Abstract
The invention discloses a method for eliminating left-turn phase at traffic intersection. The method provides an improvement on the passing roads near crossroads, arrangement of left-turn green light at the road intersection can be avoided, by using the unoccupied zone due to the red light at the road intersection, the utilization rate of the road intersection sources can be increased, parking delay of the vehicles at the road intersection is reduced, traffic flow at the road intersection can be obviously increased, and the traffic jam is alleviated.
Description
Technical field
The present invention relates to a kind of method eliminating traffic intersection left turn phase, it belongs to field of road traffic.This
The road method for crossroad of inventing improves, and is effectively improved the mobility at crossing.
Background technology
Along with socioeconomic development, the road traffic in each city all occurs in that jam in various degree,
This causes Socie-economic loss to a certain extent.
Urban highway traffic mostly uses two-way multilane to travel now, and occurs that the situation of traffic congestion is usual
All occur at the parting of the ways.Current most of large-scale crossroad is designed with, keeps straight on and turn right three
Plant driving and guide road, (note: following discussion for using " keeping to the right " current road made
If indicating all for " keeping to the right " the current road made without special), generally keep straight on and right-hand rotation direction is green light
Time current, left-hand rotation guiding is still that the forbidden state of red light, adds that the crisscross upper red light in crossing is forbidden, makes a general survey of
Whole crossing wagon flow situation, is the formation of half vehicle current under green light, and second half vehicle is (even more than
Half) wait in crossing parking delay.As it is shown in figure 1, when North and South direction be green light pass through time, north and south is walked
To crossing made full use of by wagon flow, but in left-hand rotation guided vehicle road, wagon flow is still stagnated；And
East-west direction is because being that red light is forbidden, and stop and be detained in wagon flow crossing on the right side of road, and road opposite side is now
It is idle condition, such as clear area (1) in figure.
For changing an angle, it is nearly equal to be that crossing has the region of 1/4th to be in idle state,
Path resource cannot substantially effectively utilize, and this is pole for urban highway traffic pressure increases day by day
Big path resource waste.
Summary of the invention
Present invention mainly solves crossroad during vehicle pass-through, have 1/4th crossing road areas not busy
The problem put.This method under existing road traffic passing rules, proposes a kind of to exempt from the ten of left-hand rotation green light
Word crossing.The cost that this method is implemented is the lowest, but improves the utilization rate of crossing path resource to a great extent.
The present invention proposes a kind of method eliminating traffic intersection left turn phase, in the crossroad in large multi-vehicle road
Cancel left-hand rotation guided vehicle road and change Through Lane into, increase the craspedodrome of crossing road and pass through capacity and mobility, phase
The crossroad traffic signal lamp answered also changes into without left-turning traffic lamp, then sets up one at crossing four direction road
Turn around road junction (2).
As in figure 2 it is shown, turn around, road junction (2) distance crossing is in the range of 100-200m；Each at road junction of turning around
The warning region (3) of yellow cross hatch is set up in counter flow front, as it is shown on figure 3, before so can warning
Side is road junction of turning around, and improves road safety coefficient.
Turning around, road junction (2) permission is two-way turns around, and the vehicle sailing for crossing can also turn around at the road that turns around
Sail out of crossing, so want that the vehicle turned around at crossing turns around in advance, reduce non-craspedodrome in crossing waits and passing through
Vehicle fleet size；On the other hand, it is reserved with free time track (4) in direction, crossing, vehicle to be turned left,
Turn right after crossing comes, turn around to go back to crossing at the road that turns around and enter reserved idle track (4), so
Ensure that crossing four direction circulation is detoured.
As shown in Figure 4, when east-west crossing be red light crossing forbidden, south-north direction be green light pass through time,
The wagon flow travelled from south to north is according to the rules by crossing, in order to make full use of clear area, crossing, originally
To select to turn right, now because east-west crossing is after the vehicle turned left in crossing now enters crossing
Red light, east-west wagon flow is off, and on the other hand, road junction of turning around (2) are set in distance crossing 100-200m
Position, avoid to a great extent crossing wait traffic lights seniority among brothers and sisters vehicle, before road junction of additionally turning around
The warning region (3) that side is arranged reminds vehicle to be prepared to enter into road junction (2) of turning around, and wagon flow is by road junction of turning around (2)
After, enter reserved idle track (4), and then it is current to enter east-west Through Lane wait green light.
The crossroad set according to this method, when green light passes through, the transverse width at whole crossing all quilts
Utilizing, whole tracks (keep straight on and turn right) at whole crossing all flow, and this promotes to a great extent
The traffic capacity at crossing, reduces vehicle overstocking before crossing；On the other hand, clear area, crossing originally
(1) now being used by the wagon flow originally turned left and turn right, this is also greatly improved crossroad road money
The utilization rate in source.
If the road system of " keeping to the left ", then exempt from right-hand rotation green light for crossroad, then the rightest
The vehicle turned, after entering crossing, selects to turn left to enter clear area, crossing, then selects to fall at road junction of turning around
Head enters Through Lane and waits current.
The low cost that the present invention implements, and comply with current traffic passing rules；It addition, crossroad is changed
Make simple and practical, for automobile driver, it is readily understood that and accept the method that crossing is current.
Accompanying drawing explanation
Pass through schematic diagram in the crossroad that Fig. 1 is the most current.
Fig. 2 is to pass through schematic diagram in the crossroad of the present invention.
Fig. 3 is the road junction schematic diagram that turns around of the present invention.
Fig. 4 is that the current letter in crossroad of the present invention is intended to.
In figure: 1 is clear area；2 is road junction of turning around；3 is warning region；4 is idle track.
Detailed description of the invention
The current letter in the crossroad of the present invention is intended to as shown in Figure 4, is provided only with craspedodrome at the parting of the ways and turns right
Track, when east-west road be that red light is forbidden, south-north direction road be green light pass through time, south-north direction road
The vehicular movement in whole tracks of mouth is passed through, and whole crossing width is all utilized.
When vehicle is before south orientation north traveling is prepared to enter into crossing, first arrives alert zone territory (3), now imply that
Vehicle or preparation are turned around in road junction of turning around (2), or keep straight on by crossing, or turn right, and originally think
The vehicle to turn left at crossing also to be turned right at crossing；After vehicle is turned right and is entered east-west crossing, then
Secondary entrance warns region (3), imply that the vehicle to be turned right at crossing continues to keep keeping straight on, althoughs note that
Vehicle to be turned around, and turning around in the vehicle originally turned left at crossing road junction (2) of turning around in front, sails east into
The idle track (4) that crossing is reserved is moved towards in west, waits that traffic lights pass through, reaches " left-hand rotation " equally with this
Purpose.
