Description
Technical Field
The invention relates to the field of road traffic control methods, in particular to a one-way multi-way cooperative traffic method for urban roads.
Background
The ministry of public security and traffic, 25 days 3 and 3 of 1972, jointly promulgated the 'urban and highway traffic management rules', and then gradually formed the existing traffic rules through continuous revision and enrichment and the promulgation of other relevant traffic management rules. In the existing traffic rules, the traffic mode of a common urban road intersection is a two-way one-way traffic method, namely, the traffic at the intersection is divided into two-way straight green light traffic or two-way left-turn green light traffic, and the right-turn vehicles and pedestrians are generally not limited, and the traffic light time between all intersections in the whole city is not coordinated or is difficult to be coordinated, so that the vehicles and the like are often blocked on the road to wait for red light instead of driving on the road, the urban traffic efficiency is low, and motor vehicles and non-motor vehicles have crossed routes at the intersection, so that the traffic jam is abnormal and accidents are frequent.
Disclosure of Invention
In order to overcome the defects of the existing traffic method or traffic rules, the invention provides a one-way multi-way cooperative traffic method.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a single-pass multi-direction cooperative traffic method comprises the following steps:
The urban road has south-north east-west direction, the east-west direction is represented by coordinate value "n", the south-north direction is marked by coordinate value "m", and each direction crossing in the (n, m) th crossroads is respectively marked by A(n,m)、B(n,m)、C(n,m)、D(n,m)Marking; the east-west trend is called street, the south-north trend is called road, the distance between the n-1 th road and the n-th road of the mth street is Lm (n-1,n)Marking, L for distance between the (m-1) th street and the (m) th street crossroad on the nth roadn (m-1,m)Marking;
step 2, define
The 'single pass' is A(n,m)、B(n,m)、C(n,m)、D(n,m)Four intersections pass through only one intersection at a time, the four intersections pass through in sequence, and the passing period and the total passing time are defined as T(n,m)＝TA(n,m)+TB(n,m)+TC(n,m)+TD(n,m)Wherein T isA(n,m)……TD(n,m)Respectively setting the passing time of each intersection; t ism L(n,n+1)For vehicles passing through mth street A(n,m)And A(n+1,m)Coordinated time, v, required for road junction routesm (n,n+1)For vehicles passing through mth street A(n,m)And A(n+1,m)The speed of the intersection trip needs to be coordinated;
the multi-direction is that when each intersection executes single-pass, all the lanes of each intersection pass in a plurality of directions of left-turning, straight-going, right-turning and turning around;
step 3, collaboration
When it is in the first place(n,m)When the intersection is at the green light passing time at the time t, the cooperative driving speed v is obtainedm (n,n+1)And A(n,m)And A(n+1,m)Distance L between road junctionsm (n,n+1)Calculating to obtain Tm L(n,n+1)＝Lm (n,n+1)/vm (n,n+1),A(n+1,m)Green light at the intersection tn+1＝t+Tm L(n,n+1)Is constantly on, A(n+1,m)Intersection green light passing time and driving time Tm L(n,n+1)In terms of period and multiple (which is generally 1/2 regardless of yellow light time), and A is obtained based on the algorithm(n+1,m)The crossing traffic time and the traffic time are analogized, so that when a straight-going vehicle in the west-east direction of the mth street passes through an urban road, the vehicle encounters a red light or a cooperative driving speed, and then the vehicles encounter green lights;
due to A(n,m)And A(n+1,m)Distance to intersection C(n,m)And C(n+1,m)The distances of the intersections are the same and are all Lm (n,n+1)Therefore, in general, A(n,m)And C(n+1,m)The green light should be turned on at the same time at the intersection, namely C(n+1,m)And A(n,m)The intersection passes simultaneously, and according to the above, when the straight-going vehicle in the mth street from east to west passes through the urban road, the vehicle encounters a red light or the cooperative driving speed, and then the vehicle encounters a green light;
step 4, after the east-west passing time and the passing time of each crossroad of the mth street are determined, coordinating the running speed v according to the north-south direction of the nth roadn (m,m+1)Sequentially calculating the distance between the mth street and the (m + 1) th street crossroad to obtain the passing time and the passing time of each intersection of the (m + 1) th street, and so on;
therefore, the cooperative traffic of all streets and roads can be realized, and all straight vehicles passing through the urban roads are under the green light when meeting a red light or the cooperative driving speed.
In the present invention, the "cooperative running speed v" is defined asm (n,n+1)"is a variable, rather than constant, value, as is vm (n,n+1)Relative crossing transit time T(n,m)Is also a variable value, and T is a time required for the vehicle to pass through the intersection(n,m)It is necessary to be larger than a certain value, but due to the above-mentioned relationship, T is generally increased(n,m)Will make vm (n,n+1)Decrease, vm (n,n+1)Decreasing means that the traffic speed is slow, so T(n,m)And vm (n,n+1)A balance value is taken in a certain reasonable interval according to the road condition and the traffic flow. The value of which is related to the distance L between each intersection and the traffic flow, generally Lm (n,n+1)V is smaller and the traffic flow is largerm (n,n+1)The smaller, i.e. vm (n,n+1)With Lm (n,n+1)And changes accordingly.
Furthermore, after the passing time and the passing time of each crossroad are calculated according to the distance between the crossroad and the speed of the coordinated vehicle, the network control is carried out through programming, and the traffic command center adjusts the passing time and the passing time of each crossroad at any time according to the traffic flow condition so as to improve the passing efficiency.
Further, each intersection is provided with a non-motor vehicle left-turning waiting area in front of each non-motor vehicle lane so as to avoid the left-turning non-motor vehicles from forming a route intersection with the motor vehicles.
Furthermore, each traffic lane in each intersection is set to be capable of going straight or turning left or capable of going straight or turning right, so that the red light waiting vehicle queuing length at the intersection is shortened.
Further, when the distance L of each crossroad in the cityn (m-1,m)And Lm (n-1,n)And when the n and the m are different and unequal, the cooperative traffic of all streets and roads cannot be realized, the passing time and the passing time of each crossroad are set to mainly ensure that the vehicles can be driven smoothly in a certain direction.
The invention has the following beneficial effects:
the definition of 'one-way and multi-way' is a basis, on the basis, the passing time and the passing time of each crossroad are set through an algorithm, and the urban traffic can have reasonable period and rhythm through the coordinated driving speed, so that the passing of each crossroad can be coordinated, and the situation that the vehicles meet a red light and the following green lights when going out is achieved as much as possible.
In the invention, if the traffic lights at each crossroad are networked and programmed, the traffic command center can adjust the passing time and the passing time of each crossroad at any time according to the traffic flow condition so as to improve the passing efficiency.
Compared with the prior art, the urban traffic control system can coordinate the whole urban traffic, and conveniently adjust the running time of each direction of each intersection according to the traffic condition, thereby greatly improving the urban traffic efficiency, relieving the congestion condition of the current urban traffic, well controlling the urban speed, effectively avoiding the occurrence of overspeed and traffic accidents, and being inestimable in economic and social benefits.

Detailed Description
Example 1
Referring to fig. 1, a single-pass multi-directional cooperative transportation method includes the following steps:
The urban road has south-north east-west direction, the east-west direction is represented by coordinate value "n", the south-north direction is marked by coordinate value "m", and each direction crossing in the (n, m) th crossroads is respectively marked by A(n,m)、B(n,m)、C(n,m)、D(n,m)Marking; the east-west trend is called street, the south-north trend is called road, the distance between the n-1 th road and the n-th road of the mth street is Lm (n-1,n)Marking, L for distance between the (m-1) th street and the (m) th street crossroad on the nth roadn (m-1,m)Marking;
step 2, define
The 'single pass' is A(n,m)、B(n,m)、C(n,m)、D(n,m)Four intersections pass through only one intersection at a time, the four intersections pass through in sequence, and the passing period and the total passing time are defined as T(n,m)＝TA(n,m)+TB(n,m)+TC(n,m)+TD(n,m)Wherein T isA(n,m)……TD(n,m)Respectively setting the passing time of each intersection; t ism L(n,n+1)For vehicles passing through mth street A(n,m)And A(n+1,m)Coordinated time, v, required for road junction routesm (n,n+1)For vehicles passing through mth street A(n,m)And A(n+1,m)The speed of the intersection trip needs to be coordinated;
the multi-direction is that when each intersection executes single-pass, all the lanes of each intersection pass in a plurality of directions of left-turning, straight-going, right-turning and turning around;
step 3, collaboration
When it is in the first place(n,m)When the intersection is at the green light passing time at the time t, the cooperative driving speed v is obtainedm (n,n+1)And A(n,m)And A(n+1,m)Distance L between road junctionsm (n,n+1)Calculating to obtain Tm L(n,n+1)＝Lm (n,n+1)/vm (n,n+1),A(n+1,m)Green light at the intersection tn+1＝t+Tm L(n,n+1)Is constantly on, A(n+1,m)Intersection green light passing time and driving time Tm L(n,n+1)In terms of period and multiple (which is generally 1/2 regardless of yellow light time), and A is obtained based on the algorithm(n+1,m)The crossing passing time and the passing time are analogized, so that the straight-going vehicle in the west-east direction of the mth street is in the urban roadWhen the road passes, after meeting a red light or cooperating with the driving speed, the following green lights;
due to A(n,m)And A(n+1,m)Distance to intersection C(n,m)And C(n+1,m)The distances of the intersections are the same and are all Lm (n,n+1)Therefore, in general, A(n,m)And C(n+1,m)The green light should be turned on at the same time at the intersection, namely C(n+1,m)And A(n,m)The intersection passes simultaneously, and according to the above, when the straight-going vehicle in the mth street from east to west passes through the urban road, the vehicle encounters a red light or the cooperative driving speed, and then the vehicle encounters a green light;
step 4, after the east-west passing time and the passing time of each crossroad of the mth street are determined, coordinating the running speed v according to the north-south direction of the nth roadn (m,m+1)Sequentially calculating the distance between the mth street and the (m + 1) th street crossroad to obtain the passing time and the passing time of each intersection of the (m + 1) th street, and so on;
therefore, the cooperative traffic of all streets and roads can be realized, and all straight vehicles passing through the urban roads are under the green light when meeting a red light or the cooperative driving speed. In the present embodiment, the "coordinated traveling speed v" is describedm (n,n+1)"is a variable, rather than constant, value, as is vm (n,n+1)Relative crossing transit time T(n,m)Is also a variable value, and T is a time required for the vehicle to pass through the intersection(n,m)It is necessary to be larger than a certain value, but due to the above-mentioned relationship, T is generally increased(n,m)Will make vm (n,n+1)Decrease, vm (n,n+1)Decreasing means that the traffic speed is slow, so T(n,m)And vm (n,n+1)A balance value is taken in a certain reasonable interval according to the road condition and the traffic flow. The value of which is related to the distance L between each intersection and the traffic flow, generally Lm (n,n+1)V is smaller and the traffic flow is largerm (n,n+1)The smaller, i.e. vm (n,n+1)With Lm (n,n+1)And changes accordingly.
The embodiment is applied to urban traffic vehicles under ideal conditions, namely, urban planning is more regular, and the distance L between each intersection in the city is largern (m-1,m)And Lm (n-1,n)Approximately equal ideal.
For example, a city street and street, and a road are all separated by 700m, and each intersection is located at a side length Lm (n,n+1)On a square grid of 700m, then under normal traffic conditions, a coordinated transit time of 100s, i.e. T, may be set(n,m)100s, and TA(n,m)＝TB(n,m)＝TC(n,m)＝TD(n,m)25s, then Tm L(n,n+1)50s (not considering yellow time), coordinated driving speed vm (n,n+1)＝Lm (n,n+1)/Tm L(n,n+1)700/50-14 m/s, about 50.4 km/h. If the traffic flow is small, T can be shortened(n,m)Value so that v can be increasedm (n,n+1)The value is obtained.
The method can enable the whole urban traffic to be coordinated, particularly for straight-going vehicles, all the vehicles which meet the red light (or the coordinated driving speed) can be green light, so that the vehicles can be enabled to walk on the road instead of being enabled to walk on the road, the urban road traffic utilization rate is greatly improved, and traffic jam is relieved.
Example 2
The single-pass multi-way cooperative traffic method is based on the embodiment 1.
When the distance L of each crossroad in the city is in realityn (m-1,m)And Lm (n-1,n)When n and m are different but unequal, and when the difference is large, the situation that the passing time T of all intersections and the collaborative driving speed v of all road sections can not be guaranteed to obtain reasonable or ideal values occurs, namely when the collaborative traffic of all streets and roads can not be realized, the passing time and the passing time of each intersection are set to mainly guarantee that the driving of a certain direction/a main road is smooth.
If some cities show that east and west narrow distribution, or streets in east and west directions are main streets of the cities and each street is not straight, the passing time of each crossroad can be set mainly by ensuring that the vehicles in east and west directions run smoothly according to the method of the invention, the passing time of the crossroad A and the passing time of the crossroad C are set preferentially, the passing time can be prolonged properly, the passing time of the crossroad B and the passing time of the crossroad D are shortened, and the passing time of each street can be set independently relative to the passing time and time of the crossroad A and the passing time of the crossroad C, and the coordination condition of each road is not considered or is less considered, so that the smooth passing of vehicles in east and west directions can be ensured.
Example 3
The single-pass multi-way cooperative traffic method is based on the embodiment 1.
And after the passing time and the passing time of each crossroad are calculated according to the distance of the crossroad and the speed of the cooperative vehicle, the networking control is carried out through programming.
The urban traffic command center can conveniently adjust the green light passing time of each direction of each intersection according to the traffic condition, and the green light passing time of each direction of each intersection can be linked through simple programming control. For example, the north of a city is a residential area, the south is an industrial area, and there are many vehicles from north to south every morning when the city is on work, and many vehicles from south to north every morning when the city is off work. According to the method, the passing time of each intersection from north to south can be prolonged and the passing time of each intersection from south to north can be shortened every morning, namely, the passing time of all intersections D is prolonged and the passing time of all intersections B is shortened without influencing the traffic vehicles in the east-west direction (the passing time of the intersections A and the intersections C). And vice versa.
Example 4
The single-pass multi-way cooperative traffic method is based on the embodiment 1.
Referring to fig. 2, each intersection is provided with a non-motor left-turn waiting area before each non-motor lane.
The embodiment divides the left turn of the non-motor vehicle into two straight steps for implementation, and the non-motor vehicle needs to turn left at A(n,m)Enter into B when crossing passes(n,m)"non-motor vehicle left turn waiting area" in front of the intersection, at B(n,m)When the crossing passes through, the vehicle can go straight through the crossing,the method can avoid the intersection of the non-motorized traffic and the motorized traffic and reduce the occurrence of accidents.
According to the traffic flow condition, each traffic lane in each intersection can be set to be capable of going straight or turning left or capable of going straight or turning right, so that the red light waiting vehicle queuing length at the intersection is shortened.
While various embodiments of the present invention have been described above, it will be apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, which are merely preferred embodiments of the present invention and are not to be considered as limiting the scope of the invention.
