane intersection may include one or more exit lanes, which may also be referred to as a downstream lane. In the related drawings of the embodiments of the present application, the entrance lanes are mainly located on the right side of the corresponding exit lanes, and the entrance lanes of some countries may also be located on the left side of the corresponding exit lanes, and so on.

Wherein, if an entrance lane includes a plurality of entrance lanes, the orientations of the plurality of entrance lanes may be the same, partially identical or different from each other. The orientation of the entrance lane can be divided into left turn, straight turn, right turn and turn around. For example, an entrance lane X includes six entrance lanes. Assuming that the orientation of two of the six entrance lanes is left-turning, the two entrance lanes may be referred to as the left-turn entrance lane of the entrance lane X, left. The turn entrance lane can be referred to as the left turn lane. Assuming that the other three entrance lanes of the above six entrance lanes are oriented straight, then the three entrance lanes may be referred to as a straight entrance lane of the entrance lane X, and the straight entrance lane may be referred to as a straight lane. Assuming that the orientation of the remaining one of the six entrance lanes is a right turn, then the one entrance lane may be referred to as the right turn entrance lane of the entrance lane X, and the right turn entrance lane may be referred to as the right turn lane. analogy.

For example, a cross-shaped intersection may generally include four entrance lanes and four exit lanes, each of which may include one or more entrance lanes, each of which may include one or more exit lanes. The T-shaped plane intersection generally includes three entrance lanes and three exit lanes, each of which may include one or more entrance lanes, and each exit lane may include one or more exit lanes. Of course, the number of entrance and exit lanes at some intersections may not be equal. For example, a cross-shaped intersection may only include 3 entries. Oral and 4 exits.

In some cases, the orientation of certain entrance lanes may be variable (ie, non-fixed), for example, in some periods an entrance lane is a left turn lane, while in other periods it may be a straight lane, and this may be a straight lane. Lanes can be called guided variable lanes, and so on. In some cases, the orientation of certain entrance lanes may be multiple, for example, an entrance lane may be a straight lane and it may also be a right lane. For example, the entrance lane on the far right of an entrance road may be both a straight lane and a right lane, and this lane may be referred to as a multi-guide lane or a composite guide lane, and so on.

The driving direction of the lane is generally fixed, but in some cases, the driving direction of some lanes may also be variable (ie, non-fixed), and the lane in which the direction of travel can be changed may be referred to as a variable driving lane. The driving direction variable lane is commonly called the tidal lane. The driving direction of the tidal lane is sometimes the tidal direction, sometimes the squat direction, that is, the tidal lane can travel in the direction of the tide and the direction of the slanting direction. Switch between. It can be understood that since the traveling direction of the tidal lane is variable, for a certain tidal lane between two intersections (assumed to be the intersection LK1 and the intersection LK2), when the tidal lane is traveling in the tide direction In the direction of travel, assuming that the tidal lane is an entrance lane with respect to the intersection LK1, it is an exit lane with respect to the intersection LK2. Conversely, when the traveling direction of the tidal lane is a slanting direction, the tidal lane is opposite to the intersection LK2. The entrance lane, which is the exit lane relative to the intersection LK1, and so on. The driving direction of the lane may be, for example, eastward (ie eastbound), westward (ie westbound), southbound (ie southbound) or northbound (ie northbound). For example, if the direction of travel of an entrance road is eastward, then the left turn lane in the entrance lane is also called the eastward left turn lane. In some scenarios, the eastward left turn lane is also called the eastbound left turn lane. The straight lane in the entrance lane is also called the eastbound straight lane. In some scenes, the eastward straight lane is also called the eastbound straight lane, and so on.

In the embodiment of the present application, the intersection safety line of the lane of the intersection (such as the entrance lane and the exit lane) refers to a lane boundary line adjacent to or intersecting the intersection, or a lane boundary line adjacent to or intersecting with the pedestrian crossing. Wherein, the parking line of the entrance lane can be set at the intersection safety line position of the entrance lane. Alternatively, the parking lane of the entrance lane may be disposed after the intersection safety line of the entrance lane with respect to the direction of travel of the entrance lane. In the conventional technology, the parking lane of the entrance lane is generally disposed at the intersection safety line position of the entrance lane, and the parking lane and the intersection security line are combined in a spatial position. In some embodiments of the present application, mainly in the direction of travel relative to the entrance lane, the parking lane of the entrance lane is disposed after the intersection security line of the entrance lane as an example, that is, the solution of some embodiments of the present application Breaking through the inertial thinking of setting the parking line at the intersection safety line position of the entrance lane, boldly and innovatively separating the parking lane of the entrance lane and the intersection safety line in a spatial position, and the parking lane of the entrance lane is safe relative to the intersection of the entrance lane. The line moves backwards, creating a new way of parking line layout. The setting position of the parking lane of the entrance lane may be relatively fixed, that is, the distance between the intersection safety line of the entrance lane and the parking lane of the entrance lane may be relatively fixed, and of course, the entrance lane may be based on factors such as environmental factors and scene requirements. The position of the parking line is adjusted to suit the position. The lane segment defined between the intersection safety line and the parking lane of the entrance lane may be referred to as a guiding zone of the entrance lane, and the guiding lane of the entrance lane may also be regarded as a pre-acceleration zone, and the parking lane of the entrance lane may be regarded as The entrance end line of the corresponding guiding area, the intersection safety line of the entrance lane can be regarded as the exit end line of the corresponding guiding area. In particular, for the tidal lane, there may be a tidal intersection safety line, a tidal direction parking line and a tidal direction guiding area corresponding to the tidal direction of travel, and there may also be a slanting intersection safety line corresponding to the direction of the squatting direction,汐 to the parking line and to the guiding area. Wherein, the outlet end line of the tide direction guiding area is a tide direction intersection safety line, and the inlet end line is a tide direction parking line. Wherein, the exit end line of the slanting guide area is a slanting intersection safety line, and the entrance end line is a slanting stop line.

In other words, when the parking lane of an entrance lane and the intersection security line are separated in a spatial position, the lane segment delineated between the parking lane of the entrance lane and the intersection security line can form a guiding area of the entrance lane. . When the stop line and the intersection safety line of an entrance lane are combined in a spatial position, the guiding area of the entrance lane does not exist. As exemplified in FIG. 1, the parking line and the intersection safety line of some entrance lanes of the plane intersection are separated in spatial position (ie, the entrance lane has a guiding area), and FIG. 1 also The parking line and the intersection security line of some entrance lanes illustrating a plane intersection are combined in a spatial position (ie, there is no guiding area in the entrance lane). In practical applications, some of the entrance lanes of some of the intersections have a guiding area, and the remaining part of the entrance lanes do not have a guiding area. There may also be no guiding areas in all entrance lanes of some of the intersections, and there may be guiding areas in all the entrance lanes of some of the intersections. Whether the parking lane of the entrance lane and the intersection security line are separated in the spatial position can be determined according to the actual scene.

Vehicles in each lane of a plane intersection may be allowed to pass under the control of traffic lights (allowing traffic to be referred to as permission) or prohibiting traffic (no access may be referred to as prohibition) or warning traffic (alert traffic may be referred to as police traffic) In general, a traffic light corresponding to an entrance lane can control the permission or alarm or prohibition of the vehicle on the entrance lane. Wherein, controlling the phase of the vehicle on the entrance lane may be referred to as the passage phase of the entrance lane (the traffic phase may also be referred to as a release phase or a permitted phase), and the color of the optical signal emitted by the corresponding traffic signal in the conventional art. In the conventional phase, the traffic phase is generally referred to as the green light phase. In the technical solution of the embodiment of the present application, the color of the optical signal emitted by the corresponding traffic light during the transit phase is not limited to green. And can be extended to be any single color or combination of colors that can be used to indicate that the vehicle is allowed to pass. The color of the light signal emitted by the corresponding traffic signal during the transit phase is green, which is an optional implementation in the embodiment of the present application. The only way. The phase of controlling the forbidden line of the vehicle on the entrance lane can be referred to as the forbidden phase of the entrance lane. In the conventional technology, since the color of the light signal emitted by the corresponding traffic signal is red during the forbidden phase, the conventional technology The forbidden phase is also generally referred to as a red light phase. In the embodiment of the present application, the color of the light signal emitted by the corresponding traffic light during the forbidden phase is not limited to red, but may be extended to be used to indicate that the vehicle is prohibited from passing. Any one color or combination of several colors, the color of the light signal emitted by the corresponding traffic signal during the forbidden phase is red. This is an optional implementation in the embodiment of the present application. Similarly, controlling the phase of the vehicle's police line on the entrance lane may be referred to as the police line phase of the entrance lane (the police phase may also be referred to as the transition phase). In the conventional art, the color of the light signal emitted by the corresponding traffic signal is in the police. The phase of the line is yellow. Therefore, the phase of the alarm in the conventional technology is also generally referred to as the phase of the yellow light. In the embodiment of the present application, the color of the light signal emitted by the corresponding traffic signal during the phase of the police is not limited to yellow, but may be Expanded to any single color or color combination that can be used to indicate the passage of the warning vehicle. The color of the light signal emitted by the corresponding traffic signal during the alert phase is yellow. This is an optional implementation in the embodiment of the present application.

In particular, the “phase” mentioned in some traffic codes generally defaults to the transit phase (such as the green light phase), that is, in some traffic codes, the traffic phase (such as the green light phase) is simply referred to as the phase. Not even paying special attention to the concepts of forbidden phase and transition phase. The solution of the embodiment of the present application mainly aims to implement relatively fine control management for each lane, and thus particularly distinguishes different phase concepts such as the transit phase, the forbidden phase and the transition phase.

In general, the continuous transit phase, transition phase, and forbidden phase of an entrance lane may form a single phase period of the entrance lane, and the total duration of two adjacent phase periods may be fixed (as shown in the example of FIG. 2) The total duration of two adjacent phase periods of the entrance lane 01 is 60 seconds) or is not fixed (the total duration of the adjacent two phase periods of the entrance lane 02 shown in the example of FIG. 2 is not equal). The phase-period settings of the two entrance lanes of the same orientation of the same entrance lane may be the same (the phase periods of the two left-turn lanes of the entrance lane Y are the same as shown in the example of FIG. 5) or different. The phase period settings of the two entrance lanes of different orientations of the same entrance lane may be the same or different. In some scenarios, the transition phase may even be absent. In this case, the phase period includes only the transit phase and the forbidden phase, and does not include the transition phase.

The concept of “road crossing conflict lane” is proposed below. The intersection conflict lane is a relative concept. When two entrance lanes are intersection collision lanes, it means that there is a crossover (or existence) of the traffic trails on the two entrance lanes passing through the intersection. Interlacing), that is, there is a crossover of the traffic trajectory of any two entrance lanes that are mutually conflicting lanes passing through the intersection. For example, the east-west straight lane and the north-south straight lane are crossroad conflict lanes, and there is a crossover between the east-west straight lane and the north-south straight lane. As shown in Fig. 3, if the traffic on the westbound straight lane and the southbound straight lane pass through the intersection at the same time, the two traffic flows will collide at the intersection. Figure 3 also shows, by way of example, that the westbound straight lane and the northbound straight lane are also mutually conflicting lanes, and the other are mutually conflicting lanes. In the embodiment of the present application, the intersection conflict lane may be referred to as a conflict lane.

The concept of "junction conflict passage phase" is proposed below, and the intersection phase of intersection intersection is also a relative concept. To put it simply, the transit phases of the two entrance lanes that are mutually conflicting lanes are mutually intersecting passage phases. Similarly, the transition phases of the two entrance lanes that are mutually conflicting lanes are the intersection transition phases of the intersections. In the embodiment of the present application, the intersection collision passage phase may be referred to as a collision passage phase. The transition phase of the intersection conflict can be referred to as the collision transition phase.

The concept of "control phase" and "non-control phase" is proposed below. The control phase of the entrance lane is used to control the traffic on the entrance lane to cross the intersection, which means that the traffic on the entrance lane has passed the intersection. right. Among them, those vehicles that drive through the stop line of an entrance lane at the end of the transition phase (if any) or at the end of the traffic phase usually take a certain amount of time to cross the intersection, in order to avoid collision between these vehicles and the lane from another intersection. Vehicles at the intersection are at conflict at the intersection. Therefore, some traffic codes suggest that these vehicles usually take about 2 seconds to ensure that the vehicles that pass through the transition phase (if any) or the end of the traffic phase can safely drive. At the intersection, in some traffic codes, the time for emptying is referred to as the empty phase (where the emptying phase is similar to the all-red hour of the intersection referred to in some traffic codes). In general, on the time axis, the control phase of an entry lane + the non-control phase = the transit phase of the entry lane + the forbidden phase + the transition phase (if any). The forbidden phase can include clearing the phase and non-clearing the phase. Of course, emptying the phase may not be necessary under certain special circumstances. When the empty phase does not exist, the forbidden phase may be equivalent to the non-control phase, that is, the non-control phase of the entrance lane is the entrance lane. Part or all of the forbidden phase. Where there is a transition phase and a clear phase, the control phase may include a transit phase, a transition phase, and an empty phase. In the case where there is a transition phase without emptying the phase, the control phase includes a transit phase and a transition phase. In the case where there is no transition phase but there is a clear phase, the control phase includes the transit phase and the clear phase. In the absence of a transition phase and a clear phase, the control phase can be equivalent to the transit phase. For example, FIG. 4 exemplifies that the control phase of an entry lane (eg, entrance lane x05) includes a transit phase, a transition phase, and an empty phase; or a control phase of an entry lane (eg, entrance lane x07) may include a transit phase And emptying the phase; or the control phase of an entry lane (eg, entrance lane x06) includes the transit phase and the transition phase; or the control phase of an entry lane (eg, entrance lane x08) may be equivalent to the transit phase. The phase mentioned in some traffic codes may also default to the control phase, that is, in these traffic specifications, the control phase may be simply referred to as phase.

The concept of "intersection conflict control phase" is proposed below. The intersection control phase is a relative concept. In simple terms, the control rights of the two entrance lanes of each other are the intersection control phase. The intersection conflict control phase can be referred to as the conflict control phase.

The above description of various concepts (such as the "phase" concept) is mainly based on the case of lanes. Certain concepts for lanes (such as certain "phase" concepts) can also be applied to scenes for crosswalks. In a broad sense, crosswalks and lanes can be regarded as roadways. Passages are roads used for traffic passages. Crosswalks include crosswalks and lanes (such as entrance lanes, exit lanes, etc. at plane intersections). Among them, the object passing through the traffic lane is called a traffic object (the traffic object may be a pedestrian or a vehicle, etc.), and the object flow passing through the traffic lane is called a traffic flow (referred to as a traffic flow). The objects passing through the crosswalk may include pedestrians, etc., and the flow of objects passing on the crosswalk includes pedestrian flow and the like. For example, an object passing through a lane may include a vehicle or the like, and a flow of objects passing through the lane includes a traffic flow or the like.

For the scene of the crosswalk, there may also be concepts such as the traffic phase, transition phase and forbidden phase of the crosswalk. There may also be concepts such as the control phase and the non-control phase of the crosswalk. There may also be conflicts between the crosswalk and certain lanes, as the flow of people on the crosswalk and the trajectory of traffic on a lane may intersect. Broadly speaking, when two passways (the two passways may If there is a lane, or maybe one of them is a lane, and the other is a crosswalk, there is a crossing of the trajectory of the traffic, then the two passages can be called conflicts, and the two passages of each other are conflicting lanes. The traffic on the road passes through the same time period, and the traffic on the two traffic lanes may collide. If the conflict road of a traffic lane (such as a lane or a crosswalk) is a lane, the conflict lane may also be referred to as a conflict lane; if the conflict lane of a traffic lane is a crosswalk, the conflict lane may also be referred to as a conflicting crosswalk. There may be conflicts between lanes and lanes, and lanes and crosswalks may also conflict with each other. Among them, conflict lanes and conflict crosswalks can be collectively referred to as conflict lanes.

In order to simplify the description, in the description of the solution of the present application, the forbidden traffic light signal may be referred to as a forbidden light signal or an A1 class light signal, and the pass light signal may be referred to as an allowable light signal or a traffic light signal or an A2 light signal for warning. The optical signal may be referred to as an alarm light signal or an A3 type optical signal. Specifically, the forbidden light signal is an optical signal for indicating the passage of a traffic object (such as a vehicle or a pedestrian, etc.) that prohibits a corresponding traffic lane (such as a lane or a crosswalk, etc.), for example, a traffic light of a lane is banned. During the light signal, the traffic of the lane is prohibited, and the traffic signal of a pedestrian crossing prohibits the traffic of the pedestrian crossing during the prohibition of the light signal. The allowable optical signal is an optical signal for indicating the passage of a traffic object (such as a vehicle or a pedestrian, etc.) that allows a corresponding traffic path (such as a lane or a crosswalk, etc.), for example, when a traffic signal of a lane emits a permitting optical signal. The vehicle in the lane passes, and the traffic signal of a pedestrian crossing sends out the traffic of the pedestrian crossing during the period when the light signal is allowed. The police light signal is an optical signal used to indicate the passage of a traffic object (such as a vehicle or a pedestrian) that alerts a corresponding traffic lane (such as a lane or a pedestrian crossing), such as a vehicle that alerts the lane during a traffic light signal of a lane. Passing, the traffic light of a pedestrian crossing signal alerts the pedestrian crossing during the warning light signal. Other situations can be deduced by analogy.

The specific presentation forms of the forbidden optical signal, the allowed optical signal, and the police optical signal may be flexible and can be set according to specific scene requirements. For example, the forbidden light signal may be a red light signal, wherein the red light signal may specifically be a blinking red light signal and/or a non-flashing red light signal. The non-flashing red light signal may be simply referred to as a constant red light signal, and the flashing red light signal may be simply referred to as a red flash signal. The forbidden light signal is an optical signal for indicating the passage of a prohibited traffic object (such as a vehicle or a pedestrian), and therefore any optical signal that can be used to indicate the passage of a traffic object (such as a vehicle or a pedestrian) that prohibits the corresponding traffic lane is It can be regarded as a forbidden optical signal, and the representation of the forbidden optical signal is not limited to the above examples. For example, optical signals of several colors may be combined according to certain rules to indicate that the passage of the corresponding passage is prohibited. Then these forms of optical signals can also be considered as forbidden optical signals.

For another example, the allowed optical signal may be a green optical signal, and the green optical signal may specifically be a blinking green optical signal and/or a non-flicking green optical signal. The non-flickering green light signal may be referred to as an evergreen light signal, and the flashing green light signal may be simply referred to as a green flash signal. The permission optical signal is an optical signal for indicating the passage of a traffic object (such as a vehicle or a pedestrian) that allows the corresponding traffic lane, and therefore, any one of the traffic objects (such as a vehicle or a pedestrian) that can be used to indicate the permission of the corresponding traffic lane. The passing optical signal can be regarded as the optical signal, and the representation of the optical signal is not limited to the above examples. For example, optical signals of several colors can be combined according to certain rules to indicate that the passing object is allowed to pass. Then, these forms of optical signals can also be considered as allowing optical signals.

For another example, the police light signal may be a yellow light signal, and the yellow light signal may specifically be a blinking yellow light signal and/or a non-flashing yellow light signal. The non-flickering yellow light signal may be referred to as a normally yellow light signal, and the flashing yellow light signal may be simply referred to as a yellow flash signal. The police light signal is an optical signal used to indicate the passage of a traffic object (such as a vehicle or a pedestrian) that alerts the corresponding traffic lane. Therefore, any type of traffic object (such as a vehicle or pedestrian) that can be used to indicate the corresponding traffic lane is indicated. The pass light signal can be regarded as a police light signal, and the manifestation of the police light signal is not limited to the above examples. For example, light signals of several colors can be combined according to certain rules for indicating the warning pass. Objects pass, then these forms of optical signals can also be considered as police light signals.

In general, the allowed optical signal may exist in one or more manifestations, and the forbidden optical signal may also exist in one or more representations, and the alert optical signal may also exist in one or more representations. However, due to the permission of the optical signal, the forbidden optical signal and the warning light signal Differently, the expressions of the allowed optical signal, the forbidden optical signal and the police optical signal are also different from each other, that is to say, the expression set of the forbidden optical signal, the manifestation of the manifestation of the police optical signal and the prohibition There is no intersection between the representations of the line of light signals.

Wherein, the police light signal is used to indicate the light signal of the traffic object (such as a vehicle or a pedestrian) that alerts the corresponding traffic lane, so that the police light signal can be regarded as a transition signal from a certain angle ( Therefore, the police light signal can also be referred to as an excessive light signal), indicating that the transit object transitions between the allowed and the forbidden lines. In some cases, if such a transition is not required, then there may be no need to monitor the transition signal of the optical signal.

A signal lamp capable of emitting an A2 type optical signal but not capable of emitting an A1 type optical signal and an A3 type optical signal may be referred to as an "A2 type signal lamp".
