Description
Technical field
Intersection traffic system is the important step of urban traffic.The utility model is a kind of novel intersection traffic system, and namely the back-shaped traffic system in intersection, can realize urban automobile barrier free accessibility, cancel traffic lights, back-shaped traffic system is easy, is easy to promote, and greatly can improve convenience and the efficiency of urban traffic.
Background technology
The traffic of city intersection is most important, and each road all has three traffic directions in intersection: forward, turn left and turn right, and wherein turns right not disturb with the road in other directions, can barrier free accessibility; Forward and turn left and mutually to disturb with the road traffic in other directions, thus will arrange traffic lights and carry out control, motor vehicle or pedestrian are all closed to traffic at red light, amber period in intersection, and the traffic lights of intersection is restriction urban traffic principal element smoothly.The relatively good solution of footpound force traffic, method is also more, but motor vehicle the traffic problems of intersection compare be difficult to solve.At present, there are many methods to improve the traffic of intersection, as arranged viaduct, tunnel and round turntable etc., all can not solve the traffic problems of intersection very well.Therefore, the traffic problems of intersection are the problems of urban highway traffic most critical.
Utility model content
The utility model provides a kind of novel crossed crossing traffic system, i.e. the back-shaped traffic system in intersection, mainly solves the problem of city intersection traffic restriction.
The back-shaped traffic system in intersection, it is characterized in that: back-shaped passage is set on the road in any one direction, intersection, back-shaped passage is two bending channel compositions becoming 180 ° to turn to, bending channel is separately positioned on the both sides of intersection, position is near intersection and keep certain distance, bending channel can be tunnel, also can be viaduct.
For ease of explanation, the two road that intersection is intersected are called straight way and lateral road, four current directions are called before straight way, after straight way, the lateral road left side and the lateral road right side, and suppose that back-shaped channel setting is on lateral road, therefore, there are left bending channel and right bending channel, specifically have left curved tunnels and right curved tunnels or have left bending viaduct and the right side to bend viaduct.
(1) the back-shaped traffic system operating principle in intersection:
A back-shaped traffic system in intersection is made up of two parts: two become 180 ° of bending channels turned to form, specifically left curved tunnels and right curved tunnels or have left bending viaduct and the right side to bend viaduct, bending channel is separately positioned on the both sides of intersection, and position is near intersection and keep certain distance.
Because People's Bank of China's problem of passing through can utilize tunnel, street or overline bridge to solve, only autos only problem was discussed here.
Assuming that back-shaped channel setting is on lateral road, then lateral road keep straight on and all directions turn right all unblocked, other situations are described below.
Lateral road travels from left to right: keep straight on and turn right and be all unblocked.Turn left in intersection the front of straight way, need to keep straight on through intersection, then enter right bending channel, out, on the right side of intersection, on lateral road, direction, for travel from right to left, is got back to intersection and is turned right, and can enter straight way front.
Lateral road travels from right to left: keep straight on and turn right and be all unblocked.Turn right in intersection the rear of straight way, need to keep straight on through intersection, then enter left bending channel, out, on the left of intersection, on lateral road, direction, for travel from left to right, is got back to intersection and is turned right, and can enter straight way rear.
Straight way travels from back to front: turn right all unblocked.To turn left in intersection the left of lateral road and the front of straight way, need to turn right in intersection, then right bending channel is entered, out on the right side of intersection on lateral road direction for travel from right to left, get back to intersection to turn right, straight way front can be entered or get back to intersection and keep straight on, the left of lateral road can be entered.
Straight way travels from front to back: turn right all unblocked.To turn left in intersection the right of lateral road and the rear of straight way, need to turn right in intersection, then left bending channel is entered, out on the left of intersection on lateral road direction for travel from left to right, get back to intersection to turn right, straight way rear can be entered or get back to intersection and keep straight on, the right of lateral road can be entered.
By analyzing above, known each bar road, all directions are all unblocked.
The feature of the back-shaped traffic system in intersection is: 1. the back-shaped traffic system in intersection becomes 180 ° of bending channels turned to form by two, namely on the road in any one direction, intersection, arrange pair of curved passage and form back-shaped passage, the position of bending channel is not limited to intersection scope, as long as close intersection also keeps certain distance so that motor vehicle adjustment track, thus structure is simple, arrange easy, be easy to apply.2. main traffic road junction in city all adopts back-shaped traffic system, can guarantee that vehicle smooth is without hindrance, vehicle arbitrarily can turn direction in each intersection, overcomes current road closed and causes motor vehicle once miss certain crossing, just be difficult to later, namely road fault-tolerant ability is strong; 3. main traffic road junction in city all adopts back-shaped traffic system, once there is accident blocked road in certain section of road, after vehicle, intersection can be selected everywhere to use this road, avoid accident section, namely emergent and regulating power is strong; 4. main traffic road junction in city all adopts back-shaped traffic system, and when motor vehicles travel, mutually interference is minimum, rules of the road and walking rule similar, be not easy to occur rule errors, greatly reduce traffic accident, namely safety is high; 5. main traffic road junction in city all adopts back-shaped traffic system, and without waiting time, reduce and be open to traffic the time, greatly improve traffic efficiency, improve road Traffic Volume, namely the traffic volume is large, efficiency is high.
(2) the back-shaped traffic system method for designing in intersection
The back-shaped traffic system in intersection can be arranged on arbitrary road of intersection, but is preferably disposed on turnpike road.The position of two bending channels is mainly determined in the design of the back-shaped traffic system in intersection, the position of bending channel should keep far from intersection, see Fig. 1 and Fig. 2, before motor vehicle enters bending channel and after using bending channel, enough distances are all had to carry out lane change adjustment, avoid motor vehicle shunt and and flow time cause obstacle, concrete distance will be determined according to topographic features and vehicle flowrate.
Bending channel should according to landform and road surface once situation determine to adopt bending tunnel or bending viaduct, can be that bending channel is tunnel, can be also all viaduct, or be tunnel, another side is viaduct.
Assuming that back-shaped channel setting is on lateral road, if straight way craspedodrome flow is comparatively large, for expanding straight way straight-going traffic amount, craspedodrome tunnel or viaduct can be set at straight way, sees Fig. 3 ~ Fig. 6.
If landform or the restriction of other factors, can not overcome very well motor vehicle shunting and and flow time cause problem on obstacle, double back shape traffic system can be set, see Fig. 7, namely back-shaped passage is all set on two roads, bending channel can near intersection, but to directly not enter front bending channel by regulation craspedodrome motor vehicle, and enter other direction bending channel and turn direction after turning right in intersection, turn right in intersection and enter front bending channel, namely specify that the motor vehicles of only turning right can enter bending channel, bending channel motor vehicle out can only be turned right simultaneously.
Bend is imported and exported and is generally arranged on both sides of the road, if space allows also to select a track to arrange, bend imports and exports or utilize intermediate isolating band to arrange import and outlet.
